Abstract:
One of the main scientific drivers for ESPRESSO, Echelle
SPectrograph, is the detection and characterization of Earth-class
exoplanets. With this goal in mind, the ESPRESSO guaranteed time
observations (GTO) Catalog identifies the best target stars for a
blind search for the radial velocity (RV) signals caused by
Earth-class exoplanets.
Using the most complete stellar catalogs available, we screened for
the most suitable G, K, and M dwarf stars for the detection of
Earth-class exoplanets with ESPRESSO. For most of the stars, we then
gathered high-resolution spectra from new observations or from
archival data. We used these spectra to spectroscopically investigate
the existence of any stellar binaries, both bound or background stars.
We derived the activity level using chromospheric activity indexes
using log (R'HK), as well as the projected rotational velocity
vsini. For the cases where planet companions are already known, we
also looked at the possibility that additional planets may exist in
the host's habitable zone using dynamical arguments.
We estimated the spectroscopic contamination level, vsini, activity,
stellar parameters and chemical abundances for 249 of the most
promising targets. Using these data, we selected 45 stars that match
our criteria for detectability of a planet like Earth. The stars
presented and discussed in this paper constitute the ESPRESSO GTO
catalog for the RV blind search for Earth-class planets. They can also
be used for any other work requiring a detailed spectroscopic
characterization of stars in the solar neighborhood.
Description:
The tables contain the spectroscopic stellar parameters and chemical
abundances derived for the stars which have described in the paper.
