KIC 9832227: Using Vulcan Data to Negate The 2022 Red Nova Merger Prediction
Quentin J Socia, William F Welsh, Donald R Short +5
KIC 9832227 is a contact binary whose 11 hr orbital period is rapidly changing. Based on the apparent exponential decay of its period, the two stars were predicted to merge in earl…
The Kepler Follow-Up Observation Program. II. Stellar Parameters from Medium- and High-Resolution Spectroscopy
E. Furlan, D. R. Ciardi, W. D. Cochran +22
We present results from spectroscopic follow-up observations of stars identified in the Kepler field and carried out by teams of the Kepler Follow-Up Observation Program. Two sampl…
Revised Stellar Properties of Kepler Targets for the Q1-17 (DR25) Transit Detection Run
Savita Mathur, Daniel Huber, Natalie M. Batalha +14
The determination of exoplanet properties and occurrence rates using Kepler data critically depends on our knowledge of the fundamental properties (such as temperature, radius and…
Kepler Eclipsing Binary Stars. VII. The Catalog of Eclipsing Binaries Found in the Entire Kepler Data-Set
Brian Kirk, Kyle Conroy, Andrej Prša +47
The primary Kepler Mission provided nearly continuous monitoring of ~200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary syst…
Kepler-21b: A 1.6REarth Planet Transiting the Bright Oscillating F Subgiant Star HD 179070
Steve B. Howell, Jason F. Rowe, Stephen T. Bryson +63
We present Kepler observations of the bright (V=8.3), oscillating star HD 179070. The observations show transit-like events which reveal that the star is orbited every 2.8 days by…
The Kepler Cluster Study: Stellar Rotation in NGC6811
Søren Meibom, Sydney A. Barnes, David W. Latham +17
We present rotation periods for 71 single dwarf members of the open cluster NGC6811 determined using photometry from NASA's Kepler Mission. The results are the first from The Keple…
Kepler Eclipsing Binary Stars. II. 2165 Eclipsing Binaries in the Second Data Release
Robert W. Slawson, Andrej Prsa, William F. Welsh +21
The Kepler Mission provides nearly continuous monitoring of ~156 000 objects with unprecedented photometric precision. Coincident with the first data release, we presented a catalo…
Predicting the detectability of oscillations in solar-type stars observed by Kepler
W. J. Chaplin, H. Kjeldsen, T. R. Bedding +49
Asteroseismology of solar-type stars has an important part to play in the exoplanet program of the NASA Kepler Mission. Precise and accurate inferences on the stellar properties th…
KOI-54: The Kepler Discovery of Tidally-Excited Pulsations and Brightenings in a Highly Eccentric Binary
William F. Welsh, Jerome A. Orosz, Conny Aerts +27
Kepler observations of the star HD 187091 (KID 8112039, hereafter KOI-54) revealed a remarkable light curve exhibiting sharp periodic brightening events every 41.8 days with a supe…
Photometric Variability in Kepler Target Stars. II. An Overview of Amplitude, Periodicity, and Rotation in First Quarter Data
Gibor Basri, Lucianne M. Walkowicz, Natalie Batalha +10
We provide an overview of stellar variability in the first quarter of data from the Kepler mission. The intent of this paper is to examine the entire sample of over 150,000 target…
White-light flares on cool stars in the Kepler Quarter 1 Data
Lucianne M. Walkowicz, Gibor Basri, Natalie Batalha +11
We present the results of a search for white light flares on the ~23,000 cool dwarfs in the Kepler Quarter 1 long cadence data. We have identified 373 flaring stars, some of which…
Kepler Eclipsing Binary Stars. I. Catalog and Principal Characterization of 1879 Eclipsing Binaries in the First Data Release
Andrej Prsa, Natalie M. Batalha, Robert W. Slawson +12
The Kepler space mission is devoted to finding Earth-size planets in habitable zones orbiting other stars. Its large, 105-deg field-of-view features over 156,000 stars that are obs…
Kepler Observations of Transiting Hot Compact Objects
Jason F. Rowe, William J. Borucki, David Koch +18
Kepler photometry has revealed two unusual transiting companions orbiting an early A-star and a late B-star. In both cases the occultation of the companion is deeper than the trans…
Photometric Variability in Kepler Target Stars: The Sun Among Stars -- A First Look
Gibor Basri, Lucianne M. Walkowicz, Natalie Batalha +10
The Kepler mission provides an exciting opportunity to study the lightcurves of stars with unprecedented precision and continuity of coverage. This is the first look at a large sam…
Selection, Prioritization, and Characteristics of Kepler Target Stars
N. M. Batalha, W. J. Borucki, D. G. Koch +8
The Kepler Mission began its 3.5-year photometric monitoring campaign in May 2009 on a select group of approximately 150,000 stars. The stars were chosen from the ~half million in…
A Transiting Hot Jupiter Orbiting a Metal-Rich Star
Edward W. Dunham, William J. Borucki, David G. Koch +22
We announce the discovery of Kepler-6b, a transiting hot Jupiter orbiting a star with unusually high metallicity, [Fe/H] = +0.34 +/- 0.04. The planet's mass is about 2/3 that of Ju…
