We review the origin and evolution of the atmospheres of Earth, Venus and Mars from the
time when their accreting bodies were released from the protoplanetary disk a few million …

This work reviews factors which are important for the evolution of habitable Earth-like
planets such as the effects of the host star dependent radiation and particle fluxes on the …

We show that terrestrial planets in the habitable zones of M dwarfs older than∼ 1 Gyr could
have been in runaway greenhouses for several hundred million years following their …

The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

Context. A study of the mass loss enhancement for very close “Hot Jupiters” due to the
gravitational field of the host star is presented. Aims. The influence of the proximity to a …

The changing view of planets orbiting low mass stars, M stars, as potentially hospitable
worlds for life and its remote detection was motivated by several factors, including the …

Atmospheric erosion of CO2-rich Earth-size exoplanets due to coronal mass ejection (CME)-
induced ion pick up within close-in habitable zones of active M-type dwarf stars is …

We review the gas-phase chemistry in extraterrestrial space that is driven by reactions with
atomic and molecular ions. Ions are ubiquitous in space and are potentially responsible for …

ABSTRACT GJ 1132b is a nearby Earth-sized exoplanet transiting an M dwarf, and is
among the most highly characterizable small exoplanets currently known. In this paper, we …

The origin and evolution of Venus', Earth's, Mars' and Titan's atmospheres are discussed
from the time when the active young Sun arrived at the Zero-Age-Main-Sequence. We show …
