Stellar Proper Motions in the Orion Nebula Cluster
Dongwon Kim, Jessica R. Lu, Quinn Konopacky +5
The Orion Nebula Cluster (ONC) is the nearest site of ongoing massive star formation, which allows us to study the kinematics and dynamics of the region in detail and constrain sta…
On the Nature of Ultra-faint Dwarf Galaxy Candidates. III. Horologium I, Pictor I, Grus I, and Phoenix II
Helmut Jerjen, Blair Conn, Dongwon Kim +1
We use deep Gemini/GMOS-S photometry to study the stellar populations of the recently discovered Milky Way satellite candidates Horologium I, Pictor I, Grus I, and Phoenix II…
RR Lyrae Variable Stars in the Crater II Dwarf Galaxy
Seok-Joo Joo, Jaemann Kyeong, Soung-Chul Yang +10
We report the detection of RR Lyrae variable stars in Crater II, a recently discovered large and diffuse satellite dwarf galaxy of the Milky Way (MW). Based on B, V time-series pho…
Chemical Abundances of new member stars in the Tucana II dwarf galaxy
Anirudh Chiti, Anna Frebel, Alexander P. Ji +3
We present chemical abundance measurements for seven stars with metallicities ranging from [Fe/H] = 3.3 to [Fe/H] = 2.4 in the Tucana II ultra-faint dwarf galaxy (UFD), based…
On The Nature of ultra-faint Dwarf Galaxy Candidates II: The case of Cetus II
Blair C. Conn, Helmut Jerjen, Dongwon Kim +1
We obtained deep Gemini GMOS-S photometry of the ultra-faint dwarf galaxy candidate Cetus II with the aim of providing stronger constraints on its size, luminosity and stella…
