Remarks: SRT will observe J1023 on the nights of March 7/8 and 8/9, from 20.00 UT to 2.00 UT. The source is visible with NICER in these time windows for ~13 ks. This exposure also appears to be optimal to perform accurate searches on the time of passage at the ascending node, pivotal to search for radio pulsations.
ToO: Y
Coordinate Observation: Y
Observatory: SARDINIA RADIO TELESCOPE
Description: We want to search radio pulses from J1023 with SRT in the C-low band. X-ray/optical pulses seem to be due to the shock between the pulsar wind and the inner accretion disk. If this scenario holds true, radio pulsations are probably generated by the same mechanism. Pulsars are usually observed at 1.5 GHz. Due to the presence of matter surrounding the NS, we want to observe at higher frequencies.
