Making Extrasolar Planets From Solar Systems Via Dynamical Interactions

, 2010
Most stars form in some sort of stellar cluster or association. In such environments the number density of stars is much higher than in the solar neighbourhood, which means that close encounters between stars may be relatively common.

HD 715 b, a Warm Jupiter Orbiting a Massive Subgiant Discovered from a Single TESS Transit

The Astronomical Journal
Transiting warm Jupiters orbiting bright stars are scarcely known, but a substantial number of these planets have been uncovered by the TESS mission. In this work, we report the discovery and confirmation of a transiting warm Jupiter orbiting the bright (

Searching for GEMS: TOI-7149 b, an Inflated Giant Planet Causing a 12% Transit of a Fully Convective M-dwarf

The Astronomical Journal
We describe the discovery and characterization of TOI-7149 b, a 0.705 ± 0.075 M _J , 1.18 ± 0.045 R _J gas giant on a ∼2.65 days period orbit transiting an M4V star with a mass of 0.344 ± 0.030 M _⊙ and an effective temperature of 3363 ± 59 K. The planet

Transiting Jupiters around M Dwarfs Have Similar Masses to FGK Warm Jupiters

The Astrophysical Journal
This paper presents a comparative analysis of the bulk properties (mass and radius) of transiting giant planets (≳8 R _⊕ ) orbiting FGKM stars. Our findings suggest that the average mass of M-dwarf Jupiters is lower than that of their solar-type ...

Formation of Giant Planets by Gas Disk Gravitational Instability on Wide Orbits around Protostars with Varied Masses. II. Quadrupled Spatial Resolution and Beta Cooling

The Astrophysical Journal
Exoplanet demographics are sufficiently advanced to provide important constraints on theories of planet formation. While core and pebble accretion are preferred for rocky and icy planets, there appears to be a need for gas disk gravitational instability (
