The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities
Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40
Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precisi…
EXPRES. III. Revealing the Stellar Activity Radial Velocity Signature of Eridani with Photometry and Interferometry
Rachael M. Roettenbacher, Samuel H. C. Cabot, Debra A. Fischer +20
The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) sh…
EXPRES. II. Searching for Planets Around Active Stars: A Case Study of HD 101501
Samuel H. C. Cabot, Rachael M. Roettenbacher, Gregory W. Henry +7
By controlling instrumental errors to below 10 cm/s, the EXtreme PREcision Spectrograph (EXPRES) allows for a more insightful study of photospheric velocities that can mask weak Ke…
EXPRES I. HD~3651 an Ideal RV Benchmark
John M. Brewer, Debra A. Fischer, Ryan T. Blackman +10
The next generation of exoplanet-hunting spectrographs should deliver up to an order of magnitude improvement in radial velocity precision over the standard 1 m/s state of the art.…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
An Extreme Precision Radial Velocity Pipeline: First Radial Velocities from EXPRES
Ryan R. Petersburg, J. M. Joel Ong, Lily L. Zhao +13
The EXtreme PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, , optical spectrograph. It was recently commissioned at the 4.3-m Lowell Discove…
