By comparing the properties of red supergiant (RSG) supernova (SN) progenitors to those of field RSGs, it has been claimed that there is an absence of progenitors with luminosities L above log (L/L⊙) > 5.2. This is in tension with the empirical upper luminosity limit of RSGs at log (L/L⊙) = 5.5, a result known as the ‘RSG problem’. This has been interpreted as an evidence for an upper mass threshold for the formation of black holes. In this paper, we compare the observed luminosities of RSG SN…

Revisiting the progenitor of the low-luminosity type II-plateau supernova, SN 2008bk
The availability of updated model atmospheres for red supergiants and improvements in single and binary stellar evolution models, as well as previously unpublished data prompted us to revisit the
The temperatures of red supergiants in low-metallicity environments
The temperatures of red supergiants (RSGs) are expected to depend on metallicity (Z) in such a way that lower-Z RSGs are warmer. In this work, we investigate the Z-dependence of the Hayashi limit by
‘On the red supergiant problem’: a rebuttal, and a consensus on the upper mass cut-off for II-P progenitors
The `Red Supergiant Problem' describes the claim that the brightest Red Supergiant (RSG) progenitors to type II-P supernovae are significantly fainter than RSGs in the field. This mismatch has been
Theoretical investigation of the Humphreys–Davidson limit at high and low metallicity
Context. Current massive star evolution grids are not able to simultaneously reproduce the empirical upper luminosity limit of red supergiants, the Humphrey–Davidson (HD) limit, nor the blue-to-red
Superadiabaticity and the metallicity independence of the Humphreys–Davidson limit
The Humphreys–Davidson (HD) limit sets the boundary between evolutionary channels of massive stars that end their lives either as the red supergiants (RSGs) or as the hotter blue supergiants (BSGs)
An Exceptional Dimming Event for a Massive, Cool Supergiant in M51
We present the discovery of an exceptional dimming event in a cool supergiant star in the Local Volume spiral M51. The star, dubbed M51-DS1, was found as part of a Hubble Space Telescope (HST) search
Constraining red supergiant mass-loss prescriptions through supernova radio properties
Supernova properties in radio strongly depend on their circumstellar environment and they are an important probe to investigate the mass loss of supernova progenitors. Recently, core-collapse
The excess of cool supergiants from contemporary stellar evolution models defies the metallicity-independent Humphreys–Davidson limit
The Humphreys–Davidson (HD) limit empirically defines a region of high luminosities (log10(L/L⊙) ≳ 5.5) and low effective temperatures ($T_{\rm eff} \lesssim 20 \, {\rm kK}$) on the
Progenitor properties of type II supernovae: fitting to hydrodynamical models using Markov chain Monte Carlo methods
The progenitor and explosion properties of type II supernovae (SNe II) are fundamental to understand the evolution of massive stars. Special interest has been given to the range of initial masses of
The Masses of Supernova Remnant Progenitors in NGC 6946
