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.

Lo stato dell’arte nella ricerca dei pianeti extrasolari di tipo terrestre [PDF]
S&F_scienzaefilosofia.it, 2023 State of the art in the search for extrasolar planets In the last three decades, the study of exoplanets has evolved from a marginal field into a vital area of research with significant implications for other sciences and philosophy. In this article, we

இலக்கியங்களில் கோள்களின் இயல்பு / Nature of Planets in Literature [PDF]
International Journal of Tamil Language and Literary Studies, 2022 The study of space objects and matter outside the earth’s atmosphere is called astronomy. Ancestors of Tamil culture undoubtedly had spectacular knowledge about astronomy. It is evident in Tamil literature.

Direct Imaging of Multiple Planets Orbiting the Star HR 8799 [PDF]
Science, 2008 Direct imaging of exoplanetary systems is a powerful technique that can reveal Jupiter-like planets in wide orbits, can enable detailed characterization of planetary atmospheres, and is a key step toward imaging Earth-like planets. Imaging detections are

PLANET-PLANET SCATTERING IN PLANETESIMAL DISKS [PDF]
The Astrophysical Journal, 2009 We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt.

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 ...

Optimized transit detection algorithm to search for periodic transits of small planets [PDF]
Astronomy & Astrophysics, 2019 We present a new method to detect planetary transits from time-series photometry, the transit least squares (TLS) algorithm. TLS searches for transit-like features while taking the stellar limb darkening and planetary ingress and egress into account.

Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458 [PDF]
, 2003 We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The models re- produce the main trends of observed methane dwarfs in near-IR color-magnitude diagrams.

The Nature and Origins of Sub‐Neptune Size Planets [PDF]
Journal of Geophysical Research - Planets, 2020 Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet surveys over the last quarter century.
