Red supergiant stars in IC 1613 and metallicity-dependent mixing length in the evolutionary model
Sang-Hyun Chun, Sung-Chul Yoon, Heeyoung Oh +2
We report a spectroscopic study on red supergiant stars (RSGs) in the irregular dwarf galaxy IC 1613 in the Local Group. We derive the effective temperatures () and…
High-resolution Near-infrared Spectroscopy of Diffuse Sources around MWC 1080
Il-Joong Kim, Heeyoung Oh, Woong-Seob Jeong +3
To reveal the origins of diffuse H-alpha emissions observed around the Herbig star MWC 1080, we have performed a high-resolution near-infrared (NIR) spectroscopic observation using…
IGRINS RV: A Precision RV Pipeline for IGRINS Using Modified Forward Modeling in the Near-Infrared
Asa G. Stahl, Shih-Yun Tang, Christopher M. Johns-Krull +7
Application of the radial velocity (RV) technique in the near infrared is valuable because of the diminished impact of stellar activity at longer wavelengths, making it particularl…
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…
IGRINS Slit-Viewing Camera Software
Hye-In Lee, Soojong Pak, Gregory N. Mace +5
We have developed observation control software for the Immersion GRating INfrared Spectrometer (IGRINS) slit-viewing camera module, which maintains the position of an astronomical…
Detection of Pristine Circumstellar Material of the Cassiopeia A Supernova
Bon-Chul Koo, Hyun-Jeong Kim, Heeyoung Oh +4
Cassiopeia A is a nearby young supernova remnant that provides a unique laboratory for the study of core-collapse supernova explosions. Cassiopeia A is known to be a Type IIb super…
