Periodic Activities of Fast Radio Burst Repeaters from Precessing Magnetars with Evolving Obliquity
Xin-Ming Feng, Yuan-Pei Yang, Qiao-Chu Li
Fast radio bursts (FRBs) are cosmological radio transients with millisecond durations and extremely high brightness temperatures. One FRB repeater, FRB 180916.J0158+65 (FRB 180916B…
Polarization Evolution of Fast Radio Burst Sources in Binary Systems
Zhao-Yang Xia, Yuan-Pei Yang, Qiao-Chu Li +3
Recently, some fast radio bursts (FRBs) have been reported to exhibit complex and diverse variations in Faraday rotation measurements (RM) and polarization, suggesting that dynamic…
Spectral Features of the Solar Transition Region and Chromospheric Lines at Flare Ribbons Observed with IRIS
Lingfang Wang, Ying Li, Qiao Li +2
We report on the spectral features of the Si IV 1402.77 Å, C II 1334.53 Å, and Mg II h or k lines, formed in the layers from the transition region to the chromosphere, in three two…
Spectral Observations and Modeling of a Solar White-light Flare Observed by CHASE
De-Chao Song, Jun Tian, Y. Li +11
The heating mechanisms of solar white-light flares remain unclear. We present an X1.0 white-light flare on 2022 October 2 (SOL2022-10-02T20:25) observed by the Chinese \ha\ Solar E…
Transverse vertical oscillations during the contraction and expansion of coronal loops
Qingmin Zhang, Yuhao Zhou, Chuan Li +5
In this paper, we carry out a detailed analysis of the M1.6 class eruptive flare occurring in NOAA active region 13078 on 2022 August 19. The flare is associated with a fast corona…
A giant glitch from the magnetar SGR J1935+2154 before FRB 200428
Mingyu Ge, Yuan-Pei Yang, Fangjun Lu +11
Fast radio bursts (FRBs) are short pulses observed in radio frequencies usually originating from cosmological distances. The discovery of FRB 200428 and its X-ray counterpart from…
Repeating Fast Radio Bursts with High Burst Rates by Plate Collisions in Neutron Star Crusts
Qiao-Chu Li, Yuan-Pei Yang, F. Y. Wang +2
Some repeating fast radio burst (FRB) sources show high burst rates, and the physical origin is still unknown. Outstandingly, the first repeater FRB 121102 appears extremely high b…
AT2020hur: A Possible Optical Counterpart of FRB 180916B
Long Li, Qiao-Chu Li, Shu-Qing Zhong +4
The physical origin of fast radio bursts (FRBs) remains unclear. Finding multiwavelength counterparts of FRBs can be a breakthrough in understanding their nature. In this work, we…
Are there magnetars in high-mass X-ray binaries?
Kun Xu, Xiang-Dong Li, Zhe Cui +4
Magnetars form a special population of neutron stars with strong magnetic fields and long spin periods. About 30 magnetars and magnetar candidates known currently are probably isol…
Periodic Activities of Repeating Fast Radio Bursts from Be/X-ray Binary Systems
Qiao-Chu Li, Yuan-Pei Yang, F. Y. Wang +4
The frequency-dependent periodic active window of the fast radio burst FRB 180916.J0158+65 (FRB 180916B) was observed recently. In this Letter, we propose that a Be/X-ray binary (B…
Do the periodic activities of repeating fast radio bursts represent the spins of neutron stars?
Kun Xu, Qiao-Chu Li, Yuan-Pei Yang +3
Fast radio bursts (FRBs) are mysterious radio transients with millisecond durations. Recently, a periodic activity of 16 day and a possible periodicity of 159 day were…
Persistent Radio Emission from Synchrotron Heating by a Repeating Fast Radio Burst Source in a Nebula
Qiao-Chu Li, Yuan-Pei Yang, Zi-Gao Dai
The first repeating fast radio burst (FRB), FRB 121102, was found to be associated with a spatially coincident, persistent nonthermal radio source, but the origin of the persistent…
Are persistent emission luminosity and rotation measure of fast radio bursts related?
Yuan-Pei Yang, Qiao-Chu Li, Bing Zhang
The physical origin of fast radio bursts (FRBs) is still unknown. Multiwavelength and polarization observations of an FRB source would be helpful to diagnose its progenitor and env…
