Discovery of Nine Super Li-rich Unevolved Stars from the LAMOST Survey
T. -S. Yan, J. -R. Shi, L. Wang +7
Based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) medium-resolution spectroscopic survey (MRS), we report the discovery of nine super Li-rich unevolve…
Exploring Lorentz Invariance Violation from Ultra-high-energy Gamma Rays Observed by LHAASO
Zhen Cao, F. Aharonian, Q. An +268
Recently the LHAASO Collaboration published the detection of 12 ultra-high-energy gamma-ray sources above 100 TeV, with the highest energy photon reaching 1.4 PeV. The first detect…
Extended Very-High-Energy Gamma-Ray Emission Surrounding PSR J0622 + 3749 Observed by LHAASO-KM2A
The LHAASO collabration, Zhen Cao, F. Aharonian +310
We report the discovery of an extended very-high-energy (VHE) gamma-ray source around the location of the middle-aged (207.8 kyr) pulsar PSR J0622+3749 with the Large High Altitude…
The white dwarf binary pathways survey V. The Gaia white dwarf plus AFGK binary sample and the identification of 23 close binaries
J. -J. Ren, R. Raddi, A. Rebassa-Mansergas +22
Close white dwarf binaries consisting of a white dwarf and an A, F, G or K type main sequence star, henceforth close WD+AFGK binaries, are ideal systems to understand the nature of…
LEMONY--a Library of Empirical Medium-resolution spectra by Observations with the NAOC Xinglong 2.16\,m and YNAO Gaomeigu 2.4\,m telescopes
Chun Wang, Xiaowei Liu, Yang Huang +15
This study expands the coverage and improves the homogeneity of the distribution of MILES template stars in the parameter space, as well as extends the wavelength coverage of the t…
Chemical abundances of primary stars in the Sirius-like binary systems
X. M. Kong, G. Zhao, J. K. Zhao +6
Study of primary stars lying in Sirius-like systems with various masses of WD companions and orbital separations is one of the key aspects to understand the origin and nature of Ba…
Systematic non-LTE study of the [Fe/H] F and G dwarfs in the solar neighbourhood. II. Abundance patterns from Li to Eu
G. Zhao, L. Mashonkina, H. L. Yan +14
For the first time, we present an extensive study of stars with individual non-local thermodynamic equilibrium (NLTE) abundances for 17 chemical elements from Li to Eu in a sample…
Activity indicators and stellar parameters of the Kepler targets. An application of the ROTFIT pipeline to LAMOST-Kepler stellar spectra
A. Frasca, J. Molenda-Zakowicz, P. De Cat +7
The LAMOST-Kepler survey, whose spectra are analyzed in the present paper, is the first large spectroscopic project aimed at characterizing these sources. Our work is focused at se…
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope Quasar Survey: Quasar Properties from First Data Release
Y. L. Ai, Xue-Bing Wu, Jinyi Yang +20
We present preliminary results of the quasar survey in Large Sky Area Multi- Object Fiber Spectroscopic Telescope (LAMOST) first data release (DR1), which includes pilot survey and…
LAMOST observations in the Kepler field. Database of low-resolution spectra
P. De Cat, J. N. Fu, A. B. Ren +34
The nearly continuous light curves with micromagnitude precision provided by the space mission Kepler are revolutionising our view of pulsating stars. They have revealed a vast sea…
Systematic NLTE study of the -2.6 < [Fe/H] < 0.2 F and G dwarfs in the solar neighbourhood. I. Stellar atmosphere parameters
T. Sitnova, G. Zhao, L. Mashonkina +9
We present atmospheric parameters for 51 nearby FG dwarfs uniformly distributed over the -2.60 < [Fe/H] < +0.20 metallicity range that is suitable for the Galactic chemical evoluti…
Possible discovery of the r-process characteristics in the abundances of metal-rich barium stars
W. Y. Cui, B. Zhang, J. R. Shi +3
We study the abundance distributions of a sample of metal-rich barium stars provided by Pereira et al. (2011) to investigate the s- and r-process nucleosynthesis in the metal-rich…
Chromospheric variabilities of M active stars based on Guoshoujing Telescope
Q. F. Pi, L. Y. Zhang, J. R. Shi +7
For the M active catalogue of Guoshoujing Telescope (LAMOST), 933 sources are presented in at least two exposures. We found that many M active stars show chromospheric variabilitie…
