Rare Stellar Populations in the Magellanic Clouds: Identification of Super-Asymptotic Giant Branch Star and Yellow Supergiant Binary Candidates
… characterize multiple new populations of massive stars in rare or elusive phases of stellar evolution---thereby demonstrating the power of large surveys and systematic observation campaigns to constrain models of massive star evolution. First, I investigate the true nature of the peculiar star …

Atmospheric temperature structure in the RoAp stars
The rapidly oscillating Ap (roAp) stars are a sub-group of the chemically peculiar stars of class 2 (CP2), which are characterised by peculiar spectra and anomalously strong lines of Sr, Cr, Eu and other rare earth elements. They have strong global dipole magnetic fields with effective strengths of …

Disentangling the chemodynamical history of the Milky Way disc with asteroseismology and spectroscopy
… we can observe millions of its individual stars whose kinematics and chemical composition are records of the evolution of our Galaxy. Thanks to the advent of multi-object spectroscopic surveys, we can systematically study stellar populations in a much larger volume of the Milky Way. While …
