Abstract
We present the stellar velocity dispersion measurements for five luminous compact galaxies (LCGs) at z= 0.5–0.7. These galaxies are vigorously forming stars with an average star formation rate of ∼40 M⊙ yr−1. We find that their velocity dispersions range from ∼137 to 260 km s−1, while their stellar masses range from 4 × 109 to 1011 M⊙. 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.
