Abstract

We present the stellar velocity dispersion measurements for 5 Luminous Compact Galaxies (LCGs) at z=0.5-0.7. These galaxies are vigorously forming stars with average SFR \sim 40 M_{\odot}/yr. We find that their velocity dispersions range from 137 km/s\sim137\ \rm{km/s} to 260 km/s260\ \rm{km/s}, while their stellar masses range between 4×1094\times 10^{9} and 101110^{11} M_{\odot}. If these LCGs evolve passively after this major burst of star formation, their masses and velocity dispersions, as well as their evolved colours and luminosities are most consistent with the values characteristic of early-type spiral galaxies today.
