VizieR Online Data Catalog: Transit parameters for planets around subgiants (Luhn+, 2019)
Abstract
Our sample is composed of stars observed as part of the California Planet Search (CPS) with 3.0<logg<4.0. From this sample of over 400 stars, we have identified those that are known to host planets, as identified in either www.exoplanets.org or www.exoplanet.eu. Observations were taken at Keck Observatory using the High Resolution Echelle Spectrometer (HIRES) with a resolution of R~55000. For a V=8 magnitude star, the exposure required is 90 s to reach a signal-to-noise ratio of 190 at 5800 Å. RVs are calculated using the iodine-cell calibration technique and the forward-modeling procedure described in Butler et al. (1996PASP..108..500B) and later Howard et al. (2011ApJ...726...73H). For several stars that were known planet hosts, we included the non-Keck RV measurements as published with the planet discovery.
