D. Mcconnell et al., OBSERVATIONS OF THE MILLISECOND PULSAR J0437-4715 AT 76 MHZ, Monthly Notices of the Royal Astronomical Society, 280(1), 1996, pp. 331-334
We report observations of the millisecond pulsar J0437-4715 at 76 and
90 MHz. These observations give a five-fold increase in the frequency
range of measurements of this pulsar and provide the first record of t
he pulsed emission from any millisecond pulsar below 100 MHz. We find
that the radio spectrum of the mean pulsed emission of J0437-4715 is s
imilar to that of many other pulsars with a spectral turnover between
90 and 400 MHz. J0437-4715 differs from most other pulsars with respec
t to the variation of pulse width with radiation frequency and the rel
ative spectra of pulse components.
