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.

The WASP-South search for transiting exoplanets
EPJ Web of Conferences, 2011 Since 2006 WASP-South has been scanning the Southern sky for transiting exoplanets. Combined with Geneva Observatory radial velocities we have so far found over 30 transiting exoplanets around relatively bright stars of magnitude 9–13.

The Habitability of the Galactic Bulge
Life, 2020 We present a new investigation of the habitability of the Milky Way bulge, that expands previous studies on the Galactic Habitable Zone. We discuss existing knowledge on the abundance of planets in the bulge, metallicity and the possible frequency of ...

Chemical modeling of exoplanet atmospheres [PDF]
, 2014 The past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored. Thanks to current observational technologies, we are able to determine some information about the atmospheric composition,

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Significant volcanic activity continued for billions of years since 3.5–4 Gyr ago in the Procellarum KREEP Terrane (PKT) of the Moon, but not so significant outside the PKT. To understand this volcanic history, we developed a 2‐D numerical model of magmatism and mantle convection; the effects of the PKT on lunar evolution are considered by ...

The Astrobiology of Alien Worlds: Known and Unknown Forms of Life
Universe, 2020 Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the environment for internal maintenance and activity, and capable of

Radiative transfer and inversion codes for characterizing planetary atmospheres: an overview
Frontiers in Astronomy and Space Sciences, 2023 The study of planetary atmospheres is crucial for understanding the origin, evolution, and processes that shape celestial bodies like planets, moons and comets.

Detection of Exoplanet as a Binary Source of Microlensing Events in WFIRST Survey [PDF]
, 2019 We investigate the possibility of exoplanet detection orbiting source stars in microlensing events through WFIRST observations. We perform a Monto Carlo simulation on the detection rate of exoplanets via microlensing, assuming that each source star has at least one exoplanet.
