Abstract We are now underway in our intensive study of supernovae with HST. This long-term project promises to illuminate problems in stellar evolution, the mechanism of stellar explosion, nucleosynthesis, the energetics of interstellar gas, and the extragalactic distance scale. Initial observations, starting in the Spring of 1992, show that HST observations of SN 1987A are rich in content and that these high- minded goals can actually be achieved. Our HST observations of a new supernova, SN1992A, demonstrate that Target-of-Opportunity observations with HST are worth the effort. We were poised to observe SN 1993J in M81 and we obtained a beautiful UV/optical spectrum from an early epoch of this peculiar supernova. Our long-term plan is to continue the imaging and spectroscopy of SN 1987A, to obtain unprecedented late-time UV spectra of SN 1993J, and to realize the promise of our Cycle 1 proposal by following the late-time light curves of SN 1992A and SN 1993J. SN 1992A and SN 1993J demonstrated our ability to orchestrate observations from the ground, with IUE, and from HST to investigate important issues in supernova research. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. We will observe three different supernovae in this Cycle 4 program: SN 1987A, SN 1992A, and SN 1993J. Our intention here is to give a narrative description of the observations described in the exposure log sheets. SN 1987A SN 1987A has been the object of our Cycle 1, 2, and 3 observing programs. Our goal is to continue this work, taking advantage of the improvements in telescope performance promised by COSTAR and WFPC2. We have used the FOS to obtain spectra from 1650-9200 angstroms using gratings G190H,G270H,G400H, G570H, and G780H with the red side detector. Since the supernova is close to two bright neighbor stars, we have used a careful offset acquisition, starting with a binary acquisition of the FOS offset star, then offsetting to the supernova debris and peaking up on the target, which should be about 19 mag in 1994. The supernova is surrounded by a ring of circumstellar material, whose spectrum we also wish to measure. We would like to move from the supernova debris to the ring (which is less than 1" away) and accumulate a spectrum at that location. It is important to keep these observations grouped so that the ring spectrum is obtained using the telescope position established by the debris spectrum This set of observations is to be made at two different times in Cycle 4: near the beginning, and approximately 200 +/- 50 days later. The other set of observations for SN 1987A is a set of photometric measures. These data will be used to continue the light curve of SN 1987A, and they should also have adequate signal to be useful for measurements of the source size and shape using PC1 in WFPC2. The filters are F160BW (the blocked Woods filter), F255W, F336W, F439W, F555W, F658N (for the ring), F675W, F814W, and F502N (also for emission from the ring). A second epoch of observations (the SN87PHOTB sequence) is requested that includes the broad band filters, but not the two narrow filters used to measure the structure of the circumstellar ring. As for the spectra, we would like the first set of observations early in Cycle 4 and the second epoch about 200 days later. The second supernova we would like to observe is SN 1993J, for which we have FOS data from 1993. Our acquisition method is to acquire an offset star using a binary search, offset to the supernova and peak up, then to accumulate the red side spectrum in a sequence of FOS gratings. The gratings are G190H, G270H, and G400H. We would also like to carry out photometry of SN 1993J, again using the PC1 chip on WPFC2. The filters are F336W, F439W, F555W, F675W, and F814W. This would be of the greatest utility if placed late in Cycle 4, as the ground-based data become more difficult to obtain. A similar set of observations, omitting only the U filter, is planned for SN 1992A, which has an extensive ground-based light curve. We will make B, V, R, I measurements with WFPC2. Observations near the beginning of Cycle 4 would be best, as we already anticipate an apparent magnitude near 24. Page 4 ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. We have been very active in carrying forward this general program of research using IUE and ground-based facilities, and we know exactly what you can and cannot do with each. You cannot carry out the program of UV spectsoscopy outlined here with IUE, despite its much simpler scheduling constraints. The HST spectra go farther into the UV, they have much better spectral resolution, and the slit is much smaller so that contamination is not so serious a problem. You cannot follow a 13 mag supernova for 45 days (as we did for SN 1992A) with IUE because the flux declines by a factor of 100, and it is utterly pointless to make an observation at age 300days, which we have succesfully done with HST. We have established a long-term program at KPNO on the 2.1 meter to help us get complementary photometry for the supernovae we study with HST. We have time assigned at the MMT and Mount Hopkins to obtain complementary spectroscopy and photometry from the ground and we have added observers at CTIO and at Lick to the SINS team. The HST photometry will only be carried out for magnitude 21 and below, since we can easily monitor the supernova flux from the ground down to this point. But the most interesting era is the very latest one, when the departures form a pure exponential may signal new physics in the energy supply. From mag 22 to 25, the HST data will be unique and provide the best information on the transition from a supernova to a supernova remnant. For SN 1987A, the HST data are absolutely essential, even for accurate BVRI photometry, to say nothing of resolving the debris. Our UV spectra are unique and even the spectrum in the optical region is better than any published ground based data from this epoch. All of this will continue to be true-- only more so as the supernova fades and its very close companions do not. Every previous time we have answered this question we were guessing. Now we have one set of data for each aspect of our program and we can begin to make realistic estimates based on real experience. For example, the [O III] image shown in Figure 1 is the result of summing 4700 seconds of exposure. It has about 25 counts/pixel and is none too deep for beginning image restoration or for trying to measure the rate of decline in separate knots. By the beginning of cycle 3, a comparable image will take 9000 seconds. But the chance will never come again, and it will take less time with the improved optics in Cycle 4. Investing in these data now will make the future observations more valuable. We recognize that these measurements take a lot of telescope time, and we have pared our set of filters to the essential minimum for achieving our scientific goals. The most difficult issue is not calculating a reasonable exposure time( as you can judge from some of the figures shown), but selecting the optimum interval between data sets. The supernova is fading slowly, but it changes significantly on the time scale of six months, which is comparable to the light travel time across the debris. Extremely interesting events, such as the collision of the debris with the circumstellar shell, are likely to take place on this timescale. It seems prudent to observe SN 1987A with about that frequency, and that is what we have requested. Page 5 ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Since our observations are of slowly (or not so slowly) fading supernovae, the timing of the observations is extremely important. SN 1987A: We want to continue the observations begun in Cycles 1, 2, and 3. For the spectra, this means making observations at two epochs, one near the start of Cycle 4, and another about 200 days later. This spacing will give a good record of the spectral changes in both the supernova debris and in the circumstellar matter. The images will be used to extend the photometric record for SN 1987A. An observation near the start of Cycle 4 (and near the time of the first spectrum) would be ideal. The second observation should follow by the approximately the same 200 day interval. SN 1993J: This object is still fairly bright (14), but will be fading from now until our first observation in Cycle 4. The best timing would be for this observation to be in the second half of Cycle 4-- roughly December 1994. Earlier observations are acceptable, but observations near this date will provide the best transition from ground-based observations to HST data. SN 1992A: Here, the object is already old and faint. Observations in the first half of Cycle 4 are preferable, but we could use data at any time in the Cycle. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. We have very good access to ground based facilities which are essential to getting the most out of our HST data. We have the ability to get spectra from the 1.5m at Mount Hopkins, and photometry from the 1.2m telescope there. We have regular assignments on the MMT and at the KPNO 2.1m that ensure we can get the observations of the supernovae when they are faint at age 1 year. We haveen listed the CTIO and Berkeley observers to the SINS team. They have been outstandingly effective observers of supernovae.

Although we are still receiving our Cycle 1 data, we are beginning to obtain some results. SN 1987A: The earliest observations resulted in the detection of circumstellar ring-- as described in Jakobsen et al below Subsequent use of the ring geometry and fluorescent line time delay enabled a measurement of the distance to the LMC--see Panagia et al below. Work in progress includes identification of new lines in the circumstellar spectrum and measurement of lines in the supernova debris. These will becompared tomodel calculations. This was reported at the Sardinia HST meeting byKirshner. Measurement of changes in the circumstellar shell and image restoration were reported at AAS by Phil Plait. The measurement of the debris diameter is nearly completed. For SN 1992A, we have combined the data from HST, IUE, and CTIO to write a giant paper that compares this supernova with the results of stellar evolution calculations and supernova explosion models. We conclude that SN 1992A cannot be the result of the explosion most frequently used to model supernova spectra,and it is also not the result of the ``late detonation'' model developed tomatch someother well observed SN Ia. Good data are in hand for SN 1993J, but it is too soon to cite results. P. Jakobsen, R. Albrecht, C. Barbieri, J.C. Blades, A. Boksenberg, P. Crane, J.M. Deharveng, M.J. Disney, T.M. Kamperman, I.R.

Resources to be supplied by investigator's institution(s). Our institutions provide the basic salary support for all the senior investigators on this project. Students typically receive tuition waivers orfellowship support from the institution in addition to their research stipend. Allof our intitutions have made significant cost-sharing contributions to supplycomputers for this work and they routinely operate extensive networks at no cost to us. At CfA, we have access to considerable software help and hardware for preparationof slides and photographs. Our institutions support the ground- basedobservatories we use to augment this HST work, most significantly CTIO, Lick, andthe MMT. We have many external benefits, such as a preprint series, anextensive astronomical library, and some visitors which are provided without cost tothis project. CfA postdoc Brian Schmidt is not supported by HST funds, butcontributes to the project. Similarly, Bruno Leibundgut is supported by the SwissNational Science Foundation, and not by the HST. Harvard handles the subcontractsto eachof the other institutions without any additional overhead charge. Butbest of all, our institutions provide a rich intellectual atmosphere includingexperts on atomic data, radiative transfer, nucleosynthesis, hydrodynamics ,numerical methods, stellar evolution, shock waves, and supernova observations at otherwavelengths. More than any details of return from the overhead pool, webenefit from the depth of our surroundings. ------------------------------------------------------------------------------------ 11.
