We present radio, optical, ultraviolet, and X-ray observations of the isolated, thermally emitting neutron star RX J0720.4-3125 using the Parkes radio telescope, the Very Large Array, the Hubble Space Telescope, and the Chandra X-Ray Observatory. From these data we show that the optical/UV spectrum of RX J0720.4-3125 is not well fitted by a Rayleigh-Jeans tail as previously thought but is instead best fitted by either a single nonthermal power law or a combination of a Rayleigh-Jeans tail and a… 

The proper motion of the isolated neutron star RX J1605.3+3249

A Coherent Timing Solution for the Nearby Isolated Neutron Star RX J1308.6+2127/RBS 1223

We present a phase-connected timing solution for the nearby isolated neutron star RX J1308.6+2127 (RBS 1223). From dedicated Chandra observations as well as archival Chandra and XMM-Newton data

The spectral and temporal variability of the isolated X-ray pulsar RX J0720.4-3125

The radio-quiet thermally emitting X-ray pulsar RX J0720.4-3125 belongs to a group of seven isolated neutron stars (often referred to as the ``Magnificent Seven"). They share similar properties such

The Distance to the Isolated Neutron Star RX J0720.4–3125

We have used a set of dedicated astrometric data from the Hubble Space Telescope to measure the parallax and proper motion of the nearby neutron star RX J0720.4-3125. At each of eight epochs over 2

Isolated neutron stars: magnetic fields, distances,and spectra

Abstract We present timing measurements, astrometry, and high-resolution spectra of a number of nearby, thermally emitting, isolated neutron stars. We use these to infer magnetic field strengths and
