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.…
Photon-weighted barycentric correction and its importance for precise radial velocities
René Tronsgaard, Lars A. Buchhave, Jason T. Wright +2
When applying the barycentric correction to a precise radial velocity measurement, it is common practice to calculate its value only at the photon-weighted midpoint time of the obs…
The Measured Impact of Chromatic Atmospheric Effects on Barycentric Corrections: Results from the EXtreme PREcision Spectrograph
Ryan Blackman, Joel Ong, Debra Fischer
One source of error in high-precision radial velocity measurements of exoplanet host stars is chromatic change in Earth's atmospheric transmission during observations. Mitigation o…
Accounting for Chromatic Atmospheric Effects on Barycentric Corrections
Ryan T. Blackman, Andrew E. Szymkowiak, Debra A. Fischer +1
Atmospheric effects on stellar radial velocity measurements for exoplanet discovery and characterization have not yet been fully investigated for extreme precision levels. We carry…
