The main sequence dwarf carbon (dC) stars have inherited carbon-rich material from an AGB companion, which has since transitioned to a white dwarf. The dC stars are far more common than C giants, but no reliable estimates of dC space density have been published to date. We present results from an all-sky survey for carbon stars using the low-resolution XP spectra from Gaia DR3. We developed and measured a set of spectral indices contrasting C$_{\\rm 2}","authors_text":"(2) University of California, (3) Center for Astrophysics | Harvard & Smithsonian, (4) California Institute of Technology), Benjamin R.
