Астрономия и Космос Небесные тела Звезды . А строномы объявили о новых исследованиях Полярной звезды на проходившей на прошлой неделе встрече Американского Астрономического общества в Рочестере, Нью-Йорк. Астрономы использовали оптический интерферометр (Navy Prototype Optical Interferometer - NPOI) в Аризоне, для того чтобы измерить размеры звезды, и обнаружили, что ее диаметр превосходит диаметр Солнца в 46 раз. Астрономам давно известно, что Полярная звезда относится к классу цефеид . ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...
