... During the analysis of the surveys carried out on RATAN-600, it was found that almost one fifth of the detected sources shows significant radio flux variations. ... We used the data from "Cold" radio surveys carried out with RATAN-600 in 1980-1994 to search for radio sources with significant flux variability. ... On possibility of detection of variable sources using the data of Cold surveys carried out on RATAN-600. ... Detection of Variable Sources Using the Data of "Cold" Surveys. ...

... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...

... OB used an idea to take into account the known gravitational lensing time delay to get combined radio and optical light curves and then to use them for determination of the p ossible radio-from-optical time delay. ... We fix some moment of time as t0 . ... So we can calculate the needed correction: S (t) = V · (t - t0 ) 365d (2) to b e added to dates in the optical light curves: ti = ti + S (ti ) (3) Assuming that a p ortion of radio flux decreases as a p ower-law function of time with exp onent . ...

Peremennye Zvezdy", . ... Star Name: . 2MASS 20031968+6504085 . ... The variability of 2MASS 20031968+6504085 was discovered using a series of 58 unfiltered CCD images obtained with the MASTER-Amur robotic telescope (D = 400 mm, F = 1000 mm, Apogee Alta U16m CCD camera; Lipunov et al. 2010) between January 26 and March 27, 2011. After the standard calibration (dark subtraction, flat fielding) the images were processed with the VaST variability search software (Sokolovsky Lebedev 2005). ...
