The braking index of PSR B0540−69 and the associated pulsar wind nebula emission after spin-down rate transition
Libin Wang,Ming-Yu Ge,J. S. Wang,Shan-Shan Weng,Hao Tong,L. L. Yan,S. N. Zhang,Zi-Gao Dai,Li-Ming Song +8 more
TL;DR: In this paper, the authors found that most of the current models have difficulties in explaining the measured braking index and suggested that the field increase may result from some instabilities within the pulsar core that enhance the poloidal component at the price of toroidal component of the magnetic field.

Revisiting the confrontation of the shock-powered synchrotron maser model with the Galactic FRB 200428
TL;DR: In this paper, the authors investigated the possibility that the fast radio burst (FRB 200428) from the Galactic magnetar SGR 1935+2154 robustly indicated that FRB phenomena can sometimes be produced by magnetars, although it is uncertain whether the cosmological FRBs can share the same origin with this Galactic event.
Journal ArticleDOI
Kilonova Emission from Black Hole–Neutron Star Mergers: Observational Signatures of Anisotropic Mass Ejection
TL;DR: In this paper, anisotropic ejecta in binary neutron star (BH-NS) mergers was investigated and a bump appeared on the luminosity light curve due to the inhomogeneous mass distribution in the latitudinal direction.
Journal ArticleDOI
An Accreting Stellar Binary Model for Active Periodic Fast Radio Bursts
TL;DR: In this paper, an accreting stellar binary model was proposed to understand the active periodic Fast radio bursts (FRBs), where the system consists of a stellar compact object and a donor star (DS) companion in an eccentric orbit, where the DS filled its own Roche lobe near the periastron.
Journal ArticleDOI
The Energy Sources of Double-peaked Superluminous Supernova PS1-12cil and Luminous Supernova SN 2012aa
TL;DR: In this paper, the authors present the study for the energy reservoir powering the light curves (LCs) of PS1-12cil and SN 2012aa which are superluminous and luminous supernovae (SNe), respectively.
