I did not include any time constraints, let me know if that should be changed. There are also several "errors" about orbit numbering/order withthe new HOPR visits, but I think that is due to the completed visits? Either way, I can't get it to go away. The "orbit overrun" errors do not seem to correspond to the new HOPR visits. -1980910592 ----- Attempting Submission 1 (Mon Sep 04 14:46:03 GMT 2023) ----- HST Phase II Proposal 17429 successfully submitted.

Elevating the Scientific Output of JWST by using HST to Examine the Heart of Type Ia Supernova 2021aefx Despite Type Ia supernovae (SNe Ia) remaining a benchmark of precision cosmology, a consensus on how and why some white dwarfs explode as SNe Ia eludes the astronomical community. Photometric observations of SNe Ia at late times measure the conversion efficiency of radioactive decay energy into photons. We request 10 orbits of HST/WFC3 observations in Cycle 31 and 8 orbits in Cycle 32 to observe the normal SN Ia 2021aefx at 750d, 1000d, and 1150d after the explosion in conjunction with already awarded JWST near- and mid-infrared spectra. These complimentary HST and JWST observations provide complete wavelength coverage from 0.4-14 microns spanning years after the explosion. Such data are non-existent in the literature and we do not foresee similar opportunities in the overlapping lifetimes of HST and JWST. Measuring the complete spectral energy distribution at nebular phases allows a direct estimate of the total radioactive decay energy, which in turn depends on the nucleosynthetic yield of the explosion. Many correlations have been proposed for estimating the nucleosynthetic yield of a SN Ia but uncertainties regarding emission in the mid-IR prevented definitive conclusions. With the proposed HST/WFC3 time we can elevate the scientific output from this SN to a level that JWST cannot reach alone, and SN~2021aefx will become a once-in-a-decade event that paves the way for the next generation of SN Ia models. Late-time observations of SN Ia 2021aefx at 750d and 1000d coinciding with JWST observations using F438W, F555W, F600LP, F110W, and F160W filters.
