ABSTRACT. We present a technique for simultaneous measurement of circular and linear polarization with the single-channel polarimeter, that is used in Crimean astrophysical observatory for many years. Methods and a computer program for data reduction is described. The algorithm is described, which have been used for photo-polarimetric monitoring of various astronomical objects cataclysmic variables, asteroids, comets.

“…This article is a continuation of the work on the Atlas of the mean light curves and catalogue of the characteristics of the long-period variable stars (Kudashkina, 2003;Chinarova and Andronov, 2000;Marsakova and Andronov, 1998) and these works were done in a frame of activity of the "Ukrainian Virtual Observatory" (Vavilova et al, 2011(Vavilova et al, , 2012 and "Inter-Longitude Astronomy" (Andronov et al, 2003). The "Stellar Bell" (pulsating stars) part of this campaign was reported by Andronov et al (2014).…”

Abstract. For nine Mira-type stars (o Cet, R Leo, S Car, U Her, X Oph, R Aql, RR Aql, S Ori, S Scl,) and one semi-regular star (L 2 Pup), the mean light curves have been obtained. The initial values of the brightness (observations) were fitted by a trigonometric polynomial of the statistically optimal order.The Fourier coefficients and the additional parameters (degree of the trigonometric polynomial, amplitude of the brightness, the maximal slope of ascending and descending branch, semi-amplitudes and initial epochs for the brightness maximum (minimum magnitude) of each harmonic contribution, etc., were given in the tables reported earlier (Kudashkina, 2015). In this study, we have received several interesting correlations between these parameters in the bands H and K. It was particularly noted the anomalous position on the figures of the star X Oph.The mean light curves of the investigated stars are commonly symmetric in the near infrared region (H and K).

“…One of them was the huge amount of data and the large amount of time spent on calculations. Only with the development of digital technologies in the field of image processing and, most importantly, software for scientifically focused processing of such digitized data this unrealistic task became feasible [18][19][20]. As a result, it became possible to perform a complete digitization of all astroplates, their processing, and extracting data of all objects fixed on them.…”

We present the results of asteroid images’ identification and creation of positional catalogs based on digitized photographic observations within the framework of the Northern Sky Survey (FON project). Namely, the cooperation between the Ukrainian Virtual Observatory and the Institute of Astrophysics of the Academy of Sciences of Tajikistan makes it possible to expand this work by involving numerous additional archives of digitized observations and processing services to obtain new original data about the small Solar system bodies. The Dushanbe part of the FON project is represented by about 1570 photographic plates obtained in 1985—1992 at the Gissar As- tronomical Observatory of the Institute of Astrophysics of the Academy of Sciences of Tajikistan. To the moment, their digitization and further scanning processing were completed, and a catalog of equatorial coordinates and stellar magnitudes for all registered objects on the plates was created. In parallel with solving the main task of the project to create a catalog of stars and galaxies, we analyzed the results of processing the plates to search for images of asteroids and comets and to create a catalog of their coordinates and magnitudes. More than 2200 positions of asteroids and comets were obtained with visual magnitudes from 7m to 16.5 m. All positions of the asteroids were compared with the ephemeris. A preliminary analysis of the O-C differences and their comparison with similar results obtained from the digitized observations of the Kyiv and Kitab parts of the FON project are conducted. The authors note some differences in the accuracy of the compared catalogs and also analyze the reasons for this and the possibilities of reducing their impact. In addition, the catalog includes several positions of Pluto and comets that were also identified in the negatives.
