TLDR
In this paper, a radio millisecond pulsar (MSP) was detected in a low-mass x-ray binary (LMXB) system with an optically identified companion star.Abstract:
Radio pulsars with millisecond spin periods are thought to have been spun up by the transfer of matter and angular momentum from a low-mass companion star during an x-ray-emitting phase. The spin periods of the neutron stars in several such low-mass x-ray binary (LMXB) systems have been shown to be in the millisecond regime, but no radio pulsations have been detected. Here we report on detection and follow-up observations of a nearby radio millisecond pulsar (MSP) in a circular binary orbit with an optically identified companion star. Optical observations indicate that an accretion disk was present in this system within the past decade. Our optical data show no evidence that one exists today, suggesting that the radio MSP has turned on after a recent LMXB phase.read more

TL;DR: Observations of accretion-powered, millisecond X-ray pulsations from a neutron star previously seen as a rotation- powered radio pulsar show the evolutionary link between accretion and rotation-powered millisecond pulsars, but also that some systems can swing between the two states on very short timescales.

TL;DR: The LOw Frequency ARray (LOFAR) as mentioned in this paper is a radio interferometer operating in the lowest 4 octaves of the ionospheric "radio window": 10-240 MHz, that will greatly facilitate observing pulsars at low radio frequencies.
