Resumo

Магнитары — нейтронные звезды, обладающие сверхсильными магнитными полями, которые могут заметно превышать 1015 Гс. В некоторых из них (так называемых источниках мягких повторяющихся гамма-всплесков, soft gamma repeaters — SGRs) время от времени происходят процессы мощного энерговыделения, вызывающие необычайно сильные всплески электромагнитного излучения. Считается, что эти всплески связаны с наличием сверхсильных магнитных полей. Несмотря на множество гипотез, их механизм остается загадкой. В послесвечении всплесков выявлены квазипериодические осцилляции (КПО). Они трактуются как собственные колебания звезды, возбуждаемые при всплесках, и используются для диагностики всплесков. Показана существенная неполнота теорий, использованных для интерпретации КПО.Статья для специального выпуска ЖЭТФ, посвященного 130-летию П. Л. Капицы
