Английская Википедия:GPM J1839−10
Шаблон:Short description GPM J1839−10[1] is a potentially unique[2] ultra-long period magnetar[3][4] located about 15,000 light-years away from Earth in the Scutum constellation, in the Milky Way. It was discovered by a team of scientists at Curtin University using the Murchison Widefield Array.[5][6] Its unusual characteristics violate current theory and prompted a search of other radio telescope archives, including the Giant Metrewave Radio Telescope and the Very Large Array, which revealed evidence of the object dating back to 1988.[5] The signature of the object went unnoticed because scientists did not know to look for its unusual behavior.[5]
The current understanding of neutron stars is that below a certain rate of rotation, called "the death line", they cease emissions. Uniquely, not only does GPM J1839−10 have an extremely slow rotation of approximately twenty-two minutes, it emits bursts of radio waves lasting up to five minutes, for which there is currently no generally accepted explanation.[5][4][6][7][8]
