Carbon-Enhanced Dwarf Stars Are Predominantly a Halo Population
Jay Farihi, Jason L. Sanders, Sophia Lilleengen +2
This paper reports a Galactic kinematical and dynamical analysis of 1003 main-sequence carbon stars. The sample is drawn from the Sloan Digital Sky Survey, and cross-matched with G…

Carbon-enhanced stars with short orbital and spin periods
L. J. Whitehouse, J. Farihi, I. D. Howarth +5
Many characteristics of dwarf carbon stars are broadly consistent with a binary origin, including mass transfer from an evolved companion. While the population overall appears to h…

Dwarf carbon stars are likely metal-poor binaries and unlikely hosts to carbon planets
Lewis J. Whitehouse, J. Farihi, P. J. Green +2
Dwarf carbon stars make up the largest fraction of carbon stars in the Galaxy with around 1200 candidates known to date primarily from the Sloan Digital Sky Survey. They either pos…
