M67 Blue Stragglers with High-resolution Infrared Spectroscopy
K. E. Brady, C. Sneden, C. A. Pilachowski +5
We report on the first detailed infrared chemical analysis of five binary members (S277, S997, S975, S1031, and S1195) in the open cluster M67 (NGC 2682). These stars are located o…
A Gigantic Mid-Infrared Outburst in an Embedded Class-I Young Stellar Object J064722.95+031644.6
Tinggui Wang, Jiaxun Li, Gregory M. Mace +4
We report the serendipitous discovery of a giant mid-infrared (MIR) outburst from a previously unknown source near a star-forming region in the constellation Monoceros. The source…
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…
M giants with IGRINS I. Stellar parameters and -abundance trends of the solar neighborhood population
G. Nandakumar, N. Ryde, L. Casagrande +1
Cool stars, such as M giants, can only be analysed in the near-infrared (NIR) regime due to the ubiquitous TiO features in optical spectra of stars with Teff < 4000 K. In dust obsc…
Effective Temperature Estimations from Line Depth Ratios in the \H\ and \K-band Spectra of IGRINS
Melike Afşar, Zeynep Bozkurt, Gamze Böcek Topcu +5
Determining accurate effective temperatures of stars buried in the dust-obscured Galactic regions is extremely difficult from photometry. Fortunately, high-resolution infrared spec…
The IGRINS YSO Survey III: Stellar parameters of pre-main sequence stars in Ophiuchus and Upper Scorpius
Ricardo López-Valdivia, Gregory N. Mace, Eunkyu Han +9
We used the Immersion GRating Infrared Spectrometer (IGRINS) to determine fundamental parameters for 61 K- and M-type young stellar objects (YSOs) located in the Ophiuchus and Uppe…
