TIDAL LIMITS TO PLANETARY HABITABILITY [PDF]
The Astrophysical Journal, 2009 The habitable zones (HZs) of main-sequence stars have traditionally been defined as the range of orbits that intercept the appropriate amount of stellar flux to permit surface water on a planet. Terrestrial exoplanets discovered to orbit M stars in these

Astrophysical Conditions for Planetary Habitability [PDF]
, 2014 With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal point in exoplanetary research.

Impact of Stellar Superflares on Planetary Habitability [PDF]
Astrophysical Journal, 2019 High-energy radiation caused by exoplanetary space weather events from planet-hosting stars can play a crucial role in conditions promoting or destroying habitability in addition to the conventional factors.

Evryscope and K2 Constraints on TRAPPIST-1 Superflare Occurrence and Planetary Habitability [PDF]
Astrophysical Journal, 2020 The nearby ultracool dwarf TRAPPIST-1 possesses several Earth-sized terrestrial planets, three of which have equilibrium temperatures that may support liquid surface water, making it a compelling target for exoplanet characterization.

Eccentricity Distribution beyond the Snow Line and Implications for Planetary Habitability [PDF]
A 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 ...

The Design of a Bioinspired Integrated Total Habitability Instrument for Planetary Exploration: A Review of Potential Sensing Technologies [PDF]
BiomimeticsOne key objective of astrobiology is to investigate and discover if other planetary bodies are habitable. The determination of whether an environment is habitable to known life requires measuring liquid water, CHNOPS elements, other nutrients, and energy

Stellar flares versus luminosity: XUV-induced atmospheric escape and planetary habitability [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (1030–1038 erg), a fraction of which lies in X-rays and extreme ultraviolet (XUV).

Planetary Magnetic Fields and Habitability in Super Earths
Open Astronomy, 2018 This work seeks to summarize some special aspects of a type of exoplanets known as super-Earths (SE), and the direct influence of these aspects in their habitability.

Long-Term Planetary Habitability and the Carbonate-Silicate Cycle [PDF]
Astrobiology, 2018 The potential habitability of an exoplanet is traditionally assessed by determining whether its orbit falls within the circumstellar “habitable zone” of its star, defined as the distance at which water could be liquid on the surface of a planet ...
