In subject area: Physics and Astronomy A 'Habitable Zone' refers to the region around a star where a rocky planet could have the right temperature for liquid water to exist on its surface, making it a potential environment for life to thrive. ...
EARTH (Planet)QUINTANA, ElisaThe article reports that a team of astronomers led by Elisa Quintana of the SETI Institute in Mountain View, California discovered a planet that is a similar size to earth orbiting a cool, dim star at just the right distance for liquid water to exist....
Biomarkers, habitability, habitable zone, M stars, resonance, tidal lockingDefinition Tidal locking is a state of dynamical equilibrium between a planet’s spin and orbital angular momentum. Tidally-locked planets on circular orbits may become synchronous rotators, presenting the same solid-body hemisph...
The habitable zone concept was first applied to the space around a star, now called the Circumstellar Habitable Zone. Recently, other, vastly broader, habitable zones have been proposed. We review the historical development of the concept of habitable zones and the present state of the research....
this candidate planet might be capable of supporting liquid water on its surface according to the current definition of the liquid water habitable zone around a star and is not likely to suffer from tidal locking. Also, at an angular separation of ~46 mas, HD 40307 g would be a primary ta...
Definition of a Habitable Zone NASA’s Kepler team had released a diagram in May 2016 showingall the small, habitable-zone planets discovered by the spacecraft thus far. The diagram places exoplanets based on the energy they receive from their host star (x-axis) and how hot that star is ...
Low-mass stars show evidence of vigorous magnetic activity in the form of large flares and coronal mass ejections. Such space weather events may have important ramifications for the habitability and observational fingerprints of exoplanetary atmospheres.
The evolution in understanding of the extent to which tidal interactions between a star and a close orbiting planet can affect a planet’s global energy budget has given rise to an expanded definition of the habitable zone beyond its traditional derivation. Recent studies have found that terrestrial...
Here, we report the detection of a spectroscopic signature of water in the atmosphere of K2-18 b—a planet of eight Earth masses in the habitable zone of an M dwarf7—with high statistical confidence (Atmospheric Detectability Index5 = 5.0, ~3.6σ (refs. 8,9)). In addition, the ...
