The Xuyi Schmidt Telescope Photometric Survey of the Galactic Anti-center (XSTPS-GAC) is a photometric sky survey that covers nearly 6 000 deg^2 towards Galactic anti-center in g r…
Enormous Li-enhancement preceding red giant phases in low-mass stars in the Milky Way halo
Haining Li, Wako Aoki, Tadafumi Matsuno +4
Li abundances in the bulk of low-mass metal-poor stars are well reproduced by stellar evolution models adopting a constant initial abundance. However, a small number of stars have…

Yaqian Wu, Maosheng Xiang, Shaolan Bi +13
Obtaining accurate and precise masses and ages for large numbers of giant stars is of great importance for unraveling the assemblage history of the Galaxy. In this paper, we estima…
Herschel and SCUBA-2 observations of dust emission in a sample of Planck cold clumps
Mika Juvela, Jinhua He, Katherine Pattle +26
Analysis of all-sky Planck submillimetre observations and the IRAS 100um data has led to the detection of a population of Galactic cold clumps. The clumps can be used to study star…
Evolution of Relative Magnetic Helicity: New Boundary Conditions for the Vector Potential
Shangbin Yang, Joerg Buechner, Jan Skala +1
We recently proposed a method to calculate the relative magnetic helicity in a finite volume for a given magnetic field which however required the flux to be balanced separately on…
Different ways to estimate graviton mass
Alexander F. Zakharov, Predrag Jovanovic, Dusko Borka +1
An experimental detection of graviton is extremely hard problem, however, there are different ways to evaluate a graviton mass if it is non-vanishing. Theories of massive gravity o…
Flux and Spectral Variation Characteristics of 3C 454.3 at the GeV Band
Hai-Ming Zhang, Jin Zhang, Rui-Jing Lu +3
We analyze the long-term lightcurve of 3C 454.3 observed with Fermi/LAT and investigate its relation to the flux in the radio, optical, and X-ray bands. By fitting the 1-day binned…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Baryon Acoustic Oscillations at redshift of 0.72 with the DR14 Luminous Red Galaxy Sample
Julian E. Bautista, Mariana Vargas-Magaña, Kyle S. Dawson +16
The extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 14 sample includes 80,118 Luminous Red Galaxies. By combining these galaxies with the high-redshift tail o…
Imaging the Molecular Outflows of the Prototypical ULIRG NGC 6240 with ALMA
T. Saito, D. Iono, J. Ueda +12
We present 0".97 0".53 (470 pc 250 pc) resolution CO ( = 2-1) observations toward the nearby luminous merging galaxy NGC 6240 with the Atacama Large Millimeter…
Proper motion of the radio pulsar B1727-47 and its association with the supernova remnant RCW 114
P. Shternin, M. Yu, A. Kirichenko +4
We report preliminary results of the analysis of the proper motion of the bright radio pulsar B172747. Using archival Parkes timing data, as well as original and archival ATCA i…
GPU-Based High-Performance Imaging for Mingantu Spectral RadioHeliograph
Ying Mei, Feng Wang, Wei Wang +6
As a dedicated solar radio interferometer, the MingantU SpEctral RadioHeliograph (MUSER) generates massive observational data in the frequency range of 400 MHz -- 15 GHz. High-perf…
The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
Transiting Exoplanet Monitoring Project (TEMP). III. On the Relocation of the Kepler-9~b Transit
Songhu Wang, Dong-Hong Wu, Brett C. Addison +24
The Kepler-9 system harbors three known transiting planets. The system holds significant interest for several reasons. First, the outer two planets exhibit a period ratio that is c…
The Near-infrared Optimal Distances Method Applied to Galactic Classical Cepheids Tightly Constrains Mid-infrared Period--Luminosity Relations
Shu Wang, Xiaodian Chen, Richard de Grijs +1
Classical Cepheids are well-known and widely used distance indicators. As distance and extinction are usually degenerate, it is important to develop suitable methods to robustly an…
Searching for the Transit of the Earth--mass exoplanet Proxima~Centauri~b in Antarctica: Preliminary Result
Hui-Gen Liu, Peng Jiang, Xingxing Huang +21
Proxima Centauri is known as the closest star from the Sun. Recently, radial velocity observations revealed the existence of an Earth-mass planet around it. With an orbital period…
