Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
TESS first look at evolved compact pulsators : Discovery and asteroseismic probing of the g-mode hot B subdwarf pulsator EC 21494-7018
S. Charpinet, P. Brassard, G. Fontaine +29
We present the discovery and asteroseismic analysis of a new g-mode hot B subdwarf (sdB) pulsator, EC 21494-7018 (TIC 278659026), monitored in TESS first sector using 120-second ca…
Ensemble asteroseismology of pulsating B-type stars in NGC 6910
D. Moździerski, A. Pigulski, Z. Kołaczkowski +24
Asteroseismology offers the possibility of probing stellar interiors and testing evolutionary and seismic models. Precise photometry and spectroscopy obtained during multi-site cam…
A New Luminous blue variable in the outskirt of the Andromeda Galaxy
Yang Huang, Huaiwei Zhang, Chun Wang +8
The hot massive luminous blue variables (LBVs) represent an important evolutionary phase of massive stars. Here, we report the discovery of a new LBV -- LAMOST J0037+4016 in the di…
Properties of Radial Velocities measurement based on LAMOST-II Medium-Resolution Spectroscopic Observations
R. Wang, A. -L. Luo, J. -J. Chen +28
The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolu…
Evolved Massive Stars at Low-metallicity I. A Source Catalog for the Small Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Bi-Wei Jiang +9
We present a clean, magnitude-limited (IRAC1 or WISE1 15.0 mag) multiwavelength source catalog for the SMC with 45,466 targets in total, with the purpose of building an anch…
An optical and X-ray study of the contact binary, BH Cassiopeiae
Junhui Liu, Ali Esamdin, Yu Zhang +10
We present the revised and high quality CCD time series observations in 2017 and 2018 of the W UMa-type contact binary BH~Cas. The combination of our new determinations of minimum…
Pulsations of the SX Phe Star BL Camelopardalis
Peng Zong, Ali Esamdin, Jian Ning Fu +6
We carried out photometric observations of the SX Phe star BL Cam in 2014, 2017 and 2018 using Nanshan 1-m telescope. In addition to the dominated frequency of 25.5790(3) cd…
Precise determination of stellar parameters of the ZZ Ceti and DAZ white dwarf GD 133 through asteroseismology
J. -N. Fu, G. Vauclair, J. Su +15
An increasing number of white dwarf stars show atmospheric chemical composition polluted by heavy elements accreted from debris disk material. The existence of such debris disks st…
The Period-Luminosity Relations of Red Supergiants in M33 and M31
Yi Ren, B. W. Jiang, Ming Yang +1
Based on previously selected preliminary samples of Red Supergiants (RSGs) in M33 and M31, the foreground stars and luminous Asymptotic Giant Branch stars (AGBs) are further exclud…
Rotating Solar Models with Low Metal Abundances as Good as Those with High Metal Abundances
Wuming Yang
Standard solar models (SSM) constructed in accord with low metal abundances disagree with the seismically inferred results. We constructed rotating solar models with low metal abun…
Ages and Masses of 0.64 million Red Giant Branch stars from the LAMOST Galactic Spectroscopic Survey
Yaqian Wu, Maosheng Xiang, Gang Zhao +13
We present a catalog of stellar age and mass estimates for a sample of 640\,986 red giant branch (RGB) stars of the Galactic disk from the LAMOST Galactic Spectroscopic Survey (DR4…
Frequent flare events on the short-period M-type eclipsing binary BX Tri
ChangQing Luo, XiaoBin. Zhang, Kun Wang +8
We present long-term, multi-color photometric monitoring and spectroscopic observations of the short-period M-type eclipsing binary BX Tri. Six flare events were recorded in 4 year…
Radial velocity measurements from LAMOST medium-resolution spectroscopic observations: A pointing towards the Kepler field
Nian Liu, Jian-Ning Fu, Weikai Zong +20
Radial velocity is one of key measurements in understanding the fundamental properties of stars, stellar clusters and the Galaxy. A plate of stars in the Kepler field were observed…
