标题： Search for binary companions around millisecond pulsars

摘要： 人们认为，旋转周期约为30毫秒甚至更短的射电脉冲星通过过去从其双星伴星（或过去的伴星）吸积物质转移角动量而获得了如此高的自转速度。 大约35%的毫秒脉冲星已被确认为孤立的，其中一些可能实际上处于双星系统中——要么是由于定时不够精确而未能获得轨道特征，要么是处于非常宽的双星系统中，只有通过非常精确的定时才能揭示，如PSR J1024-0719的情况。 这促使了一项识别银河系场中毫秒脉冲星可能伴星的练习。 这项练习甚至有可能发现毫秒脉冲星自身的光学辐射。 任何可能的双星伴星的发现都将随后引发有动力的脉冲星定时活动，以确认双星性质并限制轨道参数。 显示英文摘要

摘要： It is believed that the radio pulsars rotating at spin periods of about 30 millisecond or even lower got such high spins through the transfer of angular momentum by accreting matter from their binary companions (or past companions) in the past. Around 35% of MSPs are known to be isolated, some of the which might actually be in binaries - either not timed very well to obtain the signature of the orbit or in extremely wide binaries that can be revealed only through very accurate timing, as in the case of PSR J1024-0719. This has motivated an exercise to identify probable candidates of companions of MSPs in the Galactic field. This exercise has even the potential of discovering optical emission from MSPs themselves. Discovery of any possible binary companion will be followed by motivated pulsar timing campaigns to confirm the binary nature and to constrain orbital parameters.
