Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary mass companion [PDF]
Astronomy & Astrophysics, 2022 Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner companion in the system.

Exoplanet Characterization using Conditional Invertible Neural Networks [PDF]
Astronomy & Astrophysics, 2022 The characterization of an exoplanet's interior is an inverse problem, which requires statistical methods such as Bayesian inference in order to be solved. Current methods employ Markov Chain Monte Carlo (MCMC) sampling to infer the posterior probability

A simple analysis of earthlike exoplanets [PDF]
arXiv, 2021 The astrobiology is an interdisciplinary science, combining the methods and the means of physics, biology, chemistry and astronomy. Its main purpose is to find out if the exoplanets are habitable and if so, to confirm life on them. The basic conditions for habitability are the essential ones, like these on the Earth.

Aerosol Composition of Hot Giant Exoplanets Dominated by Silicates and Hydrocarbon Hazes [PDF]
, 2020 Aerosols are common in the atmospheres of exoplanets across a wide swath of temperatures, masses, and ages. These aerosols strongly impact observations of transmitted, reflected, and emitted light from exoplanets, obfuscating our understanding of exoplanet thermal structure and composition.
