Panchromatic JWST Observations and Models of the Dim Type Iax Supernova 2024vjm at 200 days
E Baron, J. M. DerKacy, C. Ashall +23
We report JWST spectra and photometry of the underluminous SN Iax 2024vjm obtained 202.8 restframe days post-explosion. The spectrum exhibits a rich set of forbidden lines from low…
Three-dimensional Structure of Incomplete Carbon-Oxygen Detonations in Type Ia Supernovae
A. Khokhlov, I. Dominguez, A. Y. Chtchelkanova +6
Carbon-oxygen (CO) detonation with reactions terminating either after burning of C in the leading C + C reaction or after burning of C and O to S…
Type Ia Supernova Progenitor Properties and Their Host Galaxies
Sudeshna Chakraborty, Benjamin Sadler, Peter Hoeflich +16
We present an eigenfunction method to analyze 161 visual light curves (LCs) of Type Ia supernovae (SNe Ia) obtained by the Carnegie Supernova Project to characterize their diversit…
A JWST Medium Resolution MIRI Spectrum and Models of the Type Ia supernova 2021aefx at +415 d
C. Ashall, P. Hoeflich, E. Baron +39
We present a JWST MIRI/MRS spectrum (5-27 m) of the Type Ia supernova (SN Ia), SN 2021aefx at days past -band maximum. The spectrum, which was obtained during…
