lithium star
subject			fact

lithium star	has spectral type G star, M star
	has definition C star with a very strong Li I 6078 line.
	has definition Peculiar giant star (spectral types G-M) whose spectra show high abundances of lithium. They are primarily S stars and carbon stars, although Li is also found in T Tauri stars, and is sometimes observed in normal late-type giants. Interstellar Li / H ≈ 2 × 10-10. (Solar system Li / H ≈ 10-9.) Lithium is destroyed rapidly (in about 7500 years) at typical nuclear burning temperatures. Spallation is the only production mechanism known for 6Li, but 7Li can be transported from the core in the form of 7Be and converted in the envelope to 7Li by electron capture. Observed 7Li / 6Li > 10.
