Metallicity of the Massive Protoplanets Around HR 8799 If Formed by Gravitational Instability

, 2009
The final composition of giant planets formed as a result of gravitational instability in the disk gas depends on their ability to capture solid material (planetesimals) during their 'pre-collapse' stage, when they are extended and cold, and contracting ...

Giant Planet Formation by Core Accretion

, 2007
We present a review of the standard paradigm for giant planet formation, the core accretion theory. After an overview of the basic concepts of this model, results of the original implementation are discussed.

The Architectural Design Rules of Solar Systems based on the New Perspective

, 2009
On the basis of the Lunar Laser Ranging Data released by NASA on the Silver Jubilee Celebration of Man Landing on Moon on 21st July 1969-1994, theoretical formulation of Earth-Moon tidal interaction was carried out and Planetary Satellite Dynamics was ...

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 ...
