Superflares, chromospheric activities and photometric variabilities of solar-type stars from the second-year observation of TESS and spectra of LAMOST
Zuo-Lin Tu, Ming Yang, H. -F. Wang +1
In this work, 1272 superflares on 311 stars are collected from 22,539 solar-type stars from the second-year observation of Transiting Exoplanet Survey Satellite (TESS), which almos…
Possible periodic activity in the short bursts of SGR 1806-20: connection to fast radio bursts
G. Q. Zhang, Zuo-Lin Tu, F. Y. Wang
Magnetars are highly magnetized neutron stars that are characterized by recurrent emission of short-duration bursts in soft gamma-rays/hard X-rays. Recently, FRB 200428 were found…
Dispersion and Rotation Measures from the Ejecta of Compact Binary Mergers: Clue to the Progenitors of Fast Radio Bursts
Z. Y. Zhao, G. Q. Zhang, Y. Y. Wang +2
Since the discovery of FRB 200428 associated with the Galactic SGR 1935+2154, magnetars are considered to power fast radio bursts (FRBs). It is widely believed that magnetars could…
Bursts before Burst: A Comparative Study on FRB 200428-associated and FRB-absent X-ray Bursts from SGR J1935+2154
Yu-Han Yang, Bin-Bin Zhang, Lin Lin +8
Accompanied by an X-ray burst, the fast radio burst (FRB) FRB 200428 was recently confirmed as originating from the Galactic magnetar soft gamma repeater (SGR) SGR J1935+2154. Just…
Superflares on solar-type stars from the first year observation of TESS
Zuo-Lin Tu, Ming Yang, Z. J. Zhang +1
Superflares, as strong explosions on stars, have been well studied with the progress of space time-domain astronomy. In this work, we present the study of superflares on solar-type…
Probing cosmic acceleration by strong gravitational lensing systems
Z. L. Tu, J. Hu, F. Y. Wang
Recently, some divergent conclusions about cosmic acceleration were obtained using type Ia supernovae (SNe Ia), with opposite assumptions on the intrinsic luminosity evolution. In…
