By performing timing observations, an international group of astronomers has measured the mass of two binary millisecond pulsars designated PSR J1949+3106 and PSR J1950+2414. The results could be essential in order to unveil the evolutionary status of these two objects. The research is detailed in a paper published July 11 on arXiv.org.
