Whilst no radio emission was detected from any of the targets, significant upper limits were placed on the radio luminosities that are below the luminosities of previously detected ultracool dwarfs. Combining our results with those from the literature gives a detection rate for dwarfs in the spectral range M7 тАУ L3.5 of тИ® 9%. ...

... A method to detect non-radial pulsations of CP stars is suggested. ... The opportunity is noted to get an information on spatial structure of non-radial oscillations from the analysis of radial velocities of chemical element lines, concentrated in the spots. To detect and identify the modes of non-radial oscillations of average grades it is suggested to use the methods of line profile analysis applying thee to the lines observed in the local spots on the stellar surface. ...

FEATURES OF THE HYDROGEN DISTRIBUTION AROUND LUNAR CRATERS PROCLUS AND KEPLER. ... In result of analysis of the data Lawrence and Feldman constructed the hydrogen distribution on the lunar surface [1]. ... However, the authors shown, that EN flux data features may be explained by other element abundance in the lunar soils, namely: Si, Ca, Gadolinium (Gd), Samarium (Sm) and Fe. ... Using of the Feldman's interpretation of the Lunar Prospector data [8], we constructed hydrogen distribution map (Fig.1). ...
