HIRES/Keck radial velocity database
Listed in IVOA Registry (Virtual Observatory)
The first HIRES/Keck precision radial velocity (RV) catalog was released in 2017, followed by a second release in 2019, incorporating corrections for minor but significant systematic errors.
Description
We have expanded this catalog to March 2023, with 17971 RV measurements for 1702 stars. Furthermore, we have included the chromospheric emission lines CaII H&K indicator (R'HK), which is among the most prominent tracers of stellar activity.
The manifestation of stellar activity, accompanied by minor systematic errors in high-resolution optical stellar spectra, could affect exoplanets detected by the RV method. We provide R'HK measurements for~40% of the HIRES catalog alongside RVs to mitigate these effects. The precision RVs were obtained using an iodine gas absorption cell, and relative, chromospheric emissions at the CaII H&K lines were derived from the same spectra used for RV measurements.

The emitted flux was extracted by rectifying the observed spectra with PHOENIX synthetic models across six narrow bands surrounding the H and K lines, followed by the subtraction of the photospheric contribution. The updated catalog may help distinguish stellar activity effects from planetary signals in RV time series, corroborating previously detected planetary candidates and aiding the detection of new ones.
