A hidden reservoir of multi-planet systems?
Today, let’s take a look at the connection between planetary system types and host star metallicities.
How can planets be heavier than the disks that formed them?
Planets form from protoplanetary disks. How they can be heavier on average than the disks is questioning our theories of planet formation.
How Many Planets Will We Find Around White Dwarfs?
We know that white dwarfs have planets, but there are very few that we have detected directly. An upcoming survey may change that.
Some Like it Hot
Let’s take a closer look at planet formation via core accretion. Does the accretion physics let us decipher other secrets of a planet long after the accretion is over?
Directly measuring the mass of an imaged planet
Extremely accurate measurements of the position of β Pictoris from the Hipparcos and Gaia satellites allow the direct measurement of the mass of the imaged planet β Pic b.
Our M-dwarf Models Just Aren’t Good Enough
We need to know the radii of M-dwarfs to study their exoplanets, and the models aren’t much help.
