A better understanding of the AM CVn population is crucial to constrain their candidacy as SN Ia progenitors, to test binary evolution (in particular the common-envelope phase), and to predict their observable gravitational radiation signature. An AM CVn dedicated search in the Sloan Digital Sky Survey-DRl resulted in the discovery of SDSS J124058.03-015919.2, a new AM CVn candidate previously identified as a DB white dwarf in the 2dF quasar survey.
