Witnessing the star-formation quenching in $L_{}$ ellipticals
We study the evolution of $L_{*}$ elliptical galaxies in the color-magnitude diagram in terms of their star-formation history and environment, in an attempt to learn about their quenching process.

| Zusammenfassung: | We study the evolution of $L_{*}$ elliptical galaxies in the color-magnitude
diagram in terms of their star-formation history and environment, in an attempt
to learn about their quenching process. We have visually extracted 1109 $L_{*}$
galaxies from a sample of 36500 galaxies that were spectroscopically selected
from Stripe82 of the Sloan Digital Sky Survey. From this sample we have
selected 51 ellipticals based on their surface-brightness profile being
well-fitted by a single S$\acute{e}$rsic profile with S$\acute{e}$rsic indices
