The latest new paper is available from UW Massive Stars research group! Led by former UW undergrad (and current grad student at Arizona State University!) Tzvetelina Dimitrova (who was advised by recent group PhD graduate Dr. Kathryn Neugent!), the paper uses archival near-IR photometry to identify bright red supergiants in the low-metallicity Local Group galaxy NGC 6822. We previously obtained spectra of a smaller sample of RSGs in this galaxy, but Tzvetelina’s comprehensive survey of these stars makes it possible to probe membership criteria in this galaxy and determine physical properties for the full sample that can be compared to stellar evolution models.

The paper is in press with the Astronomical Journal; for now you can check it out on arXiv!
