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 کاملThe Polarization of Drifting Subpulses
Using new techniques based on the polarimetric fluctuation spectrum, the fluctuation behaviour of the polarization of individual pulses is examined in three pulsars that show drifting subpulses, allowing various aspects of the fluctuations to be quantified for the first time. Of the three pulsars studied, only PSR B0809+74 shows behaviour completely consistent with the superposition of orthogon...
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 کاملOn the origin of the drifting subpulses in radio pulsars
A model for the main observational characteristics of the radio emission of pulsars with well organized drifting subpulses is presented. We propose that drifting subpulses result from the modulation of the radio emission mechanism due to long-wavelength drift waves in the magnetosphere. The drift waves are generated at shorter wavelengths, and their nonlinear evolution favours accumulation in a...
متن کاملS2DFS: analysis of temporal changes of drifting subpulses
Context. We introduce a new technique, called the sliding two-dimensional fluctuation spectrum, used for detecting and characterising the temporal changes of drifting subpulses from radio pulsars. The method was tested using simulated data as well as archived observations made with the Westerbork Synthesis Radio Telescope (WSRT) at wavelengths of 92 and 21 cm. Aims. The drifting subpulse phenom...
