A Spectroscopic Hunt for Post-Red Supergiants in the Large Magellanic Cloud II: Turbulent Line Broadening in the Spectra of LMC Yellow Supergiants
Trevor Z. Dorn-Wallenstein, Kaitlyn M. Chen, Samantha C. Wu +4
Massive stars in the Hertzsprung gap are a mixed population of objects in short-lived evolutionary phases: yellow supergiants (YSGs) evolving towards the red supergiant (RSG) phase…
A Spectroscopic Hunt for Post-Red Supergiants in the Large Magellanic Cloud I: Preliminary Results
Kaitlyn M. Chen, Trevor Z. Dorn-Wallenstein
Yellow supergiants (YSGs) are rare and poorly understood, and studying them is critical to constraining massive star evolution. We obtained flux-calibrated Magellan Inamori Kyocera…
Physical Properties of 5,000 Cool LMC Supergiants with Gaia XP Spectra: A Detailed Portrait of the Upper HR Diagram Hints at Missing Supernova Progenitors
Trevor Z. Dorn-Wallenstein, Kathryn F. Neugent, Emily M. Levesque
Characterizing the physical properties of cool supergiants allows us to probe the final stages of a massive star's evolution before it undergoes core collapse. Despite their import…
Photometric detection of internal gravity waves in upper main-sequence stars. III. Comparison of amplitude spectrum fitting and Gaussian process regression using celerite2
Dominic M. Bowman, Trevor Z. Dorn-Wallenstein
Studies of massive stars using space photometry have revealed that they commonly exhibit stochastic low-frequency (SLF) variability. This has been interpreted as being caused by in…
The Properties of Fast Yellow Pulsating Supergiants: FYPS Point the Way to Missing Red Supergiants
Trevor Z. Dorn-Wallenstein, Emily M. Levesque, James R. A. Davenport +3
Fast yellow pulsating supergiants (FYPS) are a recently-discovered class of evolved massive pulsator. As candidate post-red supergiant objects, and one of the few classes of pulsat…
Testing Evolutionary Models with Red Supergiant and Wolf-Rayet Populations
Philip Massey, Kathryn F. Neugent, Trevor Z. Dorn-Wallenstein +3
Despite the many successes that modern massive star evolutionary theory has enjoyed, reproducing the apparent trend in the relative number of red supergiants (RSGs) and Wolf-Rayet…
