The evolution of Red Supergiant mass-loss rates
Emma R. Beasor, Ben Davies
The fate of massive stars with initial masses >8M depends largely on the mass-loss rate (\mdot ) in the end stages of their lives. Red supergiants (RSGs) are the direct pro…
The Initial Masses of the Red Supergiant Progenitors to Type-II Supernovae
Ben Davies, Emma Beasor
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 b…
Red Supergiants as Cosmic Abundance Probes: massive star clusters in M83, and the mass-metallicity relation of nearby galaxies
Ben Davies, Rolf-Peter Kudritzki, Carmela Lardo +6
We present an abundance analysis of seven super-star clusters in the disk of M83. The near-infrared spectra of these clusters are dominated by Red Supergiants, and the spectral sim…
The evolution of red supergiants to supernovae
Emma R. Beasor, Ben Davies
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…
