We present results from timing observations of 27 pulsars made at the Pushchino Observatory over 33.5 yr between 1978 July and 2012 February. We also analyze archival Jet Propulsion Laboratory data of 10 pulsars to extend individual data span to 43.5

Nature of cyclical changes in the timing residuals from the pulsar B1642-03

Autor: Shabanova, T. V.

Publikováno v: Astrophys.J.700:1009-1016,2009

We report an analysis of timing data for the pulsar B1642-03 (J1645-0317) gathered over the 40-year time span between 1969 and 2008. During this interval, the pulsar experienced eight glitch-like events with a fractional increase in the rotation freq

Evolution of the inclination angle of radio pulsars is observable effect

Autor: Istomin, Y. N., Shabanova, T. V.

It is shown that the slow glitches in the spin rate of the pulsar B1822-09 can be explained by the reconstruction of the neutron star shape, which is not matched with the star rotation axis. Owing to the evolution of the inclination angle, i.e. the a

Observations of three slow glitches in the spin rate of the pulsar B1822-09

Autor: Shabanova, T. V.

Publikováno v: Mon.Not.Roy.Astron.Soc. 356 (2005) 1435-1439

Three slow glitches in the rotation rate of the pulsar B1822-09 were revealed over the 1995-2004 interval. The slow glitches observed are characterized by a gradual increase in the rotation frequency with a long timescale of several months, accompani

Properties of the linearly polarized radiation from PSR B0950+08

Autor: Shabanova, T. V., Shitov, Yu. P.

Publikováno v: Astron.Astrophys. 418 (2004) 203

Measurements of average pulse profiles made with a single linear polarization over the range 41-112 MHz are presented for PSR B0950+08. We show that the observed variable structure of the pulse profiles is a result of Faraday sinusoidal modulation of

Evidence for Free Precession in the Pulsar B1642-03

Autor: Shabanova, T. V., Lyne, A. G., Urama, J. O.

We present an analysis of the timing data of the pulsar B1642-03, collected over a span of 30 years between 1969 and 1999. During this interval, the timing residuals exhibit cyclical changes with amplitude varying from 15 ms to 80 ms and spacing of m
