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 ...

Hot Exoplanetary Atmospheres in 3D
Remote Sensing, 2023 Hot giant exoplanets are very exotic objects with no equivalent in the Solar System that allow us to study the behavior of atmospheres under extreme conditions.

About the Foroughi Cup and about the seven planets in the Ancient World [PDF]
Archaeoastronomy and Ancient Technologies, 2018 The Foroughi Cup is an artefact of the 8th century BC of Aramaic cultural context, inside which images of stars and constellations are reproduced. In this study of ours we start from the conclusions reached by Amadasi Guzzo and Castellani in their two ...

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”

Celebrating 30 years of science from the James Clerk Maxwell Telescope [PDF]
Royal Society Open Science, 2017 The James Clerk Maxwell Telescope (JCMT) has been the world’s most successful single-dish telescope at submillimetre wavelengths since it began operations in 1987. From the pioneering days of single-element photometers and mixers, through to the state-of-

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.

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 ...

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

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 ...
