... Сегодня: 10 апреля 2016 г. Судя по условиям, которые обнаружили ученые вблизи звезды дзета-Зайца, пылевой диск может содержать астероиды, которые постоянно сталкиваются друг с другом. ... Дальнейшие наблюдения, проводившиеся в течение десяти лет, показали необычно высокую температуру диска, что объясняли либо близким расположением к звезде, либо существованием некоего другого источника инфракрасного излучения. ... Изучение диска поможет понять эволюцию нашей собственной планетарной системы. ...
... In spite of the good potential possibilities, some of the station "Dnepr" design characteristics did not allow us to apply the usual special IS radar measurement methods. ... Thus for IS signal measurements at the "Dnepr" station, we have developed special methods for recording and processing IS signals in order to determine plasma ionospheric parameters. ... Equations (4-5) from the basis for data post processing to obtain ionosphere parameters. ...

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

... Судя по условиям, которые обнаружили ученые вблизи звезды дзета-Зайца, пылевой диск может содержать астероиды, которые постоянно сталкиваются друг с другом. Если это сообщение найдет подтверждение, то это будет первый астероидный пояс, обнаруженный вне Солнечной системы, несмотря на то, что и планеты, и пылевые диски известны достаточно давно. О существовании пылевого диска вокруг этой звезды известно с 1983 года, по наблюдениям инфракрасной камеры спутника IRAS. ... Александр Симченко . ...
