Planet-Planet Scattering Explains the Mass-Eccentricity Relation of Warm Jupiters
Jiayin Dong, Eve J. Lee, Eiichiro Kokubo +2
Warm giant planets with orbital periods of tens of days exhibit a positive correlation between mass and eccentricity. We interpret this trend as the outcome of planet-planet scatte…
Observational Signatures of Circumstellar Gas Tori Formed by Planetary Mass-Loss from Close-In Exoplanets
Ethan Schreyer, Ruth Murray-Clay
Close-in exoplanets with H/He atmospheres often undergo hydrodynamic escape. In extreme cases, it is hypothesized that the mass loss can be high enough for the escaping planetary m…
The Exospace Weather Frontier
R. O. Parke Loyd, Evgenya L. Shkolnik, Joseph Lazio +26
Space weather is among the most powerful and least understood forces shaping planetary atmospheres. In our Solar System, we observe its effects directly: atmospheric escape, chemic…
Evolution of the ZTF SLRN-2020 star-planet merger
Ricardo Yarza, Morgan MacLeod, Benjamin Idini +2
We model the optical and infrared transient ZTF SLRN-2020, previously associated with a star-planet merger. We consider the scenario in which orbital decay via tidal dissipation le…
