Max Planck Scientists Find Evidence for Stellar Companion's Activity Cycles

... Only in 2014 could the pulsar now known as “PSR J2339–0533†be identified through its pulsed radio emission. The observations at radio wavelengths are hampered through the interaction of the pulsar with its stellar partner. The pulsar's radiation heats the companion and slowly vaporizes it. This causes clouds of gas to drift through the binary system, which absorb the radio emission and temporarily make the pulsar invisible. To completely characterize the system, regular observations over several years would be required.
