How cold is Planet X?
Simple physical models can yield useful insights into the structure of planets in the outer Solar System.
The Case of the Missing Giants
Red giant stars are bright enough to see at the center of our galaxy, but they are missing. A new study puts stars in a wind tunnel to explore a possible way to dim the lights.
Creating a Cosmic Inventory of Rocky Planets
Combining cosmology, galaxy formation, and exoplanet science together, can we calculate the number of rocky planets in the entire universe?
Uncovering planets and stellar activity using only radial velocities
How do we model stellar activity to disentangle planet signals from stellar activity using only RVs?
The bouncing barrier of silicates and ices
Planets are km-size bodies, but it is particularly puzzling how solid grains have grown to sizes beyond cm to m. Water ices can improve the sticking of such grains, but does this imply that ices from other molecules improve the sticking as well?
An Overview of the Extreme Solar Systems III Conference
The third Extreme Solar System conference was held between Nov 29 to Dec 4th, in Kona, Hawaii, on the 20th anniversary of the first exoplanet detection around a main sequence star. This astrobite gives a brief overview of the conference.
