GBT Exploratory Time Observations of the Double-Pulsar System PSR J0737-3039
S. Ransom, P. Demorest, V. Kaspi +2
We report results from Exploratory Time observations of the double-pulsar system PSR J0737-3039 using the Green Bank Telescope (GBT). The large gain of the GBT, the diversity of th…
Search for Discrete Refractive Scattering Events
R. Ramachandran, A. A. Deshpande, B. W. Stappers
We have searched for discrete refractive scattering events (including effects due to possible non-multiple diffractive scattering) at meter wavelengths in the direction of two clos…
Kinematics of Radio Pulsars
R. Ramachandran
Observations of proper motions and their statistical analyses show that the predominant number of pulsars have velocities of the order of 200-250 km/sec. The pulsar population exhi…
Puzzling Pulsars and Supernova Remnants
D. R. Lorimer, R. Ramachandran
The fact that the majority of the youngest radio pulsars are surrounded by expanding supernova remnants is strong evidence that neutron stars are produced in the supernovae of mass…
The observational evidence pertinent to possible kick mechanisms in neutron stars
A. A. Deshpande, R. Ramachandran, V. Radhakrishnan
We examine available observations on pulsars for evidence pertaining to mechanisms proposed to explain the origin of their velocities. We find that mechanisms predicting a correlat…
