Spectral Modeling of Type II Supernovae [PDF]

AIP Conference Proceedings, 2007
Using models of the SN~IIP 2005cs, we show that detailed spectral analysis can be used to determine reddening and abundances.

Core-collapse supernovae ages and metallicities from emission-line diagnostics of nearby stellar populations

, 2018
Massive stars are the main objects that illuminate H II regions and they evolve quickly to end their lives in core-collapse supernovae (CCSNe). Thus it is important to investigate the association between CCSNe and H II regions.

Neutrinos from Type-II Supernovae

Abstract In our work we investigate the stellar surface fluxes of different neutrino flavors, both with and without matter effects, while aiming to consider the varying density of the progenitor star to reveal intriguing variations in their behavior. By examining both normal and inverted neutrino mass hierarchies in studies of neutrino fluxes,

JWST Observations of SN 2023ixf. I. Completing the Early Multiwavelength Picture with Plateau-phase Spectroscopy

The Astrophysical Journal
We present and analyze panchromatic (0.35–14 μ m) spectroscopy of the Type II supernova 2023ixf, including near- and mid-infrared spectra obtained 33.6 days after explosion during the plateau phase, with the James Webb Space Telescope (JWST). This is the

NEOWISE-R Caught the Luminous SN 2023ixf in Messier 101

The Astrophysical Journal
During routine survey imaging, the reactivated Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE-R) serendipitously caught the Type II supernova SN 2023ixf in Messier 101 on the rise, starting day 3.6 through day 10.9, and again on the ...
