It wasn't until 2014, however, that the community obtained the first direct post-explosion detection of a surviving companion to a SESN (Type IIb SN 1993J). Since then, there have been four more, including the first fully stripped Type Ib/c SN 2013ge this past year. The field is now past the point of targeting individual systems one at a time. A statistically complete companion-mass distribution (including deep upper limits) can provide important constraints on the underlying physics used in binary evolution models (e.g., winds, rotation, metallicity, nuclear burning instabilities), which in turn has far-reaching implications in all of astrophysics, including merger sources for gravitational waves. Building the proper dataset is a slow process given the small number of viable candidates each year (considering distance, extinction, etc.). Here we propose optical+UV observations at the sites of the two most viable SESNe targets of this year to detect (or place meaningful limits on) any surviving companion. NUV (F275W/F336W) imaging offers an optimum detection strategy for the expected hot, blue stellar companions, while optical imaging can rule out shock interaction contributions and probe less likely, but possible, cooler star companions. We also propose ongoing monitoring of SN 2013ge. Given HST's time horizon, the degrading UV response on WFC3, and the requisite waiting period to allow the SN to fade before conducting a companion search, now is the time to take full advantage of HST's unique UV capabilities. ------------------------------------------------------------------------------------ 17203( 5) - 02-May-2023 19:19:13 - [ 2] Observations Description ------------------------ WFC3: - Use entire array to aquire fiducial stars for alignment purposes - Use 512_UVIS2_CTE aperture to minimize photon transfer losses - When scheduled, please have CS contact PI to finalize pos_tag based on final orientation - EXPTIME (actual): -SN 2016coi (9 orbit) -F275W (13803 s) -F336W (8082 s) -F438W (1000 s) -F555W (700 s) -SN 2017gax (9 orbit) -F275W (13803 s) -F336W (8082 s) -F438W (1000 s) -F555W (700 s) -SN 2013ge (4 orbits) -F336W (8082 s) -F555W (700 s) - FLASH = varies with aim of minimizing photon transfer losses and read noise - Note prior email to Sylvia. Hope all is well. Tis the night before Phase 2's are due, and I need a clue. We are wondering about Flash settings. - Here is the situation: *We are trying to detect a single, very faint source (surviving star from a supernova). We only care about one position, not the entire field. *We have placed the pointing in the center of the UVIS2-512C-CTE aperture, so that will help with the CTE. *We are not sure what the background from the galaxy looks like, but it may contribute to the flux slightly (or not at all). *It is easy to adjust the Flash value in APT to turn the warning off, but we are hoping we aren't adding too much noise unnecessarily, as this source is faint. - 4 pt WFC3-UVIS-DITHER-Box -We use 4 POS TARGS instead *Impact of Gyros* We have considered the impact of reduced gyro operations on our program. The only problematic observation is SN 2013ge, which has 9 orbits requested. We were able to successfully reduce this target to 4 visits, each with 2-3 orits per visit. The only condition is that all filters must be obtained in the same orientation for several reasons, including time variablility and optimized sampling and reductions. Therefore, we have added this constraint. ------------------------------------------------------------------------------------ 17203( 5) - 02-May-2023 19:19:13 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SN-2016COI EXT-STAR, SUPERNOVA RA=21H59M4.1400S, J2000 V = 25.0 TYPE IB DEC=+18D11'10.50" Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 2 SN-2017GAX EXT-STAR, SUPERNOVA RA=04H45M49.4300S, J2000 V = 25.0 TYPE IB DEC=-59D14'42.56" Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 4 SN-2013GE EXT-STAR, SUPERNOVA RA=10H34M48.4610S, J2000 V = 25.0 TYPE IB DEC=+21D39'41.90" Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
