Mass-loss rates of cool evolved stars in M33 galaxy
Atefeh Javadi, Jacco Th. van Loon
TL;DR
This study measures dust and gas mass-loss rates from pulsating AGB stars and RSGs in the galaxy M33, providing insights into stellar evolution and galaxy enrichment processes.
Contribution
It presents the first comprehensive near-infrared monitoring of mass-loss rates of evolved stars across M33's stellar disc.
Findings
Quantified dust and gas mass-loss rates for AGB stars and RSGs.
Mapped the distribution of mass-loss across M33.
Enhanced understanding of stellar feedback in galaxy evolution.
Abstract
We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope (UKIRT), of the Local Group spiral galaxy M33 (Triangulum). In this paper, we present the dust and gas mass-loss rates by the pulsating Asymptotic Giant Branch (AGB) stars and red supergiants (RSGs) across the stellar disc of M33.
