JWST Spectroscopy of Type Ia Supernova 2025rbs from Maximum Light to the Nebular Phase
Lindsey A. Kwok, Stéphane Blondin, Adam A. Miller +53
We present JWST observations of the Type Ia supernova (SN Ia) 2025rbs (14.5 Mpc) at +1, +23, and +84 days after B-band maximum, spanning peak light through a wavelength-depende…
JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Colin W. Macrie, Conor Larison, Huei Sears +43
We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from 2 weeks before to 1 year after maximum light. JWST near- and mid-infrared sp…
JWST Spectroscopy of SN Ia 2022aaiq and 2024gy: Evidence for Enhanced Central Stable Ni Abundance and a Deflagration-to-Detonation Transition
Lindsey A. Kwok, Chang Liu, Saurabh W. Jha +48
We present optical + near-infrared (NIR) + mid-infrared (MIR) observations of the normal Type Ia supernovae (SN Ia) 2022aaiq and 2024gy in the nebular phase, continuously spanning…
The Heavy Element Enrichment History of the Universe from Neutron Star Mergers with Habitable Worlds Observatory
Eric Burns, Jennifer Andrews, Robert Szabo +23
Understanding where elements were formed has been a key goal in astrophysics for nearly a century, with answers involving cosmology, stellar burning, and cosmic explosions. Since 1…
Type Ia supernovae
Stéphane Blondin
Type Ia supernovae (SNe Ia) correspond to the thermonuclear explosion of a carbon-oxygen white dwarf (C-O WD) star in a binary system, triggered by the accretion of material from a…
Type Ia supernova explosion models are inherently multidimensional
R. Pakmor, I. R. Seitenzahl, A. J. Ruiter +5
Theoretical and observational approaches to settling the important questions surrounding the progenitor systems and the explosion mechanism of normal Type Ia supernovae have thus f…
