The influence of metallicity on stellar differential rotation and magnetic activity
Christoffer Karoff, Travis S. Metcalfe, Angela R. G. Santos +20
Observations of Sun-like stars over the last half-century have improved our understanding of how magnetic dynamos, like that responsible for the 11-year solar cycle, change with ro…
The First APOKASC Catalog of Kepler Dwarf and Subgiant Stars
Aldo Serenelli, Jennifer Johnson, Daniel Huber +23
(Abridged) We present the first APOKASC catalog of spectroscopic and asteroseismic data for 415 dwarfs and subgiants. Asteroseismic data have been obtained by Kepler in short caden…
The masses of retired A stars with asteroseismology: Kepler and K2 observations of exoplanet hosts
Thomas S. H. North, Tiago L. Campante, Andrea Miglio +7
We investigate the masses of "retired A stars" using asteroseismic detections on seven low-luminosity red-giant and sub-giant stars observed by the NASA Kepler and K2 Missions. Our…
Spatial incoherence of solar granulation: a global analysis using BiSON 2B data
Mikkel N. Lund, William J. Chaplin, Steven J. Hale +3
A poor understanding of the impact of convective turbulence in the outer layers of the Sun and Sun-like stars challenges the advance towards an improved understanding of their inte…
NGC 6819: testing the asteroseismic mass scale, mass loss, and evidence for products of non-standard evolution
R. Handberg, K. Brogaard, A. Miglio +5
We present an extensive peakbagging effort on Kepler data of 50 red giant stars in the open star cluster NGC 6819. By employing sophisticated pre-processing of the time serie…
Changing the Scaling Relation: The Need For a Mean Molecular Weight Term
Lucas S. Viani, Sarbani Basu, William J. Chaplin +2
The scaling relations that relate the average asteroseismic parameters and to the global properties of stars are used quite extensively to determine stellar propert…
Asteroseismology and Gaia: Testing Scaling Relations Using 2200 Kepler Stars with TGAS Parallaxes
Daniel Huber, Joel Zinn, Mathias Bojsen-Hansen +17
We present a comparison of parallaxes and radii from asteroseismology and Gaia DR1 (TGAS) for 2200 Kepler stars spanning from the main sequence to the red giant branch. We show tha…
Weighing in on the masses of retired A stars with asteroseismology: K2 observations of the exoplanet-host star HD 212771
Tiago L. Campante, Dimitri Veras, Thomas S. H. North +12
Doppler-based planet surveys point to an increasing occurrence rate of giant planets with stellar mass. Such surveys rely on evolved stars for a sample of intermediate-mass stars (…
Time-Series Analysis of Broadband Photometry of Neptune from K2
Jason F. Rowe, Patrick Gaulme, Jack J. Lissauer +19
We report here on our search for excess power in photometry of Neptune collected by the K2 mission that may be due to intrinsic global oscillations of the planet Neptune. To conduc…
Using red clump stars to correct the Gaia DR1 parallaxes
Guy R. Davies, Mikkel N. Lund, Andrea Miglio +14
Recent results have suggested that there is tension between the Gaia DR1 TGAS distances and the distances obtained using luminosities determined by eclipsing binaries or asteroseis…
