Formation of A Nuclear Star Cluster Through A Merger Event In The Low Surface Brightness Galaxy AGC 223218
Tian-Wen Cao, Zi-Qi Chen, Zi-Jian Li +8
We present the properties of the nuclear star cluster (NSC) in the low surface brightness galaxy AGC 223218. The disk of the galaxy can be modeled using two Srsic co…
Ionized gas components in low surface brightness galaxy AGC 111629
Tian-Wen Cao, Pei-Bin Chen, Zi-Jian Li +8
We present integral field spectroscopy of ionized gas components in AGC 111629, an edge-on low surface brightness galaxy (LSBG) with a stellar mass of 5.710 M$_{\odot…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Inside the Iron Curtain: A Long Term Look at the Iron Stars XX Oph and AS 325
Steve B. Howell, Venu M. Kalari, Andy Adamson +1
The Iron Stars XX Oph and AS 325, both binaries consisting of a Be + late K,M II star present remarkable optical spectra. Low velocity, dense winds from the late type star collide…
Dense clumps survive in the vicinity of R136 in 30 Doradus
M. T. Valdivia-Mena, M. Rubio, V. M. Kalari +5
Context: The young massive cluster R136 at the center of 30 Doradus (30 Dor) in the Large Magellanic Cloud (LMC) generates a cavity in the surrounding molecular cloud. However, the…
GHOST commissioning science results -- IV: Chemodynamical analyses of Milky Way satellites Sagittarius II and Aquarius II
Daria Zaremba, Kim Venn, Christian R. Hayes +28
We present Gemini/GHOST high-resolution spectra of five stars observed in two low surface brightness Milky Way satellites, Sagittarius II (Sgr2) and Aquarius II (Aqu2). For Aqu2, t…
