Sentences with phrase «giant planet candidates»

Not exact matches

Revising the properties of the associated planet candidates based on the updated host star characteristics and refitting the transit photometry, we find that our sample contains 20 planets or planet candidates with radii smaller than 1.25 Earth radii, 20 super-Earths (1.25 - 2 Earth radii), 20 small Neptunes (2 - 4 Earth radii), three large Neptunes (4 - 6 Earth radii), and eight giant planets (> 6 Earth radii).

A comparison with stellar properties in the planet - candidate catalog by Batalha et al. shows that radii for subgiants and giants obtained from spectroscopic follow - up are systematically too low by up to a factor of 1.5, while the properties for unevolved stars are in good agreement.

Using the revised stellar properties, we recalculate the radii for 107 planet candidates in our sample, and comment on candidates for which the radii change from a previously giant - planet / brown - dwarf / stellar regime to a sub-Jupiter size, or vice versa.

What remains to be found among the Giant Planets like Jupiter and Saturn are some candidates that combine all three ingredients for primitive life: energy, liquid water and some atmosphere.
