Abstract We propose to obtain STIS and FGS1R observations of the long- period (20.3 yrs) eclipsing binary VV Cephei (M2 Iab + B0) as it continues to emerge from chromospheric eclipse. We will also obtain comparison spectra of the similar, but less interacting (and non-eclipsing) binaries KQ Pup and HR 8164. This project is a continuation of the Cycle 7 medium length program ``The 1997/98 Eclipse of VV Cephei'' (GO-7269), which used the STIS high resolution echelle modes to probe the chromosphere of the M supergiant primary. This is done by observing the absorption spectrum of the primary's chromosphere, which appears superimposed upon the companion's early-type continuum. Repeated monitoring of the evolution of the chromospheric absorption spectrum during egress from total eclipse permits the construction of an empirical model of the chromosphere and wind of the M2 supergiant. VV Cep is unique among eclipsing binaries in being sufficiently bright for high resolution spectroscopy. Th e proposed STIS observations will probe the wind acceleration region; obtaining empirical information here is of crucial importance in understanding the nature of energy and momentum deposition in these cool winds. In addition, we will observe VV Cep with the newly implemented FGS1R in TRANSFER mode in order to obtain relative orbit information, and accurate stellar masses. ------------------------------------------------------------------------------------ 8257( 10) - 12/28/99 13:10 - [ 2] Observations Description ------------------------ The proposed STIS and FGS1R observations will begin when the present GO program 7269 ends (in June 1999). We propose to make two visits in Cycle 8, and one visit in each of Cycles 9 & 10, to supplement the extensive data set that will be obtained by GO-7269. These observations will use the STIS medium and high resolution echelle modes. In particular, we will use several tilts of E230H spanning 2120--3150 Angstrom, two E140H tilts spanning 1240--1630 Angstrom, and the E140M and short wavelength primary setting of E230M to complete the spectral coverage. We will also obtain G230LB and G430L low resolution spectra through a photometric aperture at each visit. These absolute fluxes in combination with the observed eclipse durations, will be used to determine stellar radii (see Bennett et al.\ 1996 for detailed method). All of these observations will be scheduled as CVZ visits, greatly enhancing the efficiency of the proposed observing program. We plan to obtain a S/N ~ 30 in the c ontinuum. To estimate the exposure times out of eclipse we used a combination of IUE spectra LWP21568 and SWP42943 of VV Cep input to the STIS exposure simulator. Maximum count rates, both the local and global, are well below the MAMA bright limits in the brightest IUE spectrum. Typical continuum flux levels are 4.0d-12 ergs cm^-2 s^-1 AA^-1. The largest flux occurs in the Mg II emission lines near periastron (far from eclipse) at about 1.0d-11 ergs cm^-2 s^-1 AA^-1. The fluxes of the comparison stars, KQ Pup and HR 8164, although brighter, are still below the MAMA bright limits. The proposed STIS observations will sample the absorbing column density along the B star line of sight as its sweeps through the chromosphere and wind of the M supergiant primary. The diagnostics of interest include the resonance and low-lying lines of C I--II, N I, O I, Mg I--II, Al I--III, Si I--III, and a large number of lines of Fe I-II, and UV multiplet 34 of Fe III. In particular, lines of Fe I RMT multiplets 9, 11, 30, and UV 1, 2, 5--9, 11, 14, 44, 46, 52, 87, 156 and of Fe II multiplets Fe II UV 1, 2 3, 32, 33, 35, 36, 60--64, 78, 117, 144--147, 158--161, 164, 171--178, 195--205, etc. have measured oscillator strengths (Fuhr, Martin, & Wiese 1988) and will be observed at high resolution (R ~ 110, 000). There are also a large number of lines of Ni II, Cr II, and several Si I, Mn II and Ti II lines with measured oscillator strengths that will be observed at high resolution. All of the Fe I--II and Ni II lines come from low-lying even parity levels from which further radiative decays are strongly forbidden. We will use the superb spectral resolution and S/N of the STIS echelle modes to separate the narrow chromospheric and wind lines from the broad, variable, ``shell'' absorption features. We also propose to obtain FGS1R observations during each of the 4 VV Cep visits, and the visits to the two comparison stars (KQ Pup & HR 8164). These observations will be perfo rm ed in TRANSFER mode, which will allow spatial resolution of the ``visual orbit'' of VV Cep, using a F5ND neutral density filter because of the brightness of the sources. In combination with the known spectroscopic orbit, stellar masses can be determined. The use of additional constraints provided by the UV fluxes, and eclipse durations allows the stellar radii to be determined. The proposed solution procedure is identical to that followed by the PI for Zeta Aur (Bennett et al.\ 1996). Since the additional time required to time required obtain the FGS scans (acquire new guide stars, obtain scans, and overhead) is only about 25 mins., these observations can easily be fitted into the end of one of the CVZ visits. Therefore, the FGS observations yield a substantial science return at very little cost to the observing program. The main drawback is the need to obtain special FGS1R calibration observations, of standard single stars matching the spectral types of the VV Cep component s (M2 Iab and B0), at a time near the science observations because of slow changes in the shape of the FGS reference S-curves over time. In any case, there is no suitable M supergiant reference S-curve in the FGS transfer mode color library. The calibrators we propose are Mu Cep (M2 Ia) and Lambda Lep = HD 34816 (B0.5 IV). The latter is an FGS3 reference library target, but no M supergiant is listed in the calibration library. We request an additional 2 orbits per Cycle to acquire the necessary FGS1R calibration S- curves. For Cycle 8 we will request only one set of calibration visits to be done roughly midway between the planned science observations. Since the planned FGS calibration exposures will only take a fraction of the available orbit visibility, we will make use of the remaining time by obtained STIS reference spectra of the calibrators. These spectra will be useful for spectral decomposition of the combined light photospheric spectrum (especially in the ``optical UV' ' from 3000--4000 Angstrom). This will be of particular use in determining stellar radii from the eclipse durations and absolute UV and optical fluxes. Note that Mu Cep lies in the CVZ; this FGS calibration observation will be scheduled as a CVZ visit to maximize the available visibility. Real Time Justification ----------------------- All of the observations of VV Cep will be scheduled as CVZ visits. VV Cep lies in the heart of the CVZ, and has CVZ windows available every HST precession period of 56 days. The single visit to HR 8164 will also be scheduled as a CVZ visit, as will the visit required to obtain the calibration FGS1R S-Curve of Mu Cep. VV Cep is a FUSE Cycle 1 GTO target (PI: Wilkinson), and we will attempt to coordinate the proposed HST/STIS & FGS observations with the FUSE schedule, when that becomes available (the PI is a Co-I on the FUSE GTO proposal). In addition, Ed Guinan will be obtaining coordinated UBVRI photometry of VV Cep with the Villanova 38 cm telescope, and the Mt.\ Hopkins 0.8 m APT\@. Stephenson Yang will obtain coordinated optical spectra in the HAlpha region, and of the Balmer lines H8--H10 near 3800 Angstrom, at the Dominion Astrophysical Observatory (DAO) 1.2 m telescope as part of the PI's ongoing radial velocity and HAlpha monitoring program. The PI is also obtaining c oo rdinated continuum radio fluxes of VV Cep using the VLA (program AB865 and AB875).
