The potential of red supergiants as extragalactic abundance probes at low spectral resolution
Red supergiants (RSGs) are among the brightest stars in the local Universe, making them ideal candidates with which to probe the properties of their host galaxies. However, current quantitative spectroscopic techniques require spectral resolutions of R≳ 17 000, making observations of RSGs at distances greater than 1 Mpc unfeasible. Here …
