Scientists searching for habitable planets beyond Earth shouldn't overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at Arlington physicists.

We make a preliminary assessment on the habitability of potential rocky exoplanets around Alpha Centauri B.

Superhabitable Worlds

To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable.

A general formulation to compute habitable zones for binary stars is presented.

Possible Climates on Terrestrial Exoplanets

What kind of environment may exist on terrestrial planets around other stars? In spite of the lack of direct observations, it may not be premature to speculate on exoplanetary climates, for instance to optimize future telescopic observations, or to assess the probability of habitable worlds.

On the Radius of Habitable Planets

The conditions that a planet must fulfill to be habitable are not precisely known. However, it is comparatively easier to define conditions under which a planet is very likely not habitable.

We used Keck adaptive optics observations to identify the first planet discovered by microlensing to lie in or near the habitable zone.

With most planets and planetary candidates detected in the stellar habitable zone being super-Earths and gas giants, rather than Earth-like planets, we naturally wonder if their moons could be habitable.

In today's mailing, Hogg et al. propose image modeling techniques to maintain 10-ppm-level precision photometry in Kepler data with only two working reaction wheels.

The characterization of the atmospheres of habitable-zone Earth-mass exoplanets that transit across main-sequence stars, let alone the detection of bio-markers in their atmospheres, will be challenging even with future facilities. It has been noted that white dwarfs (WDs) have long-lived habitable zones and that a large fraction of WDs may host planets.

We use the sample of known stars and brown dwarfs within 5 pc of the Sun, supplemented with AFGK stars within 10 pc, to determine which stellar spectral types provide the most habitable real estate - defined to be locations where liquid water could be present on Earth-like planets.

New Earth-like Planets Found

A team of scientists, including Carnegie's Alan Boss, has discovered two Earth-like planets in the habitable orbit of a Sun-like star. Their work is published in Science Express.

Hitherto, six P-type planets are found around five binary systems, i.e. Kepler-16 b, 34 b, 35 b, 38 b, 47 b, c, which are all Neptune or Jupiter-like planets. The stability of planets and the habitable zones are influenced by the gravitational and radiative perturbations of binary companions.
