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.

In this episode, Michelle and Nicole dissect 5 papers, and accidentally find a common theme: disks! Whether in low mass galaxies, giant low surface brightness galaxies, the rotation curves of spirals or the natal environment of planetary systems, disks really are all around us. They also discuss the differences in chemistries between globular clusters that have been accreted or formed in-situ, just for a little bit of balance.
