摘要: The mode-switching pulsar PSR B0943+10 has been extensively studied in the radio band for many years and, more recently, it found to vary also X-rays, with a flux anticorrelated emission. Here we review results of long observations carried out XMM-Newton and LOFAR, LWA Arecibo telescopes 2014. These support scenario which both unpulsed non-thermal emission, likely magnetospheric origin, pulsed thermal emission from small polar cap (~1500 m2) strong non-dipolar magnetic field (~ 1014 G), are present during modes intensity correlated way.
