Spin Dynamics of Extrasolar Giant Planets in Planet–Planet Scattering [PDF]
The Astrophysical Journal, 2021 Abstract Planet–planet scattering best explains the eccentricity distribution of extrasolar giant planets, and past literature showed that the orbits of planets evolve due to planet–planet scattering. This work studies the spin evolution of planets in planet–planet scattering in two-planet systems.

Atmosphere loss in planet–planet collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Many of the planets discovered by the Kepler satellite are close orbiting super-Earths or mini-Neptunes. Such objects exhibit a wide spread of densities for similar masses. One possible explanation for this density spread is giant collisions stripping planets of their atmospheres.

Scientific American, 2006 A planet is an end product of disk accretion around a primary star or substar. I quantify this definition by the degree to which a body dominates the other masses that share its orbital zone. Theoretical and observational measures of dynamical dominance reveal a gap of four to five orders of magnitude separating the eight planets of our solar system ...

A new family of planets? “Ocean-Planets” [PDF]
Icarus, 2004 A new family of planets is considered which is between rochy terrestrial planets and gaseous giant ones: "Ocean-Planets". We present the possible formation, composition and internal models of these putative planets, including that of their ocean, as well as their possible Exobiology interest.

Dynamical Outcomes of Planet‐Planet Scattering [PDF]
The Astrophysical Journal, 2008 Observations in the past decade have revealed extrasolar planets with a wide range of orbital semimajor axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations.

, 2007 We review the interior structure and evolution of Jupiter, Saturn, Uranus and Neptune, and giant exoplanets with particular emphasis on constraining their global composition. Compared to the first edition of this review, we provide a new discussion of the atmospheric compositions of the solar system giant planets, we discuss the discovery of ...

Tilting Planets during Planet Scattering [PDF]
The Astrophysical Journal Letters, 2021 Abstract Observational constraints on planetary spin axis have recently become possible, and they have revealed a system that favors large spin-axis misalignment, low stellar spin–orbit misalignment, and high eccentricity. To explain the origin of such systems, we propose a mechanism that could tilt the planetary spin axis during planet ...

Applicability study of four atmospheric correction methods in the remote sensing of lake water color
Geocarto International, 2023 Due to the complexity of spectral characteristics for inland lake water, high-precision atmospheric correction methods play an essential role in remote sensing.

Remote Sensing, 2021 We analyzed the Corine Land Cover 2018 (CLC2018) dataset to reveal the correspondence between land cover categories of the CLC and the spectral information of Landsat-8, Sentinel-2 and PlanetScope images.
