Theory holds that a star born with an initial mass between about 8 and 140 times the mass of the Sun will end its life through the catastrophic gravitational collapse of its iron core to a neutron star or black hole. This core collapse process is thought to usually be accompanied by the ejection of the star’s envelope as a supernova. This established theory is now being tested observationally, with over three dozen core-collapse supernovae having had the properties of their progenitor stars… Expand

Hydrogen-rich Core Collapse Supernovae
Hydrogen-rich core collapse supernovae, known as "Type II" supernovae, are the most common type of stellar explosion realized in nature. They are defined by the presence of prominent hydrogen linesExpand

A MASSIVE PROGENITOR OF THE LUMINOUS TYPE IIn SUPERNOVA 2010jl
The bright, nearby, recently discovered supernova (SN) 2010jl is a luminous Type IIn SN. Here, we report archival Hubble Space Telescope (HST) observations of its host galaxy UGC 5189A taken roughlyExpand

Abstract Supernovae of all types exhibit time-dependent spectropolarimetric signatures produced primarily by electron scattering. These reveal the presence of aspherical and variable phenomena suchExpand
The ring nebula around the blue supergiant SBW1: pre-explosion snapshot of an SN 1987A twin
SBW1 is a B-type supergiant surrounded by a ring nebula that is a nearby twin of SN 1987A’s progenitor and its circumstellar ring. We present images and spectra of SBW1 obtained with the Hubble SpaceExpand
CALTECH CORE-COLLAPSE PROJECT (CCCP) OBSERVATIONS OF TYPE II SUPERNOVAE: EVIDENCE FOR THREE DISTINCT PHOTOMETRIC SUBTYPES
We present R-band light curves of Type II supernovae (SNe) from the Caltech Core-Collapse Project (CCCP). With the exception of interacting (Type IIn) SNe and rare events with long rise times, weExpand
Graphite grains in supernova ejecta – Insights from a noble gas study of 91 individual KFC1 presolar graphite grains from the Murchison meteorite
We have measured helium and neon concentrations, elemental and isotopic ratios of 91 individual presolar graphite grains from the KFC1 density separate of the Murchison meteorite. Eleven grainsExpand

Progenitors of Core-Collapse Supernovae
Knowledge of the progenitors of core-collapse supernovae is a fundamental component in understanding the explosions. The recent progress in finding such stars is reviewed. The minimum initial massExpand
Supernova 2007bi as a pair-instability explosion
TLDR
Observations of supernova SN 2007bi are reported, a luminous, slowly evolving object located within a dwarf galaxy, and it is shown that >3 of radioactive 56Ni was synthesized during the explosion and that the observations are well fitted by models of pair-instability supernovae. Expand
The evolution and explosion of massive stars
Like all true stars, massive stars are gravitationally confined thermonuclear reactors whose composition evolves as energy is lost to radiation and neutrinos. Unlike lower-mass stars (M≲8M⊙),Expand
A giant outburst two years before the core-collapse of a massive star
TLDR
It is reported that the peculiar type Ib supernova SN 2006jc is spatially coincident with a bright optical transient that occurred in 2004, andSpectroscopic and photometric monitoring of the supernova leads us to suggest that the progenitor was a carbon-oxygen Wolf–Rayet star embedded within a helium-rich circumstellar medium.

The massive binary companion star to the progenitor of supernova 1993J
TLDR
Photometric and spectroscopic observations of SN1993J ten years after the explosion detect the unambiguous signature of a massive star: the binary companion to the progenitor. Expand
How Massive Single Stars End Their Life
How massive stars die—what sort of explosion and remnant each produces—depends chiefly on the masses of their helium cores and hydrogen envelopes at death. For single stars, stellar winds are theExpand
A Core-collapse Supernova Model for the Extremely Luminous Type Ic Supernova 2007bi: An Alternative to the Pair-instability Supernova Model
We present a core-collapse supernova (SN) model for the extremely luminous Type Ic SN 2007bi. By performing numerical calculations of hydrodynamics, nucleosynthesis, and radiation transport, we findExpand
Ruling out a massive asymptotic giant-branch star as the progenitor of supernova 2005cs
We calculate the predicted UBVRIJHK absolute magnitudes for models of supernova progenitors and apply the result to the case of supernova 2005cs. We agree with previous results that the initial massExpand
On the role of continuum-driven eruptions in the evolution of very massive stars and Population III stars
We suggest that the mass lost during the evolution of very massive stars may be dominated by optically thick, continuum-driven outbursts or explosions, instead of by steady line-driven winds. InExpand
A massive hypergiant star as the progenitor of the supernova SN 2005gl
TLDR
It is reported that the previously proposed object was indeed the progenitor star of SN 2005gl, likely a luminous blue variable that standard stellar evolution predicts should not have exploded in that state. Expand
