Modeling Multi-Wavelength Stellar Astrometry. II. Determining Absolute Inclinations, Gravity Darkening Coefficients, and Spot Parameters of Single Stars with SIM Lite
Jeffrey L. Coughlin, Thomas E. Harrison, Dawn M. Gelino
We present a novel technique to determine the absolute inclination of single stars using multi-wavelength sub-milliarcsecond astrometry. The technique exploits the effect of gravit…
Low-Mass Eclipsing Binaries in the Initial Kepler Data Release
J. L. Coughlin, M. Lopez-Morales, T. E. Harrison +2
We identify 231 objects in the newly released Cycle 0 dataset from the Kepler Mission as double-eclipse, detached eclipsing binary systems with Teff < 5500 K and orbital periods sh…
Modeling Multi-Wavelength Stellar Astrometry. I. SIM Lite Observations of Interacting Binaries
Jeffrey L. Coughlin, Dawn M. Gelino, Thomas E. Harrison +6
Interacting binaries consist of a secondary star which fills or is very close to filling its Roche lobe, resulting in accretion onto the primary star, which is often, but not alway…
Observations and Models of Eclipsing Binary Systems: RT And, TU Boo, KV Gem, UU Lyn, MY Cyg, KR Per, RU Eri, and YY Cet
Jeffrey L. Coughlin
Eclipsing binary systems form the fundamental basis of Astronomy in the sense that they are the primary means to determine fundamental stellar astrophysical quantities such as mass…
