The Clear Sky Corridor: Insights Towards Aerosol Formation in Exoplanets Using An AI-based Survey of Exoplanet Atmospheres [PDF]
The Astronomical JournalAbstract Producing optimized and accurate transmission spectra of exoplanets from telescope data has traditionally been a manual and labor intensive procedure. Here we present the results of the first attempt to improve and standardize this procedure by using artificial-intelligence-based (AI-based) processing of light curves and ...

The eccentricity-mass distribution of exoplanets: signatures of different formation mechanisms? [PDF]
Astronomy & Astrophysics, 2007 We examine the distributions of eccentricity and host star metallicity of exoplanets as a function of their mass. Planets with M sin i >~ 4 M_J have an eccentricity distribution consistent with that of binary stars, while planets with M sin ...

Characterisation of exoplanet host stars: A window into planet formation [PDF]
Proceedings of the International Astronomical Union, 2017 AbstractThe detection of thousands of planets orbiting stars other than the Sun has shown that planets are common throughout the Galaxy. However, the diversity of systems found has also raised many questions regarding the process of planet formation and evolution. Interestingly, but perhaps not unexpectedly, crucial information to constraint the planet

Methane throughout the atmosphere of the warm exoplanet WASP-80b [PDF]
Nature, 2023 Transmission and emission spectra of the 825 K warm Jupiter WASP-80b taken with the NIRCam instrument of the JWST show strong evidence of CH_4 at greater than 6σ significance The abundances of main carbon- and oxygen-bearing gases in the atmospheres of ...

Self-consistent atmosphere modeling with cloud formation for low-mass stars and exoplanets [PDF]
Astronomy & Astrophysics, 2017 Context: Low-mass stars and extrasolar planets have ultra-cool atmospheres where a rich chemistry occurs and clouds form. The increasing amount of spectroscopic observations for extrasolar planets requires self-consistent model atmosphere simulations to consistently include the formation processes that determine cloud formation and their feedback onto ...

Vanadium oxide and a sharp onset of cold-trapping on a giant exoplanet [PDF]
Nature, 2023 The abundance of refractory elements in giant planets can provide key insights into their formation histories^ 1 . Owing to the low temperatures of the Solar System giants, refractory elements condense below the cloud deck, limiting sensing capabilities ...

Collisional formation of massive exomoons of superterrestrial exoplanets [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Exomoons orbiting terrestrial or superterrestrial exoplanets have not yet been discovered; their possible existence and properties are therefore still an unresolved question. Here, we explore the collisional formation of exomoons through giant planetary impacts. We make use of smooth particle hydrodynamical collision simulations

A Neptune-mass exoplanet in close orbit around a very low-mass star challenges formation models
Science, 2023 Theories of planet formation predict that low-mass stars should rarely host exoplanets with masses exceeding that of Neptune. We used radial velocity observations to detect a Neptune-mass exoplanet orbiting LHS 3154, a star that is nine times less ...
