Astrophysical Conditions for Planetary Habitability
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. The classical picture of habitable zones primarily relies on the stellar flux allowing liquid water to exist on the surface of an Earth-like planet with a suitable atmosphere. However,...
متن کاملDynamical habitability of planetary systems.
The problem of the stability of planetary systems, a question that concerns only multiplanetary systems that host at least two planets, is discussed. The problem of mean motion resonances is addressed prior to discussion of the dynamical structure of the more than 350 known planets. The difference with regard to our own Solar System with eight planets on low eccentricity is evident in that 60% ...
متن کاملTidal Limits to Planetary Habitability
The habitable zones 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 zones, which are close-in due to decreased stellar luminosity, may also undergo significant tidal heating. Tidal heating may span a wide range for t...
متن کاملTides and the evolution of planetary habitability.
Tides raised on a planet by the gravity of its host star can reduce the planet's orbital semi-major axis and eccentricity. This effect is only relevant for planets orbiting very close to their host stars. The habitable zones of low-mass stars are also close in, and tides can alter the orbits of planets in these locations. We calculate the tidal evolution of hypothetical terrestrial planets arou...
متن کاملAn Index Of Habitability
Perhaps the greatest challenge facing the Human Factors profession is the ability to communicate effectively with their customers. One example is the NASA Standard 3000, which is an extensive compilation of human factors information, but an inefficient tool in the design and evaluation processes. These shortcomings are indicated by the need for interpretation of much of the material by human fa...
