... Великолепная семерка" - это семь радиотихих близких одиночных нейтронных звезд , открытых спутником РОСАТ. Первый объект, звезда Волтера , был открыт в 1996 г. То что это одиночная близкая нейтронная звезда стало ясно практически сразу по экстремально большому отношению рентгеновского потока к оптическому. ... В стандартных моделях затухания поля в коре нейтронных звезд получается, что чем горячее звезда, тем быстрее затухает поле (это связано с худшей проводимостью коры более горячего объекта). ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
