Stellar Properties of KIC 8736245: An Eclipsing Binary with a Solar-type Star Leaving the Main Sequence
Tara Fetherolf, William F. Welsh, Jerome A. Orosz +5
There is a well-known stellar parameter discrepancy for late K and M dwarfs, in that the observed radii and temperatures are often respectively larger and cooler than predicted by…
Two New Long-Period Hot Subdwarf Binaries with Dwarf Companions
Brad N. Barlow, Sandra E. Liss, Richard A. Wade +1
Hot subdwarf stars with F-K main sequence binary companions have been known for decades, but the first orbital periods for such systems were published just recently. Current observ…
Kepler Studies of Low-Mass Eclipsing Binaries I. Parameters of the Long-Period Binary KIC 6131659
Gideon Bass, Jerome A. Orosz, William F. Welsh +5
KIC 6131659 is a long-period (17.5 days) eclipsing binary discovered by the Kepler mission. We analyzed six quarters of Kepler data along with supporting ground-based photometric a…
The Neptune-Sized Circumbinary Planet Kepler-38b
Jerome A. Orosz, William F. Welsh, Joshua A. Carter +28
We discuss the discovery and characterization of the circumbinary planet Kepler-38b. The stellar binary is single-lined, with a period of 18.8 days, and consists of a moderately ev…
A Radial Velocity Study of Composite-Spectra Hot Subdwarf Stars with the Hobby-Eberly Telescope
Brad N. Barlow, Richard A. Wade, Sandra E. Liss +2
Many hot subdwarf stars show composite spectral energy distributions indicative of cool main sequence companions. Binary population synthesis (BPS) models demonstrate such systems…
The Rømer Delay and Mass Ratio of the sdB+dM Binary 2M 1938+4603 from Kepler Eclipse Timings
Brad N. Barlow, Richard A. Wade, Sandra E. Liss
The eclipsing binary system 2M 1938+4603 consists of a pulsating hot subdwarf B star and a cool M dwarf companion in an effectively circular three-hour orbit. The light curve shows…
