The California-Kepler Survey. III. A Gap in the Radius Distribution of Small Planets [PDF]
, 2017 The size of a planet is an observable property directly connected to the physics of its formation and evolution. We used precise radius measurements from the California-Kepler Survey to study the size distribution of 2025 Kepler planets in fine detail ...

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.

Progress in Earth and Planetary Science, 2023 The thermal structure of subduction zones is fundamental to our understanding of the physical and chemical processes that occur at active convergent plate margins. These include magma generation and related arc volcanism, shallow and deep seismicity, and

Feasibility Assessment and Implementation of Integrated Management of The West Coast of The Mazandran Province According to the ICZM [PDF]
مدیریت نوآوری و راهبردهای عملیاتی, 2021 Purpose: Integrated coastal zone management (ICZM) is the primary way to solve environmental problems. In addition, many countries in the world attempt to provide human needs to coastal region services to reach the natural border of these zones.

Temperate Earth-sized planets transiting a nearby ultracool dwarf star [PDF]
Nature, 2016 Star-like objects with effective temperatures of less than 2,700 kelvin are referred to as ‘ultracool dwarfs’. This heterogeneous group includes stars of extremely low mass as well as brown dwarfs (substellar objects not massive enough to sustain ...

The Evaporation Valley in the Kepler Planets [PDF]
, 2017 A new piece of evidence supporting the photoevaporation-driven evolution model for low-mass, close-in exoplanets was recently presented by the California–Kepler Survey. The radius distribution of the Kepler planets is shown to be bimodal, with a “valley”

, 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 ...

Occurrence Rates of Planets Orbiting FGK Stars: Combining Kepler DR25, Gaia DR2, and Bayesian Inference [PDF]
Astronomical Journal, 2019 We characterize the occurrence rate of planets, ranging in size from 0.5 to 16 R⊕, orbiting FGK stars with orbital periods from 0.5 to 500 days. Our analysis is based on results from the “DR25” catalog of planet candidates produced by NASA’s Kepler ...
