BANYAN. III. RADIAL VELOCITY, ROTATION, AND X-RAY EMISSION OF LOW-MASS STAR CANDIDATES IN NEARBY YOUNG KINEMATIC GROUPS [PDF]
, 2014 Based on high-resolution spectra obtained with PHOENIX at Gemini-South, CRIRES at VLT-UT1, and ESPaDOnS at the Canada–France–Hawaii Telescope, we present new measurements of the radial and projected rotational velocities of 219 low-mass stars. The target

An astro-comb calibrated solar telescope to search for the radial velocity signature of Venus
Astronomical Telescopes + Instrumentation, 2016 We recently demonstrated sub-m/s sensitivity in measuring the radial velocity (RV) between the Earth and Sun using a simple solar telescope feeding the HARPS-N spectrograph at the Italian National Telescope, which is calibrated with a green astro-comb ...

Radial velocities for the Hipparcos-Gaia Hundred-Thousand-Proper-Motion project
, 2012 (abridged) The Hundred-Thousand-Proper-Motion (HTPM) project will determine the proper motions of ~113500 stars using a 23-year baseline. The proper motions will use the Hipparcos data, with epoch 1991.25, as first epoch and the first intermediate ...
