In this work we have studied the properties of 51 early type L* galaxies in Stripe 82 using SDSS coadded data, which is ∼ 1.5 - 2 magnitude deeper than the SDSS single frame images. L* galaxies are bright galaxies, comparable in mass to the Milky Way and occupy the knee region of the Schechter luminosity function. However, occupying a narrow mass range, L* galaxies are observed to have extremely wide range in morphology and properties. Based on the study of active star forming blue and quenched red L* ellipticals, we find that L* ellipticals evolve via star-formation quenching without much transformation in morphology. |
