A JWST Near- and Mid-Infrared Nebular Spectrum of the Type Ia Supernova 2021aefx

Lindsey A. Kwok, Saurabh W. Jha, Tea Temim +55

We present JWST near- and mid-infrared spectroscopic observations of the nearby normal Type Ia supernova SN 2021aefx in the nebular phase at days past maximum light. Our Nea…

JWST Imaging of the Cartwheel Galaxy Reveals Dust Associated with SN 2021afdx

Griffin Hosseinzadeh, David J. Sand, Jacob E. Jencson +12

We present near- and mid-infrared (0.9-18 m) photometry of supernova (SN) 2021afdx, which was imaged serendipitously with the James Webb Space Telescope (JWST) as part of its Ea…

Explosion mechanism of core-collapse supernovae: role of the Si/O interface

Luca Boccioli, Lorenzo Roberti, Marco Limongi +2

We present a simple criterion to predict the explodability of massive stars based on the density and entropy profiles before collapse. If a pronounced density jump is present near…

Cosmic nucleosynthesis: a multi-messenger challenge

Roland Diehl, Andreas Korn, Bruno Leibundgut +2

The origins of the elements and isotopes of cosmic material is a critical aspect of understanding the evolution of the universe. Nucleosynthesis typically requires physical conditi…

SN2017jgh - A high-cadence complete shock cooling lightcurve of a SN IIb with the Kepler telescope

P. Armstrong, B. E. Tucker, A. Rest +69

SN 2017jgh is a type IIb supernova discovered by Pan-STARRS during the C16/C17 campaigns of the Kepler/K2 mission. Here we present the Kepler/K2 and ground based observations of SN…

Metallicity-dependent nucleosynthetic yields of Type Ia supernovae originating from double detonations of sub-M white dwarfs

Sabrina Gronow, Benoit Cote, Florian Lach +4

Double detonations in sub-Chandrasekhar mass carbon-oxygen white dwarfs with helium shell are a potential explosion mechanism for a Type Ia supernova (SNe Ia). It comprises a shell…

Photometry of Some Recent Gamma-ray Bursts

József Kóbori, János Kelemen, Péter Veres +2

We present the results of the optical, X-ray and gamma-ray analysis of some recent GRBs. The data were obtained by the automated P60 telescope and the Swift telescope (UVOT, XRT an…
