Abstract:
Since early 2015 a spectroscopic monitoring campaign of selected
Hipparcos stars is going on at the University Observatory Jena. The
aim of this project is to search for lithium at 6708Å, which is a
youth indicator, and to measure its equivalent width to identify young
runaway stars in the sample (age≤50Myr) along with the Gaia data.
Description:
Here, we present equivalent width measurements of the lithium 6708Å
line for 308 Hipparcos stars, taken between 2015 and 2018 at the
University Observatory Jena with the Echelle spectrograph FLECHAS.
Targets without significant detection of lithium are listed with " - ".
Furthermore, we publish the normalised spectra of each star with a
wavelength coverage between 6620 and 6820Å. All orders of the
fully reduced spectra are available upon request.
