Space Weather, 2022 The present study aims at characterizing the habitability conditions of exoplanets with an Earth‐like magnetosphere inside the habitable zone of M and F stars, caused by the direct deposition of the stellar wind on the exoplanet surface.

Classifying Exoplanets with a Gaussian Mixture Model
The Open Journal of Astrophysics, 2018 Recently, Odrzywolek and Rafelski have found three distinct categories of exoplanets, when they are classified based on density. We first carry out a similar classification of exoplanets according to their density using the Gaussian Mixture Model ...

Interiors of Terrestrial Planets in Metric-Affine Gravity
Universe, 2021 Using a semiempirical approach, we show that modified gravity affects the internal properties of terrestrial planets, such as their physical characteristics of a core, mantle, and core–mantle boundary.

Magnetic Scaling Laws for the Atmospheres of Hot Giant Exoplanets
, 2011 We present scaling laws for advection, radiation, magnetic drag and ohmic dissipation in the atmospheres of hot giant exoplanets. In the limit of weak thermal ionization, ohmic dissipation increases with the planetary equilibrium temperature (T_eq ...

Adaptive Optics Observations of Exoplanets, Brown Dwarfs, & Binary Stars [PDF]
, 2011 The current direct observations of brown dwarfs and exoplanets have been obtained using instruments not specifically designed for overcoming the large contrast ratio between the host star and any wide-separation faint companions. However, we are about to

Observations of circumstellar disks in scattered light with SPHERE at the VLT
Comptes Rendus. Physique, 2023 The technological developments initiated in the early 21$^{\rm st}$ century have led to the implementation of “planet finders” instruments on 8-m class telescopes which are in operation since 2014-2015. Such facilities are at the inception of significant

The Observational Case for Jupiter Being a Typical Massive Planet
, 2002 We identify a subsample of the recently detected extrasolar planets that is minimally affected by the selection effects of the Doppler detection method.

The contribution of the major planet search surveys to EChO target selection [PDF]
, 2014 The EChO core science will be based on a three tier survey, each with increasing sensitivity, in order to study the population of exo-planets from super-Earths to Jupiter-like planets, in the very hot to temperate zones (temperatures of 300 K - 3000 K ...
