Detection of p-mode Oscillations in HD 35833 with NEID and TESS
Arvind F. Gupta, Jacob K. Luhn, Jason T. Wright +15
We report the results of observations of p-mode oscillations in the G0 subgiant star HD 35833 in both radial velocities and photometry with NEID and TESS, respectively. We achieve…
Modeling Stellar Oscillations and Granulation in Radial Velocity Time Series: A Fourier-based Method
Zhao Guo, Eric B. Ford, Dennis Stello +4
Tens of thousands of solar-like oscillating stars have been observed by space missions. Their photometric variability in the Fourier domain can be parameterized by a sum of two sup…
: Distinguishing Planet-induced Doppler Signatures from Granulation with a Synthetic Spectra Generator
Michael L. Palumbo, Eric B. Ford, Jason T. Wright +3
Owing to recent advances in radial-velocity instrumentation and observation techniques, the detection of Earth-mass planets around Sun-like stars may soon be primarily limited by i…
Persistent starspot signals on M dwarfs: multi-wavelength Doppler observations with the Habitable-zone Planet Finder and Keck/HIRES
Paul Robertson, Gudmundur Stefansson, Suvrath Mahadevan +23
Young, rapidly-rotating M dwarfs exhibit prominent starspots, which create quasiperiodic signals in their photometric and Doppler spectroscopic measurements. The periodic Doppler s…
Time variation of Kepler transits induced by stellar spots - a way to distinguish between prograde and retrograde motion. II. Application to KOIs
Tomer Holczer, Avi Shporer, Tsevi Mazeh +8
Mazeh, Holczer, and Shporer (2015) have presented an approach that can, in principle, use the derived transit timing variation (TTV) of some transiting planets observed by the $Kep…
Kepler's Unparalleled Exploration of the Time Dimension
William Welsh, Steven Bloemen, Kyle Conroy +15
We show that the Kepler spacecraft in two-reaction wheel mode of operation is very well suited for the study of eclipsing binary star systems. Continued observations of the Kepler…
