Abstract Proper characterization of the host star to a planet is a key element to the understanding of its overall properties. The star has a direct impact through the modification of the structure and evolution of the planet atmosphere by being the overwhelmingly larger source of energy. The star plays a central role in shaping the structure, evolution, and even determining the mere existence of planetary atmospheres. The vast majority of the stellar flux is well understood thanks to the… 
The Mars Atmosphere and Volatile Evolution (MAVEN) Mission
The MAVEN spacecraft launched in November 2013, arrived at Mars in September 2014, and completed commissioning and began its one-Earth-year primary science mission in November 2014. The orbiter’s
A Closer Earth and the Faint Young Sun Paradox: Modification of the Laws of Gravitation or Sun/Earth Mass Losses?
Given a solar luminosity LAr = 0.75L0 at the beginning of the Archean 3.8 Ga ago, where L0 is the present-day one, if the heliocentric distance, r, of the Earth was rAr = 0.956r0, the solar
The evolution of habitable climates under the brightening Sun
On water‐dominated planets, warming from increased solar insolation is strongly amplified by the water vapor greenhouse feedback. As the Sun brightens due to stellar evolution, Earth will become
Carbon Cycling and Habitability of Massive Earth-like Exoplanets
As the number of detected rocky extrasolar planets increases, the question of whether their surfaces could be habitable is becoming more pertinent. On Earth, the long-term carbonate-silicate cycle is

The supercharged nature of the Earth’s geothermal core can be demonstrated by three thought experiments exhibiting it is tremendously more powerful than any other terrestrial object in the solar
Stellar Aspects of Habitability – Characterizing Target Stars for Terrestrial Planet Search Missions
In this paper we present and discuss the criteria for selecting potential target stars suitable for the search for Earth like planets, with a special emphasis on the stellar aspects of habitability.
Stellar aspects of habitability--characterizing target stars for terrestrial planet-finding missions.
Using the Darwin All Sky Star Catalogue (DASSC), the selection criteria, configuration-dependent subcatalogues, and the implication of stellar activity for habitability are discussed.

Whether an exoplanet retains its atmosphere and surface water depends on many factors. I will first describe the two main mass-loss mechanisms for exoplanet atmospheres. The main thermal process is
Solar Models with Dynamic Screening and Early Mass Loss Tested by Helioseismic, Astrophysical, and Planetary Constraints
The faint young Sun paradox remains an open question. Presented here is one possible solution to this apparent inconsistency, a more massive early Sun. Based on the conditions on early Earth and


The evolution of solar ultraviolet luminosity
In view of the major role of the sun in defining the properties of planetary atmospheres, their evolution cannot be fully understood outside the context of an evolving sun. The ultraviolet radiation
The effect of tidal locking on the magnetospheric and atmospheric evolution of ``Hot Jupiters''
We study the interaction between the planetary magnetosphere and atmosphere of the close-in extrasolar planets HD 209458b and OGLE-TR-56b with the stellar wind during the evolution of their host
Planetary Magnetic Fields and Solar Forcing: Implications for Atmospheric Evolution
Abstract The solar wind and the solar XUV/EUV radiation constitute a permanent forcing of the upper atmosphere of the planets in our solar system, thereby affecting the habitability and chances for
A Comparative Study of the Influence of the Active Young Sun on the Early Atmospheres of Earth, Venus, and Mars
Abstract Because the solar radiation and particle environment plays a major role in all atmospheric processes such as ionization, dissociation, heating of the upper atmospheres, and thermal and
Evolution of the Solar Activity over Time and Effects on Planetary Atmospheres. I. High-Energy Irradiances (1-1700 Å)
We report on the results of the Sun in Time multiwavelength program (X-rays to UV) of solar analogs with ages covering ~0.1-7 Gyr. The chief science goals are to study the solar magnetic dynamo and
The X-Ray Sun in Time: A Study of the Long-Term Evolution of Coronae of Solar-Type Stars
We have used the ASCA and ROSAT X-ray satellites to probe the coronae of a sample of nine solar-like G stars. These stars are all ostensibly single with ages ranging from 70 Myr to 9 Gyr and have
Energetic neutral atoms as the explanation for the high-velocity hydrogen around HD 209458b
It is shown that the measured transit-associated Lyα absorption can be explained by the interaction between the exosphere of HD 209458b and the stellar wind, and that radiation pressure alone cannot explain the observations.
Evolution of the solar ionizing flux
A young magnetically active Sun, with enhanced ionizing radiations and an elevated solar wind, might have contributed to erosion of the primordial atmosphere of Mars (which is particularly vulnerable
Mass loss mechanisms in evolved stars
SummaryMass loss is a very important phenomenon for stellar evolution. In the late stages of stars it becomes fairly high (up to 10−4 M⊙/yr) though with a much decreased expansion velocity (about 30
Outer atmospheres of cool stars. IX - A survey of ultraviolet emission from F-K dwarfs and giants with IUE
Low-dispersion ultraviolet spectra (1150-2000 A) of a representative sample of cool stars, including dwarfs and giants of spectral types F-K, obtained with the IUE, are examined. The observation and
