Study on the eclipse and noise characteristics of the millisecond pulsar J2055+3829

Spider pulsars are a special class of millisecond pulsars whose radio emission is typically eclipsed by material from their companion stars. Observational studies of these systems are crucial for understanding the evolution of millisecond pulsars and high-precision pulsar timing. In this paper, we present observations of the spider pulsar PSR J2055+3829 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We detect significant pulse scattering during the eclipse, with a maximum scattering timescale reaching 0.4 ms. Furthermore, our noise analysis shows that the timing noise of this pulsar is dominated by pulse jitter on short timescales.
