Scientific paper

We propose the first useful focusing X-ray observations of the radio pulsar PSR J1734-3333, a possible magnetar progenitor. This source, a 1.2 s radio pulsar, has inferred surface magnetic field 5.2x10^13 G, well above the quantum critical field and very close to those of bona fide magnetars. In timing observations made over 10 yr, we have recently measured a braking index for this source, n=1.3715+/-0.0077. So low a braking index is unprecedented and suggests effective magnetic field growth: this source may soon become -- or is already -- some form of magnetar. The requested short, exploratory observation could detect anomalous X-ray emission from this object and complete the hypothesized evolutionary chain between high-B rotation-powered pulsars and magnetars.
