Nulling Phenomenon of the New Radio Pulsar J0810+37 at a Frequency of 111 MHz.

Pulsar J0810+37 with a period of 1.2483 s is detected at a frequency of 111 MHz during the pulsar search at the Big Scanning Antenna (BSA) radio telescope of the Lebedev Physical Institute [1]. In this paper, we present the results of the detailed study of radio emission from J0810+37 which exhibits a rare nulling effect of different durations in a very wide time interval with an average nulling fraction in "switch-on" days 〈NF〉 = 38%; considering "switch-off" days, 〈NF〉 = 74%, since radio emission from this source is interrupted on average by 2–3 days, and then it again revives on average for 1–2 days. The "switch-off" periods reach 7 days. [ABSTRACT FROM AUTHOR]
