Are more massive stars more likely to have planets? Read on to find out…
The International Astronomical Union wants you to name a planet! While you ponder what to submit as a planet name, read on to learn the history and politics that led to this exciting opportunity.
The answer to the above question, according to a new analysis of data from NASA’s Kepler mission, may be roughly one-third.
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).
