The Binary Fraction of Stars in the Dwarf Galaxy Ursa Minor via Dark Energy Spectroscopic Instrument

Tian Qiu, Wenting Wang, Sergey Koposov +45

We utilize multi-epoch line-of-sight velocity measurements from the Milky Way Survey of the Dark Energy Spectroscopic Instrument to estimate the binary fraction for member stars in…

New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling

Irene Vargas-Salazar, M. S. Oey, Jan J. Eldridge +9

We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS mult…

Distribution and Kinematics of H I through Raman He II Spectroscopy of NGC 6302

Seok-Jun Chang, Hee-Won Lee, Jiyu Kim +1

The young planetary nebula NGC 6302 is known to exhibit Raman-scattered He II features at 6545 and 4851 Angstrom. These features are formed through inelastic scattering of He II$λλ…

The Sejong Open Cluster Survey (SOS). VII. A Photometric Study of the Young Open Cluster IC 1590

Seulgi Kim, Beomdu Lim, Michael S. Bessell +2

Young open clusters are ideal laboratories to understand star formation process. We present deep UBV I and Halpha photometry for the young open cluster IC 1590 in the center of the…

Raman-scattered O VI features in the symbiotic nova RR Telescopii

Jeong-Eun Heo, Hee-Won Lee, Rodolfo Angeloni +2

RR Tel is an interacting binary system in which a hot white dwarf (WD) accretes matter from a Mira-type variable star via gravitational capture of its stellar wind. This symbiotic…

Discovery of Raman-scattered He II 6545 in the Planetary Nebulae NGC 6886 and NGC 6881

Bo-Eun Choi, Hee-Won Lee

Young planetary nebulae (PNe) retain a large amount of neutral material that was shed in the previous asymptotic giant branch stage. The thick H I region in young PNe can be effect…
