Title: Competing Drifting Radio Subpulses in Psr B0031−07 Competing Drifting Radio Subpulses in Psr B0031−07
The pair of drifting subpulses of the radio pulsar PSR B0031−07 appear to be well separated from each other on the average, overlapping at less than one thirtieth of the peak energy. Strictly, the integrated profile of the pair (after removing the drift) does not show more than two subpulses; however this result is likely to be modified with the availability of more data. On the other hand, rar...
متن کاملGiant pulses in Pulsar PSR B 0031 – 07
We report on observations of the recently detected (Kuzmin et al. 2004) giant pulses (GPs) from the pulsar PSR B0031–07 at 40 and 111 MHz. At 40 MHz the peak flux density of the strongest pulse is 1 100 Jy, which is 400 times as high as the peak flux density of the average pulse (AP). A pulse whose observed peak flux exceeded the peak of the AP by more than a factor of 200 is encountered approx...
متن کاملDetection of Giant Pulses in pulsar PSR J 1752 + 2359
We report the detection of Giant Pulses (GPs) in the pulsar PSR J1752+2359. About one pulse in 270 has a peak flux density more than 40 times the peak flux density of an average pulse (AP), and the strongest GP is as large as 260. The energy of the strongest GP exceeds the energy of the average pulse by a factor of 200 which is greater than in other known pulsars with GPs. PSR J1752+2359 as wel...
متن کاملFrequency dependence of the drifting subpulses of PSR B 0031 − 07
The well known drifter PSR B0031−07 is known to exhibit drifting subpulses where the spacing between the drift bands (P 3) shows three distinct modes A, B and C corresponding to 12, 6 and 4 seconds respectively. We have investigated pe-riodicities and polarisation properties of PSR B0031−07 for a sequence of 2700 single pulses taken simultaneously at 328 MHz and 4.85 GHz. We found that mode A o...
متن کاملDetermination of the geometry of the PSR B1913+16 system by geodetic precession
New observations of the binary pulsar B1913+16 are presented. Since 1978 the leading component of the pulse profile has weakend dramatically by about 40%. For the first time, a decrease in component separation is observed, consistent with expectations of geodetic precession. Assuming the correctness of general relativity and a circular hollow-cone like beam, a fully consistent model for the sys...
