Full description

We propose timing observations of southern double neutron star (DNS) systems to obtain precise estimates\r
of the component masses and thus increase the statistics of neutron star mass distribution. The improved\r
sensitivity of the Ultra Wideband Low (UWL) receiver will provide a 3X increase in the precision of the time\r
of arrivals (ToAs) of the pulses compared to the multibeam data. This has the potential to perform quick\r
measurements of masses for a number of binary systems in the next 1-2 years. We will also use MeerKAT\r
observations at crucial orbital phases to increase our chances of mass measurements. Increase in the number\r
of measured NS masses has significant implications for understanding NS internal structure and for stellar\r
and binary evolution physics.
