Impact of space weather on climate and habitability of terrestrial-type exoplanets [PDF]
International Journal of Astrobiology, 2019 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 new avenue in the characterization of exoplanetary atmospheres and in the ...

The Habitability of the Galactic Bulge [PDF]
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 ...

Climate variations on Earth-like circumbinary planets
Nature Communications, 2017 Large variations in insolation experienced by circumbinary planets raise the question of the habitability of such planets. Here, the authors show that while the changing insolation does not radically affect habitability, it does impact on the planet’s ...

Habitability of Mars: How Welcoming Are the Surface and Subsurface to Life on the Red Planet?
Geosciences, 2019 Mars is a planet of great interest in the search for signatures of past or present life beyond Earth. The years of research, and more advanced instrumentation, have yielded a lot of evidence which may be considered by the scientific community as proof of

Assessing the Habitability of the TRAPPIST-1 System Using a 3D Climate Model [PDF]
, 2017 The TRAPPIST-1 system provides an extraordinary opportunity to study multiple terrestrial extrasolar planets and their atmospheres. Here, we use the National Center for Atmospheric Research Community Atmosphere Model version 4 to study the possible ...

The subsurface habitability of small, icy exomoons [PDF]
Astronomy & Astrophysics, 2020 Context. Assuming our Solar System as typical, exomoons may outnumber exoplanets. If their habitability fraction is similar, they would thus constitute the largest portion of habitable real estate in the Universe.

Constraints on the habitability of extrasolar moons [PDF]
, 2012 Detections of massive extrasolar moons are shown feasible with the Kepler space telescope. Kepler's findings of about 50 exoplanets in the stellar habitable zone naturally make us wonder about the habitability of their hypothetical moons.

SSRN Electronic Journal, 2013 We show that the optimal consumption of an individual over the life cycle can have the hump shape (inverted U-shape) observed empirically if the preferences of the individual exhibit internal habit formation. In the absence of habit formation, an impatient individual would prefer a decreasing consumption path over life.

Habitability on Early Mars and the Search for Biosignatures with the ExoMars Rover
Astrobiology, 2017 The second ExoMars mission will be launched in 2020 to target an ancient location interpreted to have strong potential for past habitability and for preserving physical and chemical biosignatures (as well as abiotic/prebiotic organics).

Transition to a Moist Greenhouse with CO2 and solar forcing
Nature Communications, 2016 Greenhouse-gas forcing has previously been thought to be rather ineffective at destroying the habitability of Earth-like planets. Here, the authors show that CO2is as effective as solar forcing at causing a climate transition to a Moist-Greenhouse regime
