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…
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…
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…
