Carbon Stars From Gaia DR3 and the Space Density of Dwarf Carbon Stars
Benjamin R. Roulston, Naunet Leonhardes-Barboza, Paul J. Green +1
Carbon stars (with atmospheric C/O) range widely in temperature and luminosity, from low mass dwarfs to asymptotic giant branch stars (AGB). The main sequence dwarf carbon (dC)…
