Несколько слов об Октае . ... 23 года я проработал под руководством Октая в лаборатории физики звездных атмосфер - сначала в Шемахинской обсерватории, потом в Баку, в Институте физики. ... С Октаем я делал дипломную работу - и там (это был 1967 год) написал (после разговоров с шефом, конечно), что нейтронные звезды могут быть источником периодического рентгеновского излучения (из-за вращения и магнитного поля). ... В начале марта Октай приезжал в Баку, был в своей бывшей лаборатории. ...

True Color Image Gallery: Galactic SNR | Magellanic Cloud SNR . ... Chandra Proposer's Guide pile up section ] During frame readout, the ACIS CCDs take 40 microsec to (parallel) transfer the charge by one pixel. As a result of this, each frame readout, each pixel is exposed for 40 microsec to a source (plus cosmic X-ray background) at each location along its column. ... Note also that the image does not just trail, it extends along the whole column. ... Chandra Supernova Remnant Catalog . ...

Пульсары . Слово 'пульсар' произошло от начальных букв английских слов Pulsating Sources of Radioemission - пульсирующие источники радиоизлучения. Это объекты характеризуются очень короткопериодическими - от 1,5 миллисекунд до нескольких секунд - всплесками излучения в радиодиапазоне электромагнитного излучения . Однако у некоторых пульсаров обнаружено излучение в видимом, ультрафиолетовом и даже рентгеновском диапазонах. К настоящему времени открыто более тысячи пульсаров. ...
