A precise measurement of the mass of PSR J1950+2414

Millisecond pulsars are now known to have a much wider range of masses than assumed a few years ago (1.24-2.01 solar masses); there are indications that this range could be even wider. Therefore, when we attempt to measure the mass of a MSP, we never know what we will measure. PSR J1950+2414 is a new millisecond pulsar with an eccentric orbit discovered by the PALFA survey. The ob jective of this proposal is to make a dense set of timing measurements over one single 22-day orbit and measure the Shapiro delay. Combining this with ongoing observations which have already detected the precession of periastron for this system will yield a very precise mass measurement for this pulsar, and help determine the nature of its companion.
