Меркурий . Хотя эта маленькая планета расположена близко к Солнцу и подвергается воздействию эсктремальных температур, она хорошо сохранила черты ландшафта времен формирования планет - примерно 4,5 млрд. лет назад. ... Другое (и, видимо, последнее) отличие: на Меркурии встречаются уступы (эскарпы) длиной в сотни километров и высотой до 1-2 км, вытянутые по меридианам. ...

Magnetic Stars, 2011, pp. ... Since the discovery of spectral variations in the Hg II line of the star And, a few other HgMn stars have been reported to present line profile variations. In this work we present preliminary results of a study of spectral variability in 28 singlelined HgMn stars. Using between two and six spectra per star, obtained with the FEROS spectrograph of the ESO, we quantitatively analyze the line profile variations for various chemical elements. ...
