A massive hypergiant star as the progenitor of the supernova SN 2005gl

@article{Galyam2009AMH,  title={A massive hypergiant star as the progenitor of the supernova SN 2005gl},  author={Avishay Gal-yam and Douglas C. Leonard},  journal={Nature},  year={2009},  volume={458},  pages={865-867},  url={https://api.semanticscholar.org/CorpusID:4392537}}
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.

Massive star evolution: luminous blue variables as unexpected supernova progenitors

Stars more massive than about 8 Mend their lives as a supernova (SN), an event of fundamental importance Universe-wide. Theoretically, these stars have been expected to be either at the red…

The Type IIn Supernova SN 2010bt: The Explosion of a Star in Outburst

It is well known that massive stars (M > 8 M☉) evolve up to the collapse of the stellar core, resulting in most cases in a supernova (SN) explosion. Their heterogeneity is related mainly to different…

Recent efforts to predict the nature of stars before death by performing coupled stellar evolution and atmosphere modelling of single stars in the pre-SN stage are reviewed, and the detectability of SN Ibc progenitors is assessed.

Type Ibn Supernovae May not all Come from Massive Stars

Because core-collapse supernovae are the explosions of massive stars, which have relatively short lifetimes, they occur almost exclusively in galaxies with active star formation. On the other hand,…

THE MASSIVE PROGENITOR OF THE TYPE II-LINEAR SUPERNOVA 2009kr

We present early-time photometric and spectroscopic observations of supernova (SN) 2009kr in NGC 1832. We find that its properties to date support its classification as Type II-linear (SN II-L), a…

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 mass…

Identifying Supernova Progenitors and Constraining the Explosion Channels

Abstract Connecting the endpoints of massive star evolution with the various types of core-collapse supernovae (SNe) is ultimately the fundamental puzzle to be explored and solved. We can assemble…

Modeling the remnants of core-collapse supernovae from luminous blue variable stars

Context. Luminous blue variable stars (LBVs) are massive evolved stars that suffer sporadic and violent mass-loss events. They have been proposed as the progenitors of some core-collapse supernovae…

Astrophysics: Windy stars that go with a bang

The detection of strong emission lines in early spectra from the type IIb supernova SN 2013cu that are consistent with a Wolf–Rayet star as progenitor are reported, suggesting that these massive stars do end their lives as supernovae.

On luminous blue variables as the progenitors of core-collapse supernovae, especially Type IIn supernovae

Luminous blue variable (LBV) stars are very massive, luminous, unstable stars that suffer frequent eruptions. In the last few years, these stars have been proposed as the direct progenitors of some…

A giant outburst two years before the core-collapse of a massive star

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.

Pulsational pair instability as an explanation for the most luminous supernovae

It is reported that the brightest supernovae in the modern Universe arise from collisions between shells of matter ejected by massive stars that undergo an interior instability arising from the production of electron–positron pairs.

The progenitors of many type II core-collapse supernovae have now been identified directly on pre-discovery imaging. Here we present an extensive search for the progenitors of type Ibc supernovae in…

One of the reasons why the bright supernova SN1987A is of such importance is the fact that its proximity would allow for the first time, the identification of a supernova progenitor star. Attempts to…

Identification of the Red Supergiant Progenitor of Supernova 2005cs: Do the Progenitors of Type II-P Supernovae Have Low Mass?

The stars that end their lives as supernovae (SNe) have been directly observed in only a handful of cases, mainly because of the extreme difficulty of identifying them in images obtained prior to the…

Detection of a Red Supergiant Progenitor Star of a Type II-Plateau Supernova

The discovery of a red supergiant star that exploded as supernova 2003gd in the nearby spiral galaxy M74 confirms both stellar evolution models and supernova theories predicting that cool red supergiants are the immediate progenitor stars of type II–plateau supernovae.

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. In…
