Finding pulsars in Short-period binary systems using a novel pruning algorithm
Most pulsars are extremely faint astrophysical sources, necessitating extended observation times to be coherently integrated for a significant detection. In a typical binary pulsar system, the number of potential orbits, periods, and spin-down combinations ranges from 10^25 to 10^35, rendering exhaustive enumeration impractical. Approximations such as uniform acceleration compromise the sensitivity of pulsar searches, leaving a significant portion of the detectable parameter space unexplored. We present a novel pruning algorithm that will significantly improve pulsar detection in short-period binary systems, allowing for observation times longer than an orbital period. Our current implementation of this pruning algorithm systematically evaluates all valid options for circular orbits within small data segments with statistically significant detection for the entire dataset. The computational efficiency gained through the pruning process can be channeled into extending integration times as much as possible, ultimately enhancing our ability to detect faint binary pulsars.
