M Giants with IGRINS II. Chemical Evolution of Fluorine at High Metallicities
G. Nandakumar, N. Ryde, G. Mace
The origin and evolution of fluorine in the Milky Way galaxy is still in debate. In particular, the increase of the [F/Fe] in metal-rich stars found from near-IR HF-lines is challe…
The Transition from Diffuse Molecular Gas to Molecular Cloud Material in Taurus
S. R. Federman, Johnathan S. Rice, A. M. Ritchey +6
We study four lines of sight that probe the transition from diffuse molecular gas to molecular cloud material in Taurus. Measurements of atomic and molecular absorption are used to…
Fluorine in the solar neighbourhood: the need for several cosmic sources
Nils Ryde, Henrik Jönsson, Gregory Mace +14
The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constr…
High-resolution near-IR Spectral mapping with H and [Fe II] lines of Multiple Outflows around LkH 234
Heeyoung Oh, Tae-Soo Pyo, Bon-Chul Koo +11
We present a high-resolution, near-IR spectroscopic study of multiple outflows in the LkH 234 star formation region using the Immersion GRating INfrared Spectrometer (IGRINS). S…
