VizieR Online Data Catalog: Chromospheric activity from AMBRE-HARPS (Gomes da Silva+, 2021)
Abstract
We present a catalogue of 1674 FGK MS, subgiant, and giant stars with more than 180 000 observations from the HARPS archive taken between 2003 and 2019. The vast majority of the stars are in the solar neighbourhood at less than 100pc away. The catalogue has a maximum time-span of ~15.5 years. We have 428 stars with an observation time-span longer than 10 years, 178 of them with more than 50 individual nights of observation. These stars with long time-spans (and therefore high-accuracy median activity levels) constitute a prime sample with which to study stellar rotation, cycles, and evolution. These time series will be reported in the following papers of this series.
