Abstract Over the last 15 years, the supernova community has endeavoured to directly identify progenitor stars for core-collapse supernovae discovered in nearby galaxies. These precursors are often visible as resolved stars in high-resolution images from space-and ground-based telescopes. The discovery rate of progenitor stars is limited by the local supernova rate and the availability and depth of archive images of galaxies, with 18 detections of precursor objects and 27 upper limits.

Abstract Here are reviewed the insights from observations at optical and infrared wavelengths for low mass limits above which stars do not seem to end as luminous supernovae. These insights are: (1)

Core-collapse supernova progenitor constraints using the spatial distributions of massive stars in local galaxies

We study the spatial correlations between the H$\alpha$ emission and different types of massive stars in two local galaxies, the Large Magellanic Cloud (LMC) and Messier 33. We compare these to

Progenitor constraints for core-collapse supernovae from Chandra X-ray observations

The progenitors of hydrogen-poor core-collapse supernovae (SNe) of types Ib, Ic and IIb are believed to have shed their outer hydrogen envelopes either by extremely strong stellar winds,

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

The very young resolved stellar populations around stripped-envelope supernovae

The massive star origins for Type IIP supernovae (SNe) have been established through direct detection of their red supergiants progenitors in pre-explosion observations; however, there has been


Using resolved stellar photometry measured from archival Hubble Space Telescope imaging, we generate color–magnitude diagrams of the stars within 50 pc of the locations of historic core-collapse

Measurement of the Core-collapse Progenitor Mass Distribution of the Small Magellanic Cloud

The physics of core-collapse (CC) supernovae (SNe) and how the explosions depend on progenitor properties are central questions in astronomy. For only a handful of SNe, the progenitor star has been

The Masses of Supernova Remnant Progenitors in M83

We determine the ages of the young, resolved stellar populations at the locations of 237 optically identified supernova remnants in M83. These age distributions put constraints on the progenitor

Core-collapse supernovae ages and metallicities from emission-line diagnostics of nearby stellar populations

Massive stars are the main objects that illuminate H II regions and they evolve quickly to end their lives in core-collapse supernovae (CCSNe). Thus it is important to investigate the association



The death of massive stars – I. Observational constraints on the progenitors of Type II-P supernovae

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

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

A Search for Core‐Collapse Supernova Progenitors in Hubble Space Telescope Images

Identifying the massive progenitor stars that give rise to core‐collapse supernovae (SNe) is one of the main pursuits of supernova and stellar evolution studies. Using ground‐based images of recent,

Mass limits for the progenitor star of supernova 2001du and other Type II-P supernovae

The supernova SN 2001 du was discovered in the galaxy NGC 1365 at a distance of 19 ′ 2 Mpc, and is a core-collapse event of Type II-P. Images of this galaxy, of moderate depth, have been taken with

The Progenitor of Supernova 1993J Revisited

From Hubble Space Telescope images with 0 .″05 resolution, we identify four stars brighter than V = 25 mag within 2 .″5 of SN 1993J in M81, which contaminated previous ground‐based brightness

Progenitors of supernova Ibc: a single Wolf-Rayet star as the possible progenitor of the SN Ib iPTF13bvn

Core-collapse supernova (SN) explosions mark the end of the tumultuous life of massive stars. Determining the nature of their progenitors is a crucial step towards understanding the properties of

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.

The Nature of the Progenitor of the Type II-P Supernova 1999em

The masses and the evolutionary states of the progenitors of core-collapse supernovae (SNe) are not well constrained by direct observations. Stellar evolution theory generally predicts that massive

Progenitor mass constraints for core-collapse supernovae from correlations with host galaxy star formation⋆

Using Hemission as a tracer of on-going (<16 Myr old) and near-UV emission as a tracer of recent (16-100 Myr old) star formation, we present constraints on the properties of core- collapse supernova

Observed Fractions of Core-Collapse Supernova Types and Initial Masses of their Single and Binary Progenitor Stars

We analyse the observed fractions of core-collapse supernova (SN) types from the Lick Observatory Supernova Search (LOSS), and we discuss the corresponding implications for massive star evolution.
