Gravitational dynamics of a relativistic binary pulsar and a probe of radio pulsar intermittency

The thesis uses observations of radio pulsations from a neutron star in a binary orbit around a white dwarf star to understand the motion of the star as postulated by Einstein's General theory of Relativity. The pulsar's orbit is seen to wobble as a result of the fast rotation of the white dwarf, something seen for the first time in binary star systems. The second part of the thesis deals with the development of a fully robotic system of observation and data analysis with the Molonglo radio telescope to search for radio pulsations from other yet undiscovered neutron stars.
