CH star A type of carbon star in which the molecular bands of CH are very strong. CH stars are also typically high-velocity Population II objects found in the galactic halo and in globular clusters. They were first identified as a distinct group by Philip Keenan (1908-) in 1942, a year after he and William Morgan developed their unified carbon star classification scheme (see Morgan-Keenan classification).
