Planet occurrence within 0.25 AU of solar-type stars from Kepler
We report the distribution of planets as a function of planet radius, orbital period, and stellar
effective temperature for orbital periods less than 50 days around solar-type (GK) stars. …

The California-Kepler survey. III. A gap in the radius distribution of small planets
The size of a planet is an observable property directly connected to the physics of its formation
and evolution. We used precise radius measurements from the California-Kepler Survey …

Prevalence of Earth-size planets orbiting Sun-like stars
EA Petigura, AW Howard… - Proceedings of the …, 2013 - National Acad Sciences
Determining whether Earth-like planets are common or rare looms as a touchstone in the
question of life in the universe. We searched for Earth-size planets that cross in front of their …

Giant planet occurrence in the stellar mass-metallicity plane
Correlations between stellar properties and the occurrence rate of exoplanets can be used
to inform the target selection of future planet-search efforts and provide valuable clues about …

The occurrence and mass distribution of close-in super-Earths, Neptunes, and Jupiters
The questions of how planets form and how common Earth-like planets are can be addressed
by measuring the distribution of exoplanet masses and orbital periods. We report the …

Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
Type Ia supernovae have been used empirically as ‘standard candles’ to demonstrate the
acceleration of the expansion of the Universe 1 , 2 , 3 even though fundamental details, such …

Obliquities of hot Jupiter host stars: Evidence for tidal interactions and primordial misalignments
We provide evidence that the obliquities of stars with close-in giant planets were initially
nearly random, and that the low obliquities that are often observed are a consequence of star–…
