In November a team led by Washington State University astrobiologist Dirk Schulze - Makuch devised the Planetary Habitability Index, or PHI, a scoring system for distant worlds that measures their suitability for any kind of life, not merely life as we know it.

The implications for habitability in these systems were the focus of the Division of Planetary Sciences meeting.

Star A's late spectral type and dim luminosity puts it possibly close to the lower limit of habitability for (multicellular) Earth - type plant and animal life, given the redness of its light and the increased risk of tidal locking from the closeness of the orbit necessary for liquid water on a planetary surface.

This has strong implications for astrobiology and planetary habitability as any putative life forms near the surface would be exposed to large radiation doses capable of sterilizing the top ~ 20 cm of the Martian subsurface (Simonsen & Nealy 1993; Mileikowsky et al. 2000; Pavlov et al. 2002; Dartnell 2011; Dartnell et al. 2007a, 2007b, 2010).

Planets that are regularly swapped between their stars may be unlikely candidates for habitability, but the more compact a planetary system, the less likely a planet will be stolen by a passing star.

In addition, planetary habitability - related proposals accounted for a very large fraction of the major proposals that responded to the latest opportunity to join the NASA Astrobiology Institute.

Secondly: «The Planetary Habitability Index is based -LRB-...) appropriate chemistry, and the potential for holding a liquid solvent,» as the paper's abstract notes.

The Planetary Habitability Index is based on «the presence of a stable substrate, available energy, appropriate chemistry, and the potential for holding a liquid solvent,» as the paper's abstract notes.

The prospects for the habitability of M - dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low - mass stars, as compared to hotter, more luminous Sun - like stars.

The other factor that arises from this is that CMEs, of all the various dangerous stellar eminations, appear to be most responsible for planetary atmospheric erosion so anything that mitigates their effect has got to be good in terms of planetary habitability and most of all in M dwarf systems where the «habitable zone» is close to the star and well within the region of synchronous rotation.

The Planetary Habitability Laboratory (U Puerto Rico, Arecibo) notes that both Tau Ceti e and f fall within the Extended Habitability Zone where larger planets with thicker atmospheres might retain sufficient heat for water to be liquid.
