VizieR Online Data Catalog: K2-Gaia-ESO stellar param. and abundances (Worley+, 2020)

K2 C3 field targets were prepared as part of the Gaia-ESO observing programme and observed in May, June and October 2016. The resulting catalogue comprises 62 targets observed using the 580 setup of the UVES spectrograph (blue and red arms) and 28 targets using the HR10 and HR21 setups of the GIRAFFE spectrographs on the VLT.

Stellar parameters (Teff and [Fe/H]) and chemical abundances were determined by two Gaia-ESO nodes: Lumba (spectrum synthesis with Spectroscopy Made Easy (SME: Valenti & Piskunov 1996A&AS..118..595V; Piskunov & Valenti 2017A&A...597A..16P), and EPINARBO (equivalent width analysis using DOOp: Cantat-Gaudin et al. 2014A&A...562A..10C and FAMA: Magrini et al. 2014, MOOG Analysis, Astrophysics Source Code Library). Both methods use MARCS stellar atmosphere models (Gustafsson et al., 2008A&A...486..951G) and the Gaia-ESO linelist (Heiter et al., 2020, A&A, submitted). Seismic logg, as well as stellar age and mass, were determined from the K2 detections as described in Rendle et al. 2019.

These data comprise the final K2@Gaia-ESO Catalogue of 90 Red Giants and are presented Table B1.

The chemical abundances derived per spectral line per star per analysis node, including the spectral line atomic information and reference, are presented in Table B2.
