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…

Automated Spectroscopic Wavelength Calibration using Dynamic Time Warping
James R. A. Davenport, Francisca Chabour Barra, K. Azalee Bostroem +14
Here we present an automated method for obtaining wavelength calibrations for one-dimensional spectra, using Dynamic Time Warping (DTW). DTW is a flexible and well-understood algor…

Kalkayotl 2.0 Bayesian phase-space modelling of star-forming regions, stellar associations, and open clusters
J. Olivares, H. Bouy, Trevor Z. Dorn-Wallenstein +1
Context: Star-forming regions, stellar associations, and open clusters are fundamental stellar systems where predictions from star-formation theories can be robustly contrasted wit…
