“…Hewish et al (1968) demonstrated that the period of the first pulsar, B1919+21, was stable to one part in 10 7 over a time-scale of a few months. Following the discovery of the millisecond pulsar, B1937+21, in 1982 (Backer et al 1982) it was demonstrated that its period could be measured to one part in 10 13 or better (Davis et al 1985). This unrivaled stability leads to a host of applications including time keeping, probes of relativistic gravity and natural gravitational wave detectors.…”

“…(2) The original millisecond pulsar, B1937+21, discovered by Backer et al (1982) has a period of only 1.5578 ms. The implied spin frequency of 642 Hz means that this neutron star is close to being torn apart by centrifugal forces.…”

“…Contrary to the other two selected targets, PSR J1939+2134 (also known as PSR B1937+21) is an isolated MSP, the first detected ever (Backer et al 1982) and ranked as the most rapidly rotating pulsar until 2006 (Hessels et al 2006). The positional and rotational parameters of the source at the time of the AURIGA runs resulted from timing observations conducted at the Jodrell Bank Observatory with the same instrumental set up as for PSR J0218+4232.…”

Aims. We report on a search for continuous gravitational wave emission from three recycled radio pulsars, performed by using the data of the resonant detector AURIGA. Given the spin rate of the selected targets -the isolated pulsar PSR J1939+2134 and the binary pulsars PSR J0024-7204J and PSR J0218+4232 -the expected frequency of the emitted gravitational waves falls in the high sensitivity range of the detector. Methods. The main topic is the method, meaning that the statistical analysis is performed by implementing a slightly modified version of the Feldman and Cousins Unified Approach. Results. By using ephemerides provided by suitable radio observations of the targets, we were able to demodulate the Doppler shifts within a coherence time of 1 day, and then incoherently sum 10 daily spectra collected from December 8th to December 17th, 2006. We have found upper limits on the gravitational wave amplitudes in the order of a few units of 10 −23 at 90% Confidence Level (C.L.), which translate to limits in the ellipticity of the targeted pulsars of ε < 10 −4 at 90% C.L. Conclusions. The same framework can then be applied to data coming from most sensitive experiments as VIRGO or LIGO; moreover, an application to recently discovered transients in X-ray pulsars is discussed.
