We investigate the fundamental properties of core-collapse Supernova (SN) progenitors from single stars at solar meta llicity. For this purpose, we combine Geneva stellar evolutionary models with initial masses of Mini = 20− 120 M⊙ with atmospheric/wind models using the radiative transfer code CMFGEN. We provide synthetic photometry and high-resolution spectra of hot stars at t he pre-SN stage. For models with Mini = 9− 20 M⊙, we supplement our analysis using publicly available MARCS model… 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
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 ofExpand
The Galactic WC and WO stars: The impact of revised distances from Gaia DR2 and their role as massive black hole progenitors
Wolf-Rayet stars of the carbon sequence (WC stars) are an important cornerstone in the late evolution of massive stars before their core collapse. As core-helium burning, hydrogen-free objects withExpand
Testing massive star evolution, star-formation history and feedback at low metallicity : Spectroscopic analysis of OB stars in the SMC Wing
Stars which start their lives with spectral types O and early-B are the progenitors of core-collapse supernovae, long gamma-ray bursts, neutron stars, and black holes. These massive stars are theExpand
The evolution of massive stars and their spectra - I. A non-rotating 60 M⊙ star from the zero-age main sequence to the pre-supernova stage
For the first time, the interior and spectroscopic evolution of a massive star is analyzed from the zero-age main sequence (ZAMS) to the pre-supernova (SN) stage. For this purpose, we combinedExpand

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 oftenExpand
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
Observational Properties of Type Ib/c Supernova Progenitors in Binary Systems
In several recent observational studies of Type Ib/c supernovae (SNe Ib/c), the inferred ejecta masses have a peak value of 2.0–4.0 , in favor of the binary scenario for their progenitors rather thanExpand
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 toExpand
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 beenExpand

Context. In recent years, many very interesting observations have appeared concerning the positions of Wolf-Rayet (WR) stars in the Hertzsprung-Russell diagram (HRD), the number ratios of WR stars,Expand
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.Expand
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 inExpand
Stellar evolution with rotation - XIII. Predicted GRB rates at various Z

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
Core-collapse explosions of Wolf–Rayet stars and the connection to Type IIb/Ib/Ic supernovae

Mass loss from late-type WN stars and its Z-dependence: very massive stars approaching the Eddington limit
The mass loss from Wolf-Rayet (WR) stars is of fundamental importance for the final fate of massive stars and their chemical yields. Its Z-dependence is discussed in relation to the formation ofExpand
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 redExpand
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.
