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 …

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–…

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 …
