Subdwarfs: Kinematics, Galactic Disk, Luminosity Function
Scientific paper
We present an analysis of the space motions of 740 subdwarf stars based on the sample stars of Carney et al. (1994; CLLA). Hipparcos parallaxes and proper motion and Tycho2 proper motions were combined with radial velocities and metallicities from CLLA. The kinematical behavior is discussed in particular in relation to their metallicities. For stars with metallicity -1.0<[Fe/H]<-0.4, the velocity distribution represent the thick disk population. We derived the luminosity function of thick disk using 1/Vmax method. We found that the luminosity function in absolute magnitude of MV = 4 - 5 mag, agree well with the Luminosity function derived from the stellar initial function (Reyle & Robin 2001). We analayzed the kinematics in our thick disk sample and found substructure in the thick disk population.
