Formation of cold giant planets around late M dwarfs via core accretion and the fate of inner rocky worlds

Astronomy & Astrophysics
Context. Modeling how cold giant planets form around M dwarfs remains a challenge, both because their protoplanetary disks can lack sufficient mass and because such planets are expected to migrate inward while interacting with the disk.

The Gasing Pangkah Collaboration. I. Asteroseismic Identification and Characterization of a Rapidly Rotating Engulfment Candidate

The Astrophysical Journal
We report the discovery and characterization of TIC 350842552 (“Zvrk”), an apparently isolated, rapidly rotating ( P _rot ∼ 99 days) red giant observed by TESS in its southern Continuous Viewing Zone.

The Decline and Fall of ROME. V. A Preliminary Search for Star-disrupted Planet Interactions and Coronal Activity at 5 GHz among White Dwarfs within 25 pc

The Astrophysical Journal
The recent discovery of planetesimals orbiting white dwarfs has renewed interest in the final chapters of the evolution of planetary systems. Although observational and theoretical studies have examined the dynamical evolution of these systems, studies ...

Star-planet interactions: planetary orbital evolution and Engulfment

, 2016
L'orbite d'une planète peut changer significativement au cours du temps. À cause des forces de marée entre l'étoile et la planète, des échanges entre le moment angulaire orbital de la planète et le moment angulaire rotationnel de l'étoile peuvent survenir.
