Analytic Light Curves for Planetary Transit Searches
We present exact analytic formulae for the eclipse of a star described by quadratic or nonlinear limb darkening. In the limit that the planet radius is less than a tenth of the stellar radius, we
Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1
TLDR
The observations reveal that at least seven planets with sizes and masses similar to those of Earth revolve around TRAPPIST-1, and the six inner planets form a near-resonant chain, such that their orbital periods are near-ratios of small integers.
SDSS-III: MASSIVE SPECTROSCOPIC SURVEYS OF THE DISTANT UNIVERSE, THE MILKY WAY, AND EXTRA-SOLAR PLANETARY SYSTEMS
Building on the legacy of the Sloan Digital Sky Survey (SDSS-I and II), SDSS-III is a program of four spectroscopic surveys on three scientific themes: dark energy and cosmological parameters, the
A map of the day–night contrast of the extrasolar planet HD 189733b
TLDR
Observations of HD 189733, the closest of these eclipsing planetary systems, over half an orbital period are reported, from which a ‘map’ of the distribution of temperatures is constructed, indicating that energy from the irradiated dayside is efficiently redistributed throughout the atmosphere.
EXOFAST: A Fast Exoplanetary Fitting Suite in IDL
We present EXOFAST, a fast, robust suite of routines written in IDL that is designed to fit exoplanetary transits and radial velocity variations simultaneously or separately and characterize the
ARCHITECTURE OFKEPLER'S MULTI-TRANSITING SYSTEMS. II. NEW INVESTIGATIONS WITH TWICE AS MANY CANDIDATES
We report on the orbital architectures of Kepler systems having multiple-planet candidates identified in the analysis of data from the first six quarters of Kepler data and reported by Batalha et al.
Masses, Radii, and Orbits of Small Kepler Planets: The Transition From Gaseous to Rocky Planets
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by precise
The Statistics of Albedo and Heat Recirculation on Hot Exoplanets
If both the day-side and night-side effective temperatures of a planet can be measured, it is possible to estimate its Bond albedo, 0 0.8 ?m?to estimate day-side effective temperatures, T d, and
Kepler-36: A Pair of Planets with Neighboring Orbits and Dissimilar Densities
TLDR
Another violation of the orbit-composition pattern is reported: two planets orbiting the same star with orbital distances differing by only 10% and densities differing by a factor of 8, likely a rocky “super-Earth,” whereas the other is more akin to Neptune.
A seven-planet resonant chain in TRAPPIST-1
The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star. At least seven planets similar to Earth in radius and in mass were previously found to transit
