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 establish which star was the progenitor have led to uncertainties, however. Here we use spatial and spectroscopic information from International Ultraviolet Explorer (IUE) spectra in the range 1,150–1,950Å to demonstrate that Sk–69 202, the star coinciding positionally with the Large Magellanic… 

Supernova Progenitors Observed with HST

To understand the relevance of supernovae and to enable their use as probes of stellar evolution throughout time, it is necessary to determine their stellar origins. I describe the direct

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


We have obtained limited photometric and spectroscopic data for supernova (SN) 2008bk in NGC 7793, primarily at ≳ 150 days after explosion. We find that it is a Type II-Plateau (II-P) SN that most

On the Progenitor of the Type II Supernova 2004et in NGC 6946

Supernova (SN) 2004et is the eighth historical SN in the nearby spiral galaxy NGC 6946. Here we report on early photometric and spectroscopic monitoring of this object. SN 2004et is a Type II event,

SN 2009E: a faint clone of SN 1987A

Context. 1987A-like events form a rare sub-group of hydrogen-rich core-collapse supernovae that are thought to originate from the explosion of blue supergiant stars. Although SN 1987A is the best

The Disappearance of the Progenitors of Supernovae 1993J and 2003gd

Using images from the Hubble Space Telescope and the Gemini Telescope, the disappearance of the progenitors of two type II supernovae (SNe) are confirmed and the presence of other stars associated with them is evaluated and it is confirmed that these two supernova were produced by red supergiants.

The direct identification of SN progenitors in existing pre-explosion images, particularly those obtained through serendipitous imaging of nearby galaxies by the Hubble Space Telescope are described.

The direct identification of core-collapse supernova progenitors

To place core-collapse supernovae (SNe) in context with the evolution of massive stars, it is necessary to determine their stellar origins. I describe the direct identification of SN progenitors in


A set of hydrodynamical models based on stellar evolutionary progenitors is used to study the nature of SN 2011dh. Our modeling suggests that a large progenitor star—with R ∼ 200 R☉—is needed to

The supernova 1987A in the Large Magellanic Cloud

Two years after the discovery of supernova 1987A in the Large Magellanic Cloud the huge amount of new and exciting information is still being analysed by astronomers and astrophysicists all over the
