A pulsar escaping an ancient open cluster via tidal stripping
Lei Zhang, Xiaoting Fu, Di Li +21
Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…
Pulsed radio emission from a Central Compact Object
Lei Zhang, Alessandro Ridolfi, Di Li +7
Located at the centres of supernova remnants, central compact objects (CCOs) are among the most puzzling neutron stars. CCOs are bright in thermal X-rays, yet have evaded detection…
On Ultra-long Period (53.8 min) Pulsar ASKAP J1935+2148: Coherent Radio Emission Triggered by Local Superstrong Magnetic Reconnection
Zhi-Yao Yang, Cheng-Min Zhang, De-Hua Wang +5
The eight ultra-long period pulsars (ULPPs) in radio bands have been discovered recently, e.g., ASKAP J1935+2148 with a spin period of 53.8\,min, which are much longer than those o…
Sensitive Constraints on Coherent Radio Emission from Five Isolated White Dwarfs
Lei Zhang, Alexander Wolszczan, Joshua Pritchard +8
Coherent, periodic radio emission from pulsars has been widely interpreted as evidence of neutron stars as strongly magnetized compact objects. In recent years, radio pulses have a…
