Title |
The Pulsar Mass Distribution: Recent Developments and Ramifications for the Dense Matter Equation of State | |||||
Coauthors | Freire, Paulo | |||||||
Abstract |
Neutron star mass measurements are motivated by central problems in physics such as the super-nova explosion mechanism and the properties of dense nuclear matter. In my talk I will elaborate on some recent advances in pulsar mass measurements and their ramifications for the nuclear matter EoS and stellar evolution. In particular, I will review the measurements of high mass neutron stars in binary millisecond pulsar systems and then describe a new class of binaries with high eccentricities that may provide valuable complementary insights for the EoS. Finally, I will elaborate on the ramifications of these measurements for the determination of the underlying pulsar mass distribution. |

Title |
Pulsar-White Dwarf Systems as Gravity Labs | |||||
Coauthors | ||||||||
Abstract |
An outstanding question in modern Physics is whether general relativity is a complete description of gravity among bodies at macroscopic scales. Currently, the best experiments supporting this hypothesis are based on high-precision timing of radio pulsars. I will review recent advances in the field, focusing on compact binary millisecond pulsars with white-dwarf companions. These systems, if modelled properly, provide an unparalleled test-ground for physically motivated alternatives to GR that deviate significantly in the strong-field regime. Recent improvements in observing techniques and advances in our understanding of WD interiors have allowed for a series of precise mass measurements is such systems. These masses, combined with high-precision radio timing of the pulsars, result to stringent constraints on the radiative properties of gravity, qualitatively very different from what was available in the past. |
