ПЛАНЕТА ОЗИРИС . ... Озирис оказался первой экзопланетой, которая была исследована как с помощью метода доплеровской спектроскопии, когда измеряются небольшие смещения линий в спектре звезды, вызванные гравитационным влиянием планеты, так и с помощью наблюдения т.н. транзитов, т.е. проходов планеты по диску звезды. ...
