A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
A new Hyper-Runaway star discovered from LAMOST and GAIA: ejected almost in the galactic rotation direction
Yin-Bi Li, A-Li Luo, Gang Zhao +11
In this paper, we report the discovery of a new late-B type unbound hyper-runaway star (LAMOST-HVS4) from the LAMOST spectroscopic surveys. According to its atmospheric parameters,…
NGC 1980 is not a foreground population of Orion: Spectroscopic survey of young stars with low extinction in Orion A
Min Fang, Jinyoung Serena Kim, Ilaria Pascucci +6
We perform a spectroscopic survey of the foreground population in Orion A with MMT/Hectospec. We use these data, along with archival spectroscopic data and photometric data, to der…
Chemical Composition of Young Stars in the Leading Arm of the Magellanic System
Lan Zhang, Christian Moni Bidin, Dana I. Casetti-Dinescu +6
Chemical abundances of eight O- and B-type stars are determined from high-resolution spectra obtained with the MIKE instrument on the Magellan 6.5m Clay telescope. The sample is se…
