Extracting surface rotation periods of solar-like Kepler targets
T. Ceillier, R. A. Garcia, D. Salabert +1
We use various method to extract surface rotation periods of Kepler targets exhibiting solar-like oscillations and compare their results.
Surface rotation of solar-like oscillating stars
T. Ceillier, R. A. Garcia, D. Salabert +1
In this work, we use different methods to extract the surface rotation rate of Kepler targets showing solar-like oscillations.
Gap interpolation by inpainting methods : Application to Ground and Space-based Asteroseismic data
Sandrine Pires, Savita Mathur, Rafael A. Garcia +3
In asteroseismology, the observed time series often suffers from incomplete time coverage due to gaps. The presence of periodic gaps may generate spurious peaks in the power spectr…
The APOKASC Catalog: An Asteroseismic and Spectroscopic Joint Survey of Targets in the Kepler Fields
Marc H. Pinsonneault, Yvonne Elsworth, Courtney Epstein +42
We present the first APOKASC catalog of spectroscopic and asteroseismic properties of 1916 red giants observed in the Kepler fields. The spectroscopic parameters provided from the…
Bayesian distances and extinctions for giants observed by Kepler and APOGEE
Thaíse S. Rodrigues, Léo Girardi, Andrea Miglio +30
We present a first determination of distances and extinctions for individual stars in the first release of the APOKASC catalogue, built from the joint efforts of the Apache Point O…
Rotation periods and ages of solar analogs and solar twins revealed by the Kepler Mission
J. -D. do Nascimento, R. A. Garcia, S. Mathur +7
A new sample of solar analogs and twin candidates have been constructed and studied, with particular attention to their light curves from NASA's Kepler mission. This letter aims to…
Non-radial oscillations in M-giant semi-regular variables: Stellar models and Kepler observations
D. Stello, D. Compton, T. R. Bedding +6
The success of asteroseismology relies heavily on our ability to identify the frequency patterns of stellar oscillation modes. For stars like the Sun this is relatively easy becaus…
Impact on asteroseismic analyses of regular gaps in Kepler data
R. A. Garcıa, S. Mathur, S. Pires +11
The NASA Kepler mission has observed more than 190,000 stars in the constellations of Cygnus and Lyra. Around 4 years of almost continuous ultra high-precision photometry have been…
Photometric magnetic-activity metrics tested with the Sun: Application to Kepler M dwarfs
S. Mathur, D. Salabert, R. A. Garcia +1
The Kepler mission has been providing high-quality photometric data leading to many breakthroughs in the exoplanet search and in stellar physics. Stellar magnetic activity results…
Testing the Asteroseismic Mass Scale Using Metal-Poor Stars Characterized with APOGEE and Kepler
Courtney R. Epstein, Yvonne P. Elsworth, Jennifer A. Johnson +29
Fundamental stellar properties, such as mass, radius, and age, can be inferred using asteroseismology. Cool stars with convective envelopes have turbulent motions that can stochast…
Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
R. A. Garcia, T. Ceillier, D. Salabert +16
Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied for thousands of stars…
Properties of 42 Solar-type Kepler Targets from the Asteroseismic Modeling Portal
T. S. Metcalfe, O. L. Creevey, G. Dogan +39
Recently the number of main-sequence and subgiant stars exhibiting solar-like oscillations that are resolved into individual mode frequencies has increased dramatically. While only…
