Planetary habitability: lessons learned from terrestrial analogues [PDF]
International Journal of Astrobiology, 2014 Terrestrial analogue studies underpin almost all planetary missions and their use is essential in the exploration of our Solar system and in assessing the habitability of other worlds.

Tidal Constraints on Planetary Habitability
, 2009 We review how tides may impact the habitability of terrestrial-like planets. If such planets form around low-mass stars, then planets in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces. We discuss 1) decay of semi-major axis, 2) circularization of eccentric orbits, 3) evolution toward zero ...

The occurrence of Jovian planets and the habitability of planetary systems [PDF]
Proceedings of the National Academy of Sciences, 2001 Planets of mass comparable to or larger than Jupiter's have been detected around over 50 stars, and for one such object a definitive test of its nature as a gas giant has been accomplished with data from an observed planetary transit. By virtue of their strong gravitational pull, giant planets define the dynamical and collisional environment within ...

Streaks on martian slopes are dry [PDF]
Nature CommunicationsSlope streaks are dark albedo features on martian slopes that form spontaneously and fade over years to decades. Along with seasonally recurring slope lineae, streak formation has been attributed to aqueous processes, implying the presence of transient ...

Eccentricity Distribution beyond the Snow Line and Implications for Planetary Habitability [PDF]
The Astrophysical Journal LettersA fundamental question in the study of planetary system demographics is: how common is the solar system architecture? The primary importance of this question lies in the potential of planetary systems to create habitable environments, and dissecting the ...

Anomalous transient enhancement of planetary ion escape at Mars [PDF]
Nature CommunicationsAtmospheric ion escape plays a crucial role in the evolution of planetary climate and habitability. While Mars has been the focus of extensive in-situ spacecraft observations, our understanding of ion escape at Mars has been constrained by single-point ...

Dynamical Habitability of Known Extrasolar Planetary Systems [PDF]
The Astrophysical Journal, 2003 Habitability is usually defined as the requirement for a terrestrial planet's atmosphere to sustain liquid water. This definition can be complemented by the dynamical requirement that other planets in the system do not gravitationally perturb terrestrial planets outside of their habitable zone, the orbital region allowing the existence of liquid water.
