Cool, hazy exoplanets might look a lot like Saturn’s moon Titan. Today’s post explores the possible atmospheres of exo-Titans around a variety of host stars.
Mini-Neptunes are among the most common type of planet in the galaxy. Are they as easy to build as we might think?
The light from a star is not constant, it varies as the layers of hot material move back and forth, clump and disperse. Most of these vibrations are visible, detectable, and well understood. But some bizarre new vibration is happening in stars, for which we have no clear path to an explanation.
We can precisely measure chemical abundances for stars. This offers an intriguing possibility that we may, in the near future, start using these measurements to know more about the insides of rocky planets orbiting them.
Planets that do not transit are very difficult for Kepler to find. The authors of today’s paper are not intimidated by that and find 60 non-transiting Hot Jupiters unknowingly detected by Kepler anyway.
For life as we know it, atmospheric composition plays a huge part in planetary habitability. Today we explore a theoretical framework for characterizing and predicting planetary atmospheres, and how that framework can help in the search for Earth-like life on planets beyond our own.
