Convolutional Neural Networks for Searching Superflares from Pixel-level Data of the Transiting Exoplanet Survey Satellite
Zuo-Lin Tu, Qin Wu, Wenbo Wang +3
In this work, six convolutional neural networks (CNNs) have been trained based on %different feature images and arrays from the database including 15,638 superflare candidates on s…
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…
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…
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…
