  author={J. Eldridge and M. Fraser and S. Smartt and J. Maund and R. Crockett},
The progenitors of many Type II core-collapse supernovae (SNe) have now been identified directly on pre-discovery imaging. Here, we present an extensive search for the progenitors of Type Ibc SNe in all available pre-discovery imaging since 1998. There are 12 Type Ibc SNe with no detections of progenitors in either deep ground-based or Hubble Space Telescope archival imaging. The deepest absolute BVR magnitude limits are between −4 and −5 mag. We compare these limits with the observed Wolf… Expand
A Wolf–Rayet-like progenitor of SN 2013cu from spectral observations of a stellar wind
Wolf–Rayet-like wind signatures are identified, suggesting a progenitor of the WN(h) subclass (those WRSs with winds dominated by helium and nitrogen, with traces of hydrogen), consistent with recent theoretical predictions. Expand

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. Expand

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. Expand
The radial distribution of supernovae compared to star formation tracers
Given the limited availability of direct evidence (pre-explosion observations) for supernova (SN) progenitors, the location of supernovae (SNe) within their host galaxies can be used to set limits onExpand
Core-collapse supernovae and their progenitors
Dedicated SN searches started over 100 years ago. Over that time, astronomers have collected large sets of observational data. They have developed detailed classification and achieved generalExpand
The expansion of stripped-envelope stars: Consequences for supernovae and gravitational-wave progenitors
Massive binaries that merge as compact objects are the progenitors of gravitational-wave sources. Most of these binaries experience one or more phases of mass transfer, during which one of the starsExpand
Host Galaxies of Type Ic and Broad-lined Type Ic Supernovae from the Palomar Transient Factory: Implications for Jet Production
Unlike the ordinary supernovae (SNe) some of which are hydrogen and helium deficient (called Type Ic SNe), broad-lined Type Ic SNe (SNe Ic-bl) are very energetic events, and all SNe coincident withExpand
The explosive life of massive binaries
Massive stars are born predominantly as members of binary (or higher multiplicity) systems, and the presence of a companion can significantly alter their life and final fate. Therefore, any observedExpand
We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral eld spectroscopy (IFS) techniques, which is an extension of the work described in Kuncarayakti et al.Expand
The Impact of Interacting Binary Stars on Core-collapse Supernovae and Emission Nebulae
The evolution of binary-star systems vary from that of single stars as they can interact with their companions. This leads to mass loss, mass gain, or stellar mergers. We now know that most massiveExpand
