Abstract:
* Aims: We present a compilation of spectroscopic data from a survey of
144 chromospherically active young stars in the solar neighborhood
which may be used to investigate different aspects of the formation
and evolution of the solar neighborhood in terms of kinematics and
stellar formation history. The data have already been used by us in
several studies. With this paper, we make all these data accessible to
the scientific community for future studies on different topics.
* Methods: We performed spectroscopic observations with echelle
spectrographs to cover the entirety of the optical spectral range
simultaneously. Standard data reduction was performed with the IRAF
echelle package. We applied the spectral subtraction technique to
reveal chromospheric emission in the stars of the sample. The
equivalent width of chromospheric emission lines was measured in the
subtracted spectra and then converted to fluxes using equivalent
width--flux relationships. Radial and rotational velocities were
determined by the cross-correlation technique. Kinematics, equivalent
widths of the lithium line 6707.8Å and spectral types were also
determined.
* Results: A catalog of spectroscopic data is compiled: radial and
rotational velocities, space motion, equivalent widths of optical
chromospheric activity indicators from Ca II H & K to the calcium
infrared triplet and the lithium line in 6708Å. Fluxes in the
chromospheric emission lines and R'_HK are also determined for each
observation of star in the sample. We used these data to investigate
the emission levels of our stars. The study of the Hα emission
line revealed the presence of two different populations of
chromospheric emitters in the sample, clearly separated in the
log(FHα/Fbol)-(V-J) diagram. The dichotomy may be
associated with the age of the stars.
