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

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.ABSTRACT In our search for life beyond the Solar System, certain planetary bodies may be more conducive to life than Earth. However, the observability of these “superhabitable” (SH) planets in the habitable zones around K dwarf stars has not been fully modeled. This study addresses this gap by modeling the atmospheres of SH exoplanets.

Initial Thermal States of Super‐Earth Exoplanets and Implications for Early Dynamos
Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.Abstract The accretion of Earth and the formation of a metallic core released a large amount of primordial heat and may have enabled its evolution into a habitable world. Metal‐silicate segregation likely occurs in super‐Earth exoplanets as well, but its influence on their initial thermal states has not been fully examined.

Toward an initial mass function for giant planets
, 2017 The distribution of exoplanet masses is not primordial. After the initial stage of planet formation is complete, the gravitational interactions between planets can lead to the physical collision of two planets, or the ejection of one or more planets from

MARVEL Analysis of High‐Resolution Rovibrational Spectra of 16O13C18O
Journal of Computational Chemistry, Volume 46, Issue 1, January 5, 2025.12348 measured transitions in the wavenumber range 578–9318 cm−1 for carbon dioxide (isotopologue 638) were used° to calculating 3975 empirical rovibrational energy levels with J° up to 82. ABSTRACT A large set of validated experimental transitions and empirical rovibrational energy levels are reported for the fifth most abundant carbon dioxide ...
