The symphony of pulsations and binarity among massive stars using HERMES spectroscopy and TESS photometry
The episode discusses a paper analyzing massive stars using HERMES spectroscopy and TESS photometry to study pulsations and binarity. The research found that over 93% of the sample shows photometric variation, with 82% exhibiting pulsations. At least 14% of stars show evidence of binarity, providing a large database for testing stellar evolution models.
