An Empirical Sample of Spectra of M-type Stars with Homogeneous Atmospheric-Parameter Labels
Bing Du, A-Li Luo, Song Wang +6
The discrepancies between theoretical and observed spectra, and the systematic differences between various spectroscopic parameter estimates, complicate the determination of atmosp…
Distance and stellar parameter estimations of solar-like stars from the LAMOST spectroscopic survey
Yue-Yue Shen, A-Li Luo
Context. The Gaia mission has opened up a new era for the precise astrometry of stars, thus revolutionizing our understanding of the Milky Way. However, beyond a few kiloparseconds…
M31N 2013-10c: A Newly Identified Recurrent Nova in M31
Allen W. Shafter, Kamil Hornoch, Hana Kučáková +11
The nova M31N 2023-11f (2023yoa) has been recently identified as the second eruption of a previously recognized nova, M31N 2013-10c, establishing the latter object as the 21st recu…
Projected rotational velocities for LAMOST stars with effective temperature lower than 9000 K
Fang Zuo, A-Li Luo, Bing Du +5
In Data Release 9 of LAMOST, we present measurements of v sin i for a total of 121,698 stars measured using the Medium Resolution Spectrograph (MRS) and 80,108 stars using the Low…
Stellar Atmospheric Parameters for Cool Dwarfs in Gaia DR3
Cai-Xia Qu, A-Li Luo, Rui Wang +4
We provide a catalogue of atmospheric parameters for 1,806,921 cool dwarfs from Gaia DR3 which lie within the range covered by LAMOST cool dwarf spectroscopic parameters: 3200 K <…
The HI gas fraction scaling relation of the Green Pea galaxies
Siqi Liu, A-Li Luo, Wei Zhang +3
Green Pea galaxies are compact galaxies with high star formation rates. However, limited samples of Green Pea galaxies have HI 21 cm measurements. Whether the HI gas fraction f_{HI…
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…
A focus on L dwarfs with trigonometric parallaxes
Y. Wang, R. L. Smart, Z. Shao +6
We report new parallax measurements for ten L and early T type dwarfs, five of which have no previous published values, using observations over 3 years at the robotic Liverpool Tel…
The Comparison of Stellar Atomspheric Parameters between LAMOST and APOGEE databases
Y. Q. Chen, G. Zhao, C. Liu +8
We have compared the stellar parameters, temperature, gravity and metallicity, between the LAMOST-DR2 and SDSS-DR12/APOGEE database for stars in common. It is found that the LAMOST…
Metallicity calibration for solar type stars based on red spectra
J. K. Zhao, G. Zhao, Y. Q. Chen +1
Based on high resolution and high signal-to-noise ratio (S/N) spectra analysis of 90 solar type stars, we have established several new metallicity calibrations in Teff range [5600,…
