SN 2021pfs: A Type Ia Supernova Likely Affected by Progenitor Metallicity, as Revealed by Comparison with Its Twin Counterpart
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +15
We present extensive photometric and spectroscopic observations of the normal type Ia supernovae (SNe Ia) 2021pfs, which occurred in the Seyfert 2 galaxy NGC 5427 at a redshift 0.0…
Evidence for the First Globular Cluster Stellar Stream beyond the Milky Way
Julie Kiel Holm, Sarah Pearson, Jacob Nibauer +5
The dark matter content of ultra-diffuse galaxies is the subject of considerable debate. Stellar streams, which form when a host galaxy tidally strips stars from an orbiting stella…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
The Carbon Giant Population Revealed by Gaia DR3
Benjamin R. Roulston, Paul J. Green
Classical carbon stars (atmospheric C/O >1) are asymptotic giant branch (AGB) stars that become carbon-rich through third dredge-up during the thermally pulsing AGB phase. However,…
Radiative Transfer Modeling of Stripped-envelope Supernovae II: Neural Network Emulation of Light Curves
S. Karthik Yadavalli, V. Ashley Villar, Maria R. Drout +3
We present the first neural-network emulator of stripped-envelope supernova (SESN) lightcurves, trained on a grid of 4499 light curves simulated with the radiative transfer (RT) co…
Three-Dimensional Expansion of Iron Ejecta in Cassiopeia A with Chandra and XRISM
Aya Bamba, Tomoki Kadoya, Kouichi Hagino +4
Measurement of the expansion structure of ejecta in supernova remnants (SNRs) provides important information about their explosion mechanism. We combine Chandra proper-motion measu…
