IMPROVED EPHEMERIS OF POORLY STUDIED ECLIPSING BINARY GSC 3950-00707 = 2MASS J20355082+5242136
Journal Title: Odessa Astronomical Publications - Year 2017, Vol 30, Issue
Abstract
We made our CCD-observations of GSC 3950-00707 by using the telescope Celestron-14 of Vihorlat Observatory and Astronomical Observatory on Kolonica Saddle. The moments of minima were calculated by using the symmetrical polynomial fit. We also analyzed the observations from automated surveys ASAS-SN and found 3 mean minima by using trigonometrical polynomial fit. The analysis of our observations and data from the surveys allows to conclude that it is the W UMa-type variable and its published period value is not accurate. We analyzed the O-C curve and corrected the elements.

GRAVITY-DRIVEN ACCELERATION AND KINETIC INFLATION IN NONCOMMUTATIVE BRANS-DICKE SETTING
By assuming the spatially flat FLRW line-element and employing the Hamiltonian formalism, a noncommutative (NC) setting of the Brans-Dicke (BD) theory is introduced. We investigate gravity-driven acceleration and kinetic...
THE KINEMATICS PARAMETERS OF THE GALAXY USING DATA OF MODERN ASTROMETRIC CATALOGUES
Based on the Ogorodnikov-Milne model, we analyze the proper motions of XPM2, UCAC4 and PPMXL stars. To estimate distances to the stars we used the method of statistical parallaxes herewith the random errors of the distan...
BALDONE 1.2M TELESCOPE PLATE ARCHIVE - HIDDEN RESERVES OF THE FON PROJECT
The plate archive of the 1.2 m Baldone telescope (Latvia) has approximately 780 and 4660 astronegatives exposed in 1967-1993 in the U (ZU21 + UG1 filter plates) and V (A600N + ZS17 filter films) closed to Johnson system...
CROSS-MATCHING OF VERY LARGE CATALOGS
Modern astronomical catalogs and sky surveys, that contain billions of objects, belong to the “big data” data class. Existing available services have limited functionality and do not include all required and available ca...
THREE GIANTS – MEMBERS OF THE OPEN CLUSTER M 67
We determined the atmospheric parameters and chemical composition of the three giants, which are members of the open cluster M 67. The high resolution spectra (R = 60 000) were obtained with the echel...
