Scientific paper

We propose 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 5.2e13 G, well above the quantum critical field and very close to those of bona fide magnetars. In radio timing observations we have recently measured a stable braking index for this source, n=1.3715+/-0.0077. So low a braking index is unprecedented and suggests effective magnetic field growth, such that this source may soon become some form of magnetar. A previous short exploratory XMM observation revealed clear X-ray emission from this source. Here we request a longer follow-up observation in order to determine the source's spectral properties and to search for pulsations.
