Timing the Six Millisecond Pulsars in M62

Abstract

We recently reported the discovery of three new binary millisecond pulsars (MSPs) in the globular cluster M62 (NGC 6266, Jacoby et al. 2002), the first new pulsars detected with the Green Bank Telescope. Along with the three previously known MSPs in M62 (Possenti et al. 2001), our discoveries bring the total number of detected pulsars in this cluster to six. Only two other clusters contain more known pulsars. We are requesting a total of 66 hours (including setup and calibration time) of GBT observations, spread out over the next 11 months, to obtain the timing solutions for these six pulsars. This timing program will allow us to place very useful constraints not only on the intrinsic properties of the pulsars, such as magnetic field strengths and characteristic ages, but also on several key properties of the host cluster, including central density and initial mass function.
