Context. The increasing number of observed supernova events allows for finding the progenitor star even more frequently in archive images. In a few cases, the progenitor star is a yellow supergiant star. The estimated position in the Hertzsprung-Russell diagram of these stars is not compatible with the theoretical tracks of classical single-star models. Aims. According to several authors, the mass-loss rates during the red supergiant phase could be underestimated. We study the impact of an… Expand

The evolution of red supergiants to supernova in NGC 2100
The mass loss rates of red supergiants (RSGs) govern their evolution towards supernova and dictate the appearance of the resulting explosion. To study how mass-loss rates change with evolution weExpand
The evolution of red supergiants to supernovae
Abstract With red supergiants (RSGs) predicted to end their lives as Type IIP core collapse supernova (CCSN), their behaviour before explosion needs to be fully understood. Mass loss rates govern RSGExpand
Impact of mass-loss on the evolution and pre-supernova properties of red supergiants
The post main-sequence evolution of massive stars is very sensitive to many parameters of the stellar models. Key parameters are the mixing processes, the metallicity, the mass-loss rate and theExpand
The initial masses of the red supergiant progenitors to Type II supernovae
There are a growing number of nearby SNe for which the progenitor star is detected in archival pre-explosion imaging. From these images it is possible to measure the progenitor's brightness a fewExpand
The Luminosity Function of Red Supergiants in M31
The mass-loss rates of red supergiant stars (RSGs) are poorly constrained by direct measurements, and yet the subsequent evolution of these stars depends critically on how much mass is lost duringExpand

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
A new mass-loss rate prescription for red supergiants
Evolutionary models have shown the substantial effect that strong mass-loss rates (⁠M˙s) can have on the fate of massive stars. Red supergiant (RSG) mass-loss is poorly understood theoretically, andExpand
Abstract. Mass-loss rates are one of the most relevant parameters de-termining the evolution of massive stars. In particular, the rate atwhich the star loses mass during the red-supergiant (RSG)Expand
Evolution of blue supergiants and α Cygni variables: puzzling CNO surface abundances
A massive star can enter the blue supergiant region either evolving directly from the main-sequence, or evolving from a previous red supergiant stage. The fractions of the blue supergiants havingExpand

The effect of massive binaries on stellar populations and supernova progenitors
We compare our latest single and binary stellar model results from the Cambridge stars code to several sets of observations. We examine four stellar population ratios: the number of blue to redExpand

The progenitor of supernova 1993J: a stripped supergiant in a binary system?
SUPERNOVA 1993J in the spiral galaxy M81 is the brightest supernova since SN1987A and, like the latter, appears to be another 'peculiar' type II supernova. The available photometry1,2 of theExpand
The mass-loss rates of red supergiants and the de Jager prescription
Mass loss of red supergiants (RSG) is important for the evolution of massive stars, but is not fully explained. Several empirical prescriptions have been proposed, trying to express the mass-lossExpand

Supernovae from red supergiants with extensive mass loss
We calculate multicolour light curves (LCs) of supernovae (SNe) from red supergiants (RSGs) that have exploded within a dense circumstellar medium (CSM). Multicolour LCs are calculated by using theExpand
