LAMOST medium-resolution spectroscopic survey of binarity and exotic star (LAMOST-MRS-B): Observation strategy and target selection
Jiao Li, Jiang-Dan Li, Yan-Jun Guo +15
LAMOST-MRS-B is one of the sub-surveys of LAMOST medium-resolution (R~7500) spectroscopic survey. It aims at studying the statistical properties (e.g., binary fraction, orbital per…
A Roche Lobe-filling hot Subdwarf and White Dwarf Binary: possible detection of an ejected common envelope
Jiangdan Li, Christopher A. Onken, Christian Wolf +12
Binaries consisting of a hot subdwarf star and an accreting white dwarf (WD) are sources of gravitational wave radiation at low frequencies and possible progenitors of type Ia supe…
Mass-Ratio Distribution of Binaries From the LAMOST-MRS Survey
Jiangdan Li, Jiao Li, Chao Liu +7
Binary evolution leads to the formation of important objects crucial to the development of astrophysics, but the statistical properties of binary populations are still poorly under…
TYC~2990-127-1: an Algol-type SB2 binary system of subgiant and red giant with a probable ongoing mass-transfer
Mikhail Kovalev, Zhenwei Li, Xiaobin Zhang +3
We present a study of the spectroscopic binary TYC 2990-127-1 from the LAMOST survey. We use full-spectrum fitting to derive radial velocities and spectral parameters. The high mas…
