Kepler-69c, also known as KOI 172.02, is a planet candidate discovered by the Kepler space telescope. It is a "super-Earth" that could hold water on its surface.

"As NASA's first exoplanets mission, Kepler has made a dramatic entrance on the planet-hunting scene," said Jon Morse, director of the Science Mission Directorate's Astrophysics Division at NASA Headquarters in Washington. "Detecting this planet's atmosphere in just the first 10 days of data i...
For the false positive KOI 4.01, we found that the eclipses could be modelled by a faint background classical Algol as effectively as by a transiting exoplanet. Our empirical checks of limb-darkening, in the cases of KOI 1.01 and 12.01, revealed that the assigned stellar temperatures are ...
We present a new framework to characterize the occurrence rates of planet candidates identified by Kepler based on hierarchical Bayesian modeling, Approximate Bayesian Computing (ABC), and sequential importance sampling. For this study we adopt a simple 2-D grid in planet radius and orbital period ...
Extrasolar planets that pass in front of their host star (transit) cause a temporary decrease in the apparent brightness of the star, providing a direct measure of the planet's size and orbital period. In some systems with multiple transiting planets, the times of the transits are measurably ...

Kepler-1649c围绕一颗红矮星运行，如果这颗星发生爆发，可能会对其周围的任何生命构成潜在威胁。此外，这颗行星的大气层仍然是个未知数，而且对其尺寸的计算也可能存在偏差。关于这项研究的详细信息已发表在最新一期的《天体物理学杂志快报》上，文章标题为《A Habitable-zone Earth-sized Planet Rescued from...
Three systems have planet candidates that are near mean motion commensurabilities---two near 2:1 and one just outside 5:2. We discuss the implications that multitransiting systems have on the distribution of orbital inclinations in planetary systems, and hence their dynamical histories; as well ...
