Black widows are extreme millisecond pulsar binaries where the pulsar wind ablates their low-mass companion stars. Their optical light curves vary periodically due to the high irradiation and tidal distortion of the companion, which allows us to infe

Einstein@Home Discovery of the Gamma-ray Millisecond Pulsar PSR J2039-5617 Confirms Its Predicted Redback Nature

Publikováno v: MNRAS 502 915 (2021)

The Fermi Large Area Telescope gamma-ray source 3FGL J2039.6$-$5618 contains a periodic optical and X-ray source that was predicted to be a "redback" millisecond pulsar (MSP) binary system. However, the conclusive identification required the detectio

Optical, X-ray, and $\gamma$-ray observations of the candidate transitional millisecond pulsar 4FGL J0427.8-6704

Autor: Kennedy, M. R., Breton, R. P., Clark, C. J., Dhillon, V. S., Kerr, M., Buckley, D. A. H., Potter, S. B., Sánchez, D. Mata, Stringer, J. G., Marsh, T. R.

We present an optical, X-ray, and $\gamma$-ray study of 1SXPS J042749.2-670434, an eclipsing X-ray binary which has an associated $\gamma$-ray counterpart, 4FGL J0427.8-6704. This association has led to the source being classified as a transitional m
