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

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 ...

Exoplanets and Their Characterization in the Environment of Galaxy Formation
Journal of Material Sciences and Engineering TechnologyThe exploration of exoplanets has emerged as a pivotal area of research in astrophysics, particularly in understanding their formation and evolution within the context of galaxy formation. This paper presents a comprehensive review of current methodologies for exoplanet detection and characterization, emphasizing the interplay between galactic dynamics

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

Interpreting the Atmospheric Composition of Exoplanets: Sensitivity to Planet Formation Assumptions [PDF]
The Astrophysical Journal, 2022 Abstract Constraining planet formation based on the atmospheric composition of exoplanets is a fundamental goal of the exoplanet community. Existing studies commonly try to constrain atmospheric abundances, or to analyze what abundance patterns a given description of planet formation predicts.
