Differential Modelling Systematics across the HR Diagram from Asteroseismic Surface Corrections
J. M. Joel Ong, Sarbani Basu, Jean M. McKeever
Localised modelling error in the near-surface layers of evolutionary stellar models causes the frequencies of their normal modes of oscillation to differ from those of actual stars…
Active red giants: close binaries versus single rapid rotators
Patrick Gaulme, Jason Jackiewicz, Federico Spada +7
The objective of this work is to determine what fraction of red-giant (RG) stars shows photometric rotational modulation, and understand its origin. One of the underlying questions…
The Helium Abundance of NGC 6791 from Modeling of Stellar Oscillations
Jean McKeever, Sarbani Basu, Enrico Corsaro
The helium abundance of stars is a strong driver of evolutionary timescales, however it is difficult to measure in cool stars. We conduct an asteroseismic analysis of NGC 6791, an…
Modeling Radial Velocities and Eclipse Photometry of the Kepler Target KIC 4054905: an Oscillating Red Giant in an Eclipsing Binary
M. Benbakoura, P. Gaulme, J. McKeever +3
Asteroseismology is a powerful tool to measure the fundamental properties of stars and probe their interiors. This is particularly efficient for red giants because their modes are…
Testing the asteroseismic scaling relations for Red Giants with Eclipsing Binaries Observed by Kepler
Patrick Gaulme, Jean McKeever, Jason Jackiewicz +7
Given the potential of ensemble asteroseismology for understanding fundamental properties of large numbers of stars, it is critical to determine the accuracy of the scaling relatio…
KIC 9246715: The Double Red Giant Eclipsing Binary With Odd Oscillations
Meredith L. Rawls, Patrick Gaulme, Jean McKeever +7
We combine Kepler photometry with ground-based spectra to present a comprehensive dynamical model of the double red giant eclipsing binary KIC 9246715. While the two stars are very…
Two new SB2 binaries with main sequence B-type pulsators in the Kepler field
P. I. Pápics, A. Tkachenko, C. Aerts +15
Context: OB stars are important in the chemistry and evolution of the Universe, but the sample of targets well understood from an asteroseismological point of view is still too lim…
Red Giants in Eclipsing Binary and Multiple-Star Systems: Modeling and Asteroseismic Analysis of 70 Candidates from Kepler Data
Patrick Gaulme, Jean Mc Keever, Meredith L. Rawls +3
Red-giant stars are an incredible source of information for testing models of stellar evolution, as asteroseismology has opened up a window into their interiors. Such insights are…
The Classificiation of Kepler B star Variables
Bernard J. McNamara, Jason Jackiewicz, Jean McKeever
The light curves of 252 B-star candidates in the Kepler data base are analyzed in a similar fashion to that done by Balona et al. (2011) to further characterize B star variability,…
