The Kepler-454 System: A Small, Not-rocky Inner Planet, a Jovian World, and a Distant Companion

Sara Gettel, David Charbonneau, Courtney D. Dressing +47

Kepler-454 (KOI-273) is a relatively bright (V = 11.69 mag), Sun-like starthat hosts a transiting planet candidate in a 10.6 d orbit. From spectroscopy, we estimate the stellar tem…

Oscillation frequencies for 35 \Kepler solar-type planet-hosting stars using Bayesian techniques and machine learning

G. R. Davies, V. Silva Aguirre, T. R. Bedding +16

\Kepler has revolutionised our understanding of both exoplanets and their host stars. Asteroseismology is a valuable tool in the characterisation of stars and \Kepler is an excelle…

Asteroseismology of solar-type stars with K2

W. J. Chaplin, M. N. Lund, R. Handberg +44

We present the first detections by the NASA K2 Mission of oscillations in solar-type stars, using short-cadence data collected during K2 Campaign\,1 (C1). We understand the asteros…

Ages and fundamental properties of Kepler exoplanet host stars from asteroseismology

V. Silva Aguirre, G. R. Davies, S. Basu +21

We present a study of 33 {\it Kepler} planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individua…

KOI-3158: The oldest known system of terrestrial-size planets

T. L. Campante, T. Barclay, J. J. Swift +38

The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. Whil…

An ancient extrasolar system with five sub-Earth-size planets

T. L. Campante, T. Barclay, J. J. Swift +38

The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
