A homogeneous view of asymptotic giant branch carbon stars as seen by Gaia
Alessio Liberatori, Despina Hatzidimitriou, Konstantinos Antoniadis +12
Carbon stars on the asymptotic giant branch are major contributors to galactic dust enrichment, with gas mass-loss rates up to 1e-4 Msun/yr. We present a homogeneous spectral energ…
