Constraints on single-degenerate Chandrasekhar mass progenitors of Type Iax supernovae
Zheng-Wei Liu, Takashi J. Moriya, Richard J. Stancliffe +1
SNe Iax are proposed as one new sub-class of SNe Ia. SNe Iax have been estimated to account for ~5-30% of the total SN Ia rate, and most SNe Iax have been discovered in late-type g…

Using the high tempo-spatial resolution H images observed with the New Vacuum Solar Telescope, we report the solid observational evidence of magnetic reconnection between two se…
Revisiting Correlations Between Broad-Line and Jet Emission Variations for AGNs: 3C 120 and 3C 273
H. T. Liu, J. M. Bai, H. C. Feng +1
We restudy the issue of cross-correlations between broad-line and jet emission variations, and aim to locate the position of radio (and gamma-ray) emitting region in jet of active…
Doppler images of the eclipsing binary ER Vulpeculae
Yue Xiang, Shenghong Gu, A. Collier Cameron +1
We present Doppler images of both components of the eclipsing binary system ER Vul, based on the spectra obtained in 2004 November, 2006 September and 2008 November. The least-squa…
AstroCloud, a Cyber-Infrastructure for Astronomy Research: Data Archiving and Quality Control

The THU-NAOC Transient Survey: the Performance and the First-year Result
Tianmeng Zhang, Xiaofeng Wang, Junchen Chen +18
The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs),…
A pair of CO + He white dwarfs as the progenitor of 2005E-like supernovae?
Xiangcun Meng, Zhanwen Han
Ca-rich transients (CRTs, 2005E-like supernovae) exhibit unusually strong Ca features during their nebular phase, and their distribution in their host galaxies indicates that they…
Radiation fields by intermediate-age stellar populations with binaries as ionizing sources of H II regions
F. Zhang, L. Li, L. Cheng +4
Radiation fields emitted by O, B-type stars or young stellar populations (SPs) are generally considered as significant central ionizing sources (CISs) of classic H II regions. In o…
SDSS J013127.34032100.1: A newly discovered radio-loud quasar at with extremely high luminosity
Wei-Min Yi, Feige Wang, Xue-Bing Wu +18
Only very few z>5 quasars discovered to date are radio-loud, with a radio-to-optical flux ratio (radio-loudness parameter) higher than 10. Here we report the discovery of an optica…
Unwinding motion of a twisted active-region filament
X. L. Yan, Z. K. Xue, J. H. Liu +2
To better understand the structures of active-region filaments and the eruption process, we study an active-region filament eruption in active region NOAA 11082 in detail on June 2…
Searching for variable stars in the cores of five metal rich globular clusters using EMCCD observations
Jesper Skottfelt, D. M. Bramich, R. Figuera Jaimes +31
In this paper, we present the analysis of time-series observations from 2013 and 2014 of five metal rich ([Fe/H] -1) globular clusters: NGC~6388, NGC~6441, NGC~6528, NGC~6638,…
The structure of TeV-bright shell-type supernova remnants
Chuyuan Yang, Siming Liu, Jun Fang +1
Aims. Two-dimensional MHD simulations are used to model the emission properties of TeV-bright shell-type supernova remnants (SNRs) and to explore their nature. Methods. In the lept…
The hybrid CONe WD + He star scenario for the progenitors of type Ia supernovae
Bo Wang, Xiangcun Meng, Dongdong Liu +2
The hybrid CONe white dwarfs (WDs) have been suggested to be possible progenitors of type Ia supernovae (SNe Ia). In this article, we systematically studied the hybrid CONe WD + He…
A ring system detected around the Centaur (10199) Chariklo
F. Braga-Ribas, B. Sicardy, J. L. Ortiz +61
Until now, rings have been detected in the Solar System exclusively around the four giant planets. Here we report the discovery of the first minor-body ring system around the Centa…
