In this episode, Michelle and Payel both dissect interesting results from varying stars, including follow up on Betelgeuse’s elusive companion. They also talk about the imprints of digested and transiting stars on their hosts spectra, and an unusual lensing signal that could pose difficult questions for warm and cold dark matter.
