The Progenitors of Recent Core-Collapse Supernovae [PDF]

open access: yes, 2009
We present the results of our analysis of Hubble Space Telescope (HST) and deep ground-based images to isolate the massive progenitor stars of the two recent core-collapse supernovae 2008 bk and 2008 cn.

Optical observations of core-collapse supernovae

open access: yesAIP Conference Proceedings, 2001
I present an overview of optical observations (mostly spectra) of Type II, Ib, and Ic supernovae (SNe). SNe II are defined by the presence of hydrogen, and exhibit a very wide variety of properties. SNe II-L tend to show evidence of late-time interaction with circumstellar material.

Understanding Core-Collapse Supernovae

open access: yesNuclear Physics A, 2010
Our understanding of core-collapse supernovae continues to improve as better microphysics is included in increasingly realistic neutrino-radiationhydrodynamic simulations. Recent multi-dimensional models with spectral neutrino transport, which slowly develop successful explosions for a range of progenitors between 12 and 25 solar mass, have motivated ...

Optimizing the potential of KM3NeT in detecting core-collapse supernovae

open access: yes
Core-collapse supernovae mark the end of life of massive stars. However, despite their importance in astrophysics, their underlying mechanisms remain unclear.

Probing the Shock Breakout Signal of SN 2024ggi from the Transformation of Early Flash Spectroscopy

open access: yesThe Astrophysical Journal Letters
We present early-time, hour-to-day cadence spectroscopy of the nearby Type II supernova (SN II) 2024ggi, which was discovered at a phase when the SN shock had just emerged from the red supergiant (RSG) progenitor star.

Discovery and Extensive Follow-up of SN 2024ggi, a Nearby Type IIP Supernova in NGC 3621

open access: yesThe Astrophysical Journal
We present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 ± 0.3 Mpc. The SN was caught $5.{8}_{-2.9}^{+1.9}$ hr after its explosion by the ATLAS survey.

Rise-times of Core-Collapse Supernovae [PDF]

open access: yes
A supernova is the explosive end of a star. If the star is a white dwarf in a binary system, the supernova will be a thermonuclear or type Ia supernova.

Searching for Progenitors of Core-Collapse Supernovae [PDF]

open access: yes, 2005
Identifying the massive progenitor stars that give rise to core-collapse supernovae is one of the main pursuits of supernova and stellar evolution studies.
