The News and Super Earth Kepler-22b

Yesterday, NASA confirmed another new exoplanet from the Kepler mission, Kepler-22b. From some of the headlines, you’d think it was time to pack your bags. The discovery of Kepler-22b is undeniably exciting, but there’s a lot we don’t know about this planet.

Intro to Astro – Confessions of a Novice Research Student

I’m a fourth year undergraduate from the University of Southampton, UK, studying for my masters at the Harvard-Smithsonian Centre for Astrophysics. With my summer reading completed, and a new exoplanet waiting to be discovered, I stepped off the plane into Boston Logan Int. this September and eagerly exchanged a drizzly English summer for a beautiful New English Autumn.

Planets, stars, and their magnetic interaction

Planets, stars, and their magnetic interaction

This paper investigates the interaction between close-in (semimajor axis a<0.15AU) massive planets (a.k.a. “hot Jupiters'') and their host (late-type) stars. Two possible mechanisms for interaction are tidal and magnetic, with the focus of this paper being the latter. The pioneering work on the topic of stellar activity enhancement (such as dark spots, faculae, etc) due to planet interaction is by Cuntz et al. (2000). You can see related contributions about stellar activity on previous astrobites posts.
