Exoplanet Occurrence Rate with Age for FGK Stars in Kepler

The Astronomical Journal
We measure the exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1–17 DR25 Kepler data. We employ Kepler's pipeline detection efficiency to correct for the expected number of

Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System

The Astronomical Journal, 2023
The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.

Impact of Stellar Dynamics on the Frequency of Giant Planets in Close Binaries [PDF]

, 2006
Hostile tidal forces may inhibit the formation of Jovian planets in binaries with semimajor axes of ≾50 AU, binaries that might be called "close" in this context. As an alternative to in situ planet formation, a binary can acquire a giant planet when one

Illusion and Reality in the Atmospheres of Exoplanets

, 2017
The atmospheres of exoplanets reveal all their properties beyond mass, radius, and orbit. Based on bulk densities, we know that exoplanets larger than 1.5 Earth radii must have gaseous envelopes, hence atmospheres.

Tidal synchronization of close-in satellites and exoplanets: II. Spin dynamics and extension to Mercury and exoplanet host stars [PDF]

Celestial Mechanics and Dynamical Astronomy, 2015
This paper deals with the application of the creep tide theory (Ferraz-Mello, CeMDA 116, 109, 2013) to the rotation of close-in satellites, Mercury, close-in exoplanets and their host stars. The solutions show two extreme cases: close-in giant gaseous planets, with fast relaxation (low viscosity) and satellites and Earth-like planets, with slow ...

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 ...

Dynamical Study of the Exoplanet Host Binary System HD 106515 [PDF]

Publications of the Astronomical Society of Australia, 2017
AbstractHD 106515 AB (STF1619 AB) is a high common proper motion and common radial velocity binary star system composed of two G-type bright stars located at 35 pc and separated by about 7 arcsec. This system was observed by theHipparcossatellite with a precision in distance and proper motion of 3 and 2%, respectively.

Classification of Planetary Motion around Super-Jupiters and Brown Dwarfs

Universe
We investigate the orbital dynamics of an exosystem consisting of a solar-mass host star, a transiting body, and an Earth-size exoplanet within the framework of the generalized three-body problem.

Boundary Layers of Circumplanetary Disks around Spinning Planets. I. Effects of Rossby Waves

The Astrophysical Journal, 2023
Gas giant planets are believed to accrete from their circumplanetary disks (CPDs). The CPDs usually involve accretion through the boundary layer (BL) in the vicinity of planets. Prior studies have concentrated on the BL of nonspinning planets.
