Proposal Title: Timing of Pulsars Recently Discovered in 430-MHz Drift-Scan Search Data
ABSTRACT:
We request 150 hr of observing time to carry out regular timing observations spanning a 12-month baseline on
pulsars recently discovered in 430-MHz drift-scan search data. Data processing is approximately half complete.
Two of the seven pulsars discovered so far, J0610+21 and J1453+19, have periods of 55 and 5.8 ms and are likely
to be recycled pulsars, especially interesting because of their timing stability and likelihood of having binary
companions. Upon completion of the processing and conrmation observations (requested in a separate proposal),
we expect to have on the order of 20 new pulsars. From timing observations of these new pulsars, we will be able to
determine the spin and astrometric parameters of each pulsar to high accuracy, search for timing irregularities and
establish the existence of any orbiting companions.
