A Quasi-periodic propagating wave and EUV waves excited simultaneously in a solar eruption event
Y. H. Miao, Y. Liu, Y. D. Shen +4
Quasi-periodic fast-propagating (QFP) magnetosonic waves and extreme ultraviolet (EUV) waves were proposed to be driven by solar flares and coronal mass ejections (CMEs), respectiv…
Photometric Investigation of the Contact Binary GU Ori with High Metallicity
Xiao Zhou, Shengbang Qian, Boonrucksar Soonthornthum +5
GU Ori was observed with the 1m telescope at Yunnan Observatories in 2005. To determine its physical properties, the Wilson-Devinney program is used. The results reveal that GU Ori…
The initial morphologies of the wavefronts of extreme ultraviolet waves
Ruisheng Zheng, Zhike Xue, Yao Chen +2
The morphologies of the wavefronts of extreme ultraviolet (EUV) waves can shed light on their physical nature and driving mechanism that are still strongly debated. In reality, the…
Untwisting and Disintegration of a Solar Filament Associated with Photospheric Flux Cancellation
Huadong Chen, Ruisheng Zheng, Leping Li +3
Using the high-resolution observations from New Vacuum Solar Telescope (NVST) jointly with the Solar Dynamics Observatory data, we investigate two successive confined eruptions (Er…
The double blue straggler sequence in NGC 2173: a field contamination artefact?
Chengyuan Li, Licai Deng, Richard de Grijs +2
Li et al. (2018) (hereafter L18) detected two apparently distinct populations of blue straggler stars (BSSs) in the young globular cluster NGC 2173, a similar feature as observed i…
Dense matter with eXTP
Anna L. Watts, Wenfei Yu, Juri Poutanen +73
In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores host an extr…
Observations of SN 2017ein Reveal Shock Breakout Emission and A Massive Progenitor Star for a Type Ic Supernova
Danfeng Xiang, Xiaofeng Wang, Jun Mo +23
We present optical and ultraviolet observations of nearby type Ic supernova SN 2017ein as well as detailed analysis of its progenitor properties from both the early-time observatio…
Formation of Extremely Low-mass White Dwarfs in Double Degenerates
Zhenwei Li, Xuefei Chen, Hai-Liang Chen +1
Extremely low-mass white dwarfs (ELM WDs) are helium WDs with a mass less than . Most ELM WDs are found in double degenerates (DDs) in the ELM Survey led by…
Optical and radio transients after the collapse of super-Chandrasekhar white dwarf merger remnants
Yun-Wei Yu, Aming Chen, Bo Wang
Super-Chandrasekhar remnants of double white dwarf mergers could sometimes collapse into a rapidly rotating neutron star (NS), accompanying with a mass ejection of a few times $0.0…
Reddening of the BLR and NLR in AGN From a Systematic Analysis of Balmer Decrement
Kai-Xing Lu, Yinghe Zhao, Jin-Ming Bai +1
We selected an active galactic nuclei (AGN) sample () from Sloan Digital Sky Survey Data Release 7, and measured the broad- () and narrow-line…
Subdwarf B stars as possible surviving companions in Type Ia supernova remnants
Xiangcun Meng, Jiao Li
Although type Ia supernovae (SNe Ia) are so important in many astrophysical fields, a debate on their progenitor model is still endless. Searching the surviving companion in a supe…
K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova
G. Dimitriadis, R. J. Foley, A. Rest +145
We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
The outcomes of carbon-oxygen white dwarfs accreting CO-rich material
Chengyuan Wu, Bo Wang, Dongdong Liu
The double-degenerate model, involving the merger of double carbon-oxygen white dwarfs (CO WDs), is one of the two classic models for the progenitors of type Ia supernovae (SNe Ia)…
Past and future of the central double-degenerate core of Henize 2-428
Donghao Wu, Dongdong Liu, Bo Wang
It has been suggested that SNe Ia could be produced in the condition of the violent merger scenario of the double-degenerate model, in which a thermonuclear explosion could be prod…
DE CVn: an eclipsing post-common envelope binary with a circumbinary disk and a giant planet
Z. T Han, S. B. Qian, L. Y. Zhu +8
We present a timing analysis of the eclipsing post-common envelope binary (PCEB) DE CVn. Based on new CCD photometric observations and the published data, we found that the orbital…
Subarcsecond blobs in flare-related coronal jets
Q. M. Zhang, L. Ni
In this paper, we report our multiwavelength observations of subarcsecond blobs in coronal jets. In AR 12149, a C5.5 circular-ribbon flare occurred on 2014 August 24. Two jets (jet…
