Weak-CN Stars Are Ordinary Cool Red Supergiants
Yuan-Sen Ting, Puragra Guhathakurta, Douglas Grion Filho +2
Weak CN absorption near ~8000 A has recently been detected in evolved red supergiants (RSGs) of 5-10 across three Local Group galaxies. These weak-CN RSGs sit in a narrow…
Discovery of a Weak CN Spectral Absorption Feature in Red Supergiant Stars in the Andromeda (M31) and Triangulum (M33) Galaxies
Puragra Guhathakurta, Douglas Grion Filho, Antara R. Bhattacharya +14
Using Keck DEIMOS spectra of stars in the Andromeda (M31) and Triangulum (M33) galaxies, selected from the large multi-band (near ultraviolet, visible light, and near infrared) Hub…
LAMOST J1010+2358 is not a Pair-Instability Supernova Relic
Pierre N. Thibodeaux, Alexander P. Ji, William Cerny +2
The discovery of a star formed out of pair-instability supernova ejecta would have massive implications for the Population III star initial mass function and the existence of stars…
