Variability at the Edge: Optical Near/IR Rapid Cadence Monitoring of Newly Outbursting FU Orionis Object HBC 722
Joel D. Green, Paul Robertson, Giseon Baek +7
We present the detection of day-timescale periodic variability in the r-band lightcurve of newly outbursting FU Orionis-type object HBC 722, taken from > 42 nights of observation w…
H-alpha Activity of Old M Dwarfs: Stellar Cycles and Mean Activity Levels For 93 Low-Mass Stars in the Solar Neighborhood
Paul Robertson, Michael Endl, William D. Cochran +1
Through the McDonald Observatory M Dwarf Planet Search, we have acquired nearly 3,000 high-resolution spectra of 93 late-type (K5-M5) stars over more than a decade using HET/HRS. T…
Relationship between low and high frequencies in Delta Scuti stars: Photometric Kepler and spectroscopic analyses of the rapid rotator KIC 8054146
M. Breger, L. Fossati, L. Balona +9
Two years of Kepler data of KIC 8054146 (delta Sct/gamma Dor hybrid) revealed 349 statistically significant frequencies between 0.54 and 191.36 c/d (6.3 microHz to 2.21 mHz). The 1…
Revisiting rho 1 Cancri e: A New Mass Determination Of The Transiting super-Earth
Michael Endl, Paul Robertson, William D. Cochran +6
We present a mass determination for the transiting super-Earth rho 1 Cancri e based on nearly 700 precise radial velocity (RV) measurements. This extensive RV data set consists of…
A Second Giant Planet in 3:2 Mean-Motion Resonance in the HD 204313 System
Paul Robertson, J. Horner, Robert A. Wittenmyer +7
We present 8 years of high-precision radial velocity (RV) data for HD 204313 from the 2.7 m Harlan J. Smith Telescope at McDonald Observatory. The star is known to have a giant pla…
The Transiting Circumbinary Planets Kepler-34 and Kepler-35
William F. Welsh, Jerome A. Orosz, Joshua A. Carter +43
Most Sun-like stars in the Galaxy reside in gravitationally-bound pairs of stars called "binary stars". While long anticipated, the existence of a "circumbinary planet" orbiting su…
