Determining the Orbits of Pulsars Found Through Jerk Searches on Fermi Sources

Abstract

Using jerk search on targeted observations of unassociated Fermi Gamma-ray sources using Green Bank and Arecibo Telescopes has resulted in the discovery of a dozen new millisecond pulsars (MSPs). We propose to observe six of the MSPs to find their orbital solutions. These orbital solutions will allow a search for gamma-ray pulsations in Fermi-LAT data and help guide future timing observations of these MSPs. Timing these new MSPs is important to study the binary system they're found in and derive important properties such as total energy output, magnetic field strengths, and characteristic ages. These studies will help probe physics at extreme densities. Furthermore, phase-connected timing solutions will make possible multi-wavelength studies of these systems and gauge their suitability as candidates for pulsar timing arrays.
