Extreme Makeover: Exoplanet Edition

Extreme Makeover: Exoplanet Edition

The past 20 years of exoplanet discovery have unveiled many peculiar planets in the Milky Way. Today’s paper investigates if two classes of these odd planets could be the same planet at different points in their evolutionary history – if hot Jupiters can transform into super-Earths!

Capella’s Secrets

Capella’s Secrets

While you might expect astronomers to already have a complete understanding of bright stars easily visible to the naked eye like Capella, observations have historically failed to line up with stellar evolution theories. Today’s paper revisits Capella with a new suite of observations to finally uncover some of its secrets.

A Cepheid Pulsator in an Eccentric Binary

Cepheids’ pulsing brightness variations happen because the star’s temperature and radius is changing, and they occupy a unique niche of stellar evolution. We can learn a lot about what is physically happening inside stars during this tumultuous time through close observations. Or rather, we could learn a lot about what happens inside Cepheid variable stars, if only we knew their masses.
