Will a Supernova explode in CD-30°11223?
L. Piersanti, L. R. Yungelson, E. Bravo +1
Accretion of He-rich matter onto a low-mass CO WD from a He-rich donor may lead to an explosive event of SN Ia proportion, though with low peak luminosity and peculiar nucleosynthe…
JWST Low-Resolution MIRI Spectral Observations of SN~2021aefx: High-density Burning in a Type Ia Supernova
J. M. DerKacy, C. Ashall, P. Hoeflich +38
We present a JWST/MIRI low-resolution mid-infrared (MIR) spectroscopic observation of the normal Type Ia supernova (SN Ia) SN 2021aefx at +323 days past rest-frame B-band maximum l…
Pre-explosive accretion and simmering phases of Type Ia Supernovae
Luciano Piersanti, Eduardo Bravo, Oscar Straniero +2
In accreting WDs approaching the Chandrasekhar limit, hydrostatic carbon burning precedes the dynamical breakout. During this \textit{simmering} phase, captures are energetical…
A First Transients Survey with JWST: the FLARE project
Lifan Wang, D. Baade, E. Baron +43
JWST was conceived and built to answer one of the most fundamental questions that humans can address empirically: "How did the Universe make its first stars?". Our First Lights At…
Type Ia Supernovae keep memory of their progenitor metallicity
Luciano Piersanti, Eduardo Bravo, Sergio Cristallo +4
The ultimate understanding of Type Ia Supernovae diversity is one of the most urgent issues to exploit thermonuclear explosions of accreted White Dwarfs (WDs) as cosmological yards…
Supernova 2014J at M82: II. Direct Analysis of Spectra Obtained with Isaac Newton and William Herschel Telescopes
Patrick Vallely, M. E. Moreno-Raya, E. Baron +19
We analyze a time series of optical spectra of SN~2014J from almost two weeks prior to maximum to nearly four months after maximum. We perform our analysis using the SYNOW code, wh…
