Proceedings of the National Academy of Sciences, 2013 Significance Planets around other stars, or exoplanets, are now known to be common in our galaxy. Exoplanets span a much wider range of physical conditions than the planets in our solar system, and include extremely puffy gas giants to compact rocky planets that can have densities as high as that of iron.

Constraining Young Hot Jupiter Occurrence Rate in Stellar Associations Using 2-min Cadence TESS Data
Universe, 2023 The characterization of young planet distribution is essential for our understanding of the early evolution of exoplanets. Here we conduct a systematic search for young planets from young open clusters and associations using the 2-min cadence TESS survey

Optical properties of organic haze analogues in water-rich exoplanet atmospheres observable with JWST [PDF]
Nature Astronomy, 2023 The James Webb Space Telescope (JWST) has begun its scientific mission, which includes the atmospheric characterization of transiting exoplanets. Some of the first exoplanets to be observed by JWST have equilibrium temperatures below 1,000 K, which is a ...

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]
Journal of Astronomy and Space Sciences, 2016 A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet

Orbital Period Refinement of CoRoT Planets with TESS Observations
Frontiers in Astronomy and Space Sciences, 2021 CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first terrestrial exoplanet with a measured size. The precision of the published

A JWST transmission spectrum of the nearby Earth-sized exoplanet LHS 475 b
Nature Astronomy, 2023 The warm Earth-sized planet LHS 475 b is validated and characterized with two transits observed by the JWST. The absence of evident spectroscopic features excludes a substantial hydrogen envelope and indicates that LHS 475 b has either little or no ...

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Exoplanets—planets orbiting around stars other than our own Sun—appear to be common. Significant research effort is now focused on the observation and characterization of exoplanet atmospheres. Species such as water vapour, methane, carbon monoxide and carbon dioxide have been observed in a handful of hot, giant, gaseous planets, but ...
