The Green Bank North Celestial Cap (GBNCC) survey is a 350-MHz all-sky survey
for pulsars and fast radio transients using the Robert C. Byrd Green Bank
Telescope. To date, the survey has discovered over 190 pulsars, including 33
millisecond pulsars (MSPs) and 24 rotating radio transients(RRATs). Several
exotic pulsars have been discovered in the survey, including PSR J1759+5036, a
binary pulsar with a 176-ms spin period in an orbit with a period of 2.04 days,
an eccentricity of 0.3,and a projected semi-major axis of 6.8 light seconds.
Using seven years of timing data, we are able to measure one post-Keplerian
parameter, advance of periastron, which has allowed us to constrain the total
system mass to 2.62(3) solar masses. This constraint, along with the spin
period and orbital parameters, suggests that this is a double neutron star
system, although we cannot entirely rule out a pulsar-white dwarf binary. This
pulsar is only detectable in roughly 45% of observations, most likely due to
scintillation. However, additional observations are required to determine
whether there may be other contributing effects.
