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…
Quasar 2175 Å dust absorbers I: metallicity, depletion pattern, and kinematics
Jingzhe Ma, Jian Ge, Yinan Zhao +4
We present 13 new 2175 Å dust absorbers at z_abs = 1.0 - 2.2 towards background quasars from the Sloan Digital Sky Survey. These absorbers are examined in detail using data from th…
Reddening and He I* Absorption Lines in Three Narrow-line Seyfert 1 Galaxies
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +6
We report the detection of heavy reddening and the He I* absorption lines at the AGNs' redshift in three Narrow-line Seyfert 1 galaxies: SDSS J091848.61+211717.0, SD…
Photoionization-driven Absorption Lines Variability in Balmer Absorption Line Quasar LBQS 1206+1052
Luming Sun, Hongyan Zhou, Tuo Ji +10
In this paper we present an analysis of absorption line variability in mini-BAL quasar LBQS 1206+1052. The SDSS spectrum demonstrates that the absorption troughs can be divided int…
