Giant Planet Engulfment by Evolved Giant Stars: Light Curves, Asteroseismology, and Survivability

The Astrophysical Journal, 2023
About ten percent of Sun-like (1–2 M _⊙ ) stars will engulf a 1–10 M _J planet as they expand during the red giant branch (RGB) or asymptotic giant branch (AGB) phase of their evolution.

Case Studies of Habitable Trojan Planets in the System of HD 23079

, 2011
We investigate the possibility of habitable Trojan planets in the HD 23079 star-planet system. This system consists of a solar-type star and a Jupiter-type planet, which orbits the star near the outer edge of the stellar habitable zone in an orbit of low

A Survey for Massive Giant Planets in Debris Disks with Evacuated Inner Cavities [PDF]

, 2007
The commonality of collisionally replenished debris around main sequence stars suggests that minor bodies are frequent around Sun-like stars. Whether or not debris disks in general are accompanied by planets is yet unknown, but debris disks with large ...

Searching for GEMS: TOI-6383Ab, a Giant Planet Transiting an M3-dwarf Star in a Binary System

The Astronomical Journal
We report on the discovery of a transiting giant planet around the 3500 K M3-dwarf star TOI-6383A located 172 pc from Earth. It was detected by the Transiting Exoplanet Survey Satellite and confirmed by a combination of ground-based follow-up photometry ...

Self Similar Shocks in Atmospheric Mass Loss Due to Planetary Collisions

Atmosphere, 2020
We present a mathematical model for the propagation of the shock waves that occur during planetary collisions. Such collisions are thought to occur during the formation of terrestrial planets, and they have the potential to erode the planet’s atmosphere.

AMBER/VLTI observations of 5 giant stars [PDF]

, 2011
While the search for exoplanets around main sequence stars more massive than the Sun have found relatively few such objects, surveys performed around giant stars have led to the discovery of more than 30 new exoplanets.

COULD JUPITER OR SATURN HAVE EJECTED A FIFTH GIANT PLANET? [PDF]

, 2015
Models of the dynamical evolution of the early solar system that follow the dispersal of the gaseous protoplanetary disk have been widely successful in reconstructing the current orbital configuration of the giant planets. Statistically, some of the most

Formation of exoplanetary satellites by pull-down capture. [PDF]

, 2019
The large size and wide orbit of the recently announced exomoon candidate Kepler-1625b-i are hard to explain within traditional theories of satellite formation.

Detectability of giant planets in protoplanetary disks by CO emission lines

, 2010
In this paper we intend to provide an indirect method to detect Jovian planets by studying near infrared emission spectra originating in the protoplanetary disks around T Tauri stars.

GASEOUS MEAN OPACITIES FOR GIANT PLANET AND ULTRACOOL DWARF ATMOSPHERES OVER A RANGE OF METALLICITIES AND TEMPERATURES [PDF]

, 2014
We present new calculations of Rosseland and Planck gaseous mean opacities relevant to the atmospheres of giant planets and ultracool dwarfs. Such calculations are used in modeling the atmospheres, interiors, formation, and evolution of these objects ...
