That's How We Roll: The NASA K2 Mission Science Products and Their Performance Metrics

Jeffrey E. Van Cleve, Steve B. Howell, Jeffrey C. Smith +6

NASA's exoplanet Discovery mission Kepler was reconstituted as the K2 mission a year after the failure of the 2nd of Kepler's 4 reaction wheels in May 2013. The new spacecraft poin…

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…

EPIC 201585823, a rare triple-mode RR Lyrae star discovered in K2 mission data

Donald W. Kurtz, Dominic M. Bowman, Simon J. Ebo +3

We have discovered a new, rare triple-mode RR Lyr star, EPIC 201585823, in the Kepler K2 mission Campaign 1 data. This star pulsates primarily in the fundamental and first-overtone…

Oscillating red giants observed during Campaign 1 of the Kepler K2 mission: New prospects for galactic archaeology

D. Stello, D. Huber, S. Sharma +21

NASA's re-purposed Kepler mission -- dubbed K2 -- has brought new scientific opportunities that were not anticipated for the original Kepler mission. One science goal that makes op…

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…

K2P A photometry pipeline for the K2 mission

Mikkel N. Lund, Rasmus Handberg, Guy R. Davies +2

With the loss of a second reaction wheel, resulting in the inability to point continuously and stably at the same field of view, the NASA Kepler satellite recently entered a new mo…

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…
