A catalog of new slowly pulsating B-type stars
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +1
This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of TESS, LAMOST, and Gaia surveys, we have found 286…
New evidence for the precession of tilted disk in SDSS J081256.85+191157.8
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +5
Super-orbital signals and negative superhumps are thought to be related to the reverse precession of the nodal line in a tilted disk, but the evidence is lacking. Our results provi…
First discovery of QPOs in the dwarf nova HS 2325+8205 based on TESS photometry
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +9
HS 2325+8205 is a long-period eclipsing dwarf nova with an orbital period above the period gap (Porb>3 h) and is reported to be a Z Cam-type dwarf nova. Based on the photometry of…
Chemically Peculiar Stars in Integrated Light Stellar Population Models and Local Group Galaxies
Guy Worthey, Xiang Shi
Integrated-light models that incorporate common types of chemically peculiar (CP) stars are assembled using synthetic spectra. Selected spectral features encode significant age inf…
Individual element sensitivity for stellar evolutionary isochrones
Guy Worthey, Xiang Shi, Tathagata Pal +2
Stellar evolution calculations with variable abundance ratios were used to gauge the effects on temperatures, luminosities, and lifetimes in various phases. Individual elements C,…
ASAS J174406+2446.8 is identified as a marginal-contact binary with a possible cool third body
Xiang-Dong Shi, Sheng-Bang Qian, Lin-Jia +2
ASAS J174406+2446.8 was originally found as a Scuti-type pulsating star with the period P=0.189068 by ASAS survey. However, the LAMOST stellar parameters reveal that it…
