High-redshift GRB 140304A at z = 5.282 with flaring activity: A multi-wavelength study
Shashi. B. Pandey, Amit. K. Ror, A. J. Castro-Tirado +48
Context. This article presents a detailed multi-wavelength analysis of GRB 140304A at z = 5.282, having uncommon late-time flaring features. The aim is to study GRB 140304A and oth…
White-light superflare and long-term activity of the nearby M7 type binary EI~Cnc observed with GWAC system
Hua-Li Li, Jing Wang, Li-Ping Xin +14
Stellar white-light flares are believed to play an essential role on the physical and chemical properties of the atmosphere of the surrounding exoplanets. Here we report an optical…
Photometric observations of flares on AD Leo from GWAC-F30 and TESS
Jian-Ying Bai, Jing Wang, Hua-Li Li +4
We observed active M dwarf star AD Leo for 146 hr in photometry by GWAC-F30 and also analyzed 528-hr photometric data of the star from TESS. A total of 9 and 70 flares are detected…
A huge-amplitude white-light superflare on a L0 brown dwarf discovered by GWAC survey
Li-Ping Xin, Hua-li Li, Jing Wang +21
White-light superflares from ultra cool stars are thought to be resulted from magnetic reconnection, but the magnetic dynamics in a fully convective star is not clear yet. In this…
Magnetic activities and parameters of 43 flare stars in the GWAC archive
Guang-Wei Li, Chao Wu, Gui-Ping Zhou +19
In the archive of the Ground Wide Angle Camera (GWAC), we found 43 white light flares from 43 stars, among which, three are sympathetic or homologous flares, and one of them also h…
Accretion and Host-Galaxy Properties of 14 New "Changing-Look'' Active Galactic Nuclei Identified from the SDSS-V Survey
J. Wang, D. W. Xu, J. Y. Bai +4
The widely accepted active galactic nucleus (AGN) paradigm has been recently challenged by the discovery of the so-called ``changing-look'' (CL) phenomenon characterized by spectra…
Flaring-associated Complex Dynamics in Two M-dwarfs Revealed by Fast, Time-resolved Spectroscopy
J. Wang, H. L. Li, L. P. Xin +11
Habitability of an exoplanet is believed to be profoundly affected by activities of the host stars, although the related coronal mass ejections (CMEs) are still rarely detected in…
Investigating Variable Stars in the Open Cluster NGC 1912 and Its Surrounding Field
Chunyan Li, Ali Esamdin, Yu Zhang +6
In this work, we studied the variable stars in the open cluster NGC 1912 based on the photometric observations and DR2 data. More than 3600 CCD frames in B, V, R filters wer…
Photometric and Spectroscopic Study of Flares on Ross 15
Jian-Ying Bai, Ali Esamdin, Xing Gao +2
We conducted photometric and spectroscopic observations for Ross 15 in order to further study the flare properties of this less observed flare star. A total of 28 B-band flares are…
