Unfortunately, some important, mainly historical photometric or spectroscopic data exist only in the form of published phase diagrams. In this article we would like to present a new method of the analysis of these phase diagrams. ... The period of their variations is controlled by the rotation of the star. ...

He, C, N, and O Abundances in an Ensemble of Galactic PNe (in russian) Astronomy Letters,, 35 , 518-533 ( 2006 ) Original Russian Text are published in Pis'ma v Astronomicheskii Zhurnal , 35 , No. 8, pp. 563-573 ( 2009 ) . ... The He abundance is determined with an accuracy of 0.06 dex, while the errors in the C, N, and O abundances are 0.1-0.2 dex. ... The elemental abundances in PNe of various Galactic subsystems and the Magellanic Clouds have been analyzed. ...

... ATNF Colloquium . Found: The Original 1945 Records of Australian Radio Astronomy - Collaroy Observations . ... In July 2014, Miller Goss, Ron Ekers and Helen Sim found the original records of the first published Australian radio astronomy observations. These were obtained by Joseph L. Pawsey and Ruby Payne-Scott in early October 1945. The observations gave strong evidence of a hot million degree corona as well as frequent radio bursts. ... today * ATNF | ...

... We performed photometry on both the original and deconvolved images of NGC 6352. ... Aperture photometry was performed on all stars identified in the deconvolved master frames with aperture radii of 4 and 5 pixels for the F555W and F785LP images respectively. ... Fig. 2 indicates that the scatter about the mean faint star sequence is much smaller for the aperture photometry of the deconvolved images than for the PSF fits to the original images. ...

The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ... Galileo's Observations of Jupiter's Moons . ... Jupiter . ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...
