During the 2014–2015 mutual events season, Institut de Mécanique Céleste et Calcul des Éphémérides (IMCCE), Paris, France, and Sternberg Astronomical Institute (SAI), Moscow, Russia, led an international observation campaign to record ground-based photometric observations of Galilean moon occultations eclipses. We focused on processing complete data base compute new accurate astrometric positions. used our method derive positions from light curves events. developed model eclipses, while...
Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected ESA's mission remain recoverable after their discovery. An observation campaign on potentially hazardous asteroid (99 942) Apophis was conducted during asteroid's latest period of visibility, from 12/21/2012 to 5/2/2013, test coordination and evaluate overall performance Gaia-FUN-SSO . The 2732 high quality astrometric...
We discuss the results of an investigation astrometric positions extragalactic radio sources from a list for International Celestial Reference Frame. About 300 fields around were observed during years 2000-2003. The observations performed mainly using two telescopes equipped with CCD cameras at TUG, Turkey (Russian-Turkish Telescope – RTT150) and YAO (1 m telescope), (Kunming, China). mean accuracies measured are 38 mas in right ascension 35 declination. A comparison between optical...
Abstract The paper describes observations of fast-moving near-Earth asteroids (NEAs) made with the small ground-based telescopes National Time Service Center Chinese Academy Science (NTSC CAS) and Research Institute “Mykolaiv Astronomical Observatory” (RI MAO) by rotating-drift-scan CCD (RDS CCD) technique. This technique is used to obtain point images both studied objects reference stars. results ongoing follow-up NEAs are discussed. residual differences ( O – C ) between observed...
Main objective of the study is orbit refinement Near-Earth Objects (NEOs) as part global task asteroid-cometary hazard. We present latest results ongoing high-precision astrometric follow-up observations NEOs using Mykolaiv Observatory KT-50 telescope Mobitel Complex that equipped Alta U9000 CCD camera. feature objects this fast moving in field view. That circumstance makes impossible to observe point images and obtain their precise coordinates by classical methods observation. used modified...
Abstract The apparent velocities of near-Earth asteroids (NEAs) are usually high when they pass by Earth. Observing these fast-moving objects with long exposure times would cause their images to streak and significantly decrease the precision astronomical measurements. rotating-drift-scan (RDS) charge-coupled device technique is a promising approach observe NEAs during close approaches By rotating camera telescope, an NEA can be observed in time delay integration mode. This allows asteroid...
The results of double stars observations at Nikolayev Observatory during 2013-2014 are presented. Washington Double Stars Catalogue (WDS) was used for observation program composing. volume obtained with usage two telescopes equipped CCD-cameras. Precise modern epoch CCD-observations allowed to make new proper motion values. position angles and separations 214 were measured. Results going be submitted WDS.
The new reductions of available photographic plates UkrVO digital archive containing images selected minor planets were conducted. Data processing these carried out to check the possibility obtaining positions with high accuracy in system Tycho2/UCAC4 reference catalogues. Archives Research Institute “Nikolaev Astronomical Observatory” (NAO) and Main Observatory ofNationalAcademyof Science (MAO) used. We have chosen near 60 from archives. Observational epochs range 1974 1991. Usually, there...
Представлены результаты наблюдений двойных звезд, наблюдавшихся в НИИ «НАО» на протяжении 2013-2016 годов. Выполнена астрометрическая редукция полученных кадров до получения экваториальных координат компонентов и кратных систем момент наблюдения. Комбинация ПЗС-положений с другими каталогами Страсбургской базы позволили определить новые значения собственных движений звезд. Для 214 были измерены параметры взаимной конфигурации (позиционный угол угловое расстояние). Приведен анализ результатов...
The study of meteoroids and the phenomenaarising from their entry into Earth's atmosphere is ofconsiderable scientific practical interest to obtain data onthe origin evolution solar system, thephysics planetary atmospheres, solve problem ofproblem asteroid-cometary-meteoroid hazard. Today themost effective informative are photometric spectralstudies meteor phenomena, which provide information chemical composition physical properties (density,combustion temperature, etc.) that allow us...
Double and multiple star systems are thesource of unique information for determining the parame-ters formation models testing stellar modelsevolution. Therefore observations measuring theirmutual configuration parameters is still important.Observations double at theResearch Institute “Mykolaiv Astronomical Observatory”(RI MAO) were performed with different telescopes since2013. In addition, we also have an observational databaseand proceeding results fields in open clusters vicini-ty, which...
One of the methods determining orientation parameters dynamic and kinematic coordinate systems is to use long-term series ground-based observations selected asteroids. For achievement best accuracy link high precision uniformly covering asteroids orbit are necessary. The analysis available was made with usage MPC database. value true anomaly at moment observation as parameter covering. It shown that there orbital segments without precise observations. This taken into account when forming...
Today there are several open photometric databases containing important information for the study of physical properties asteroids. These based on results various measurements different sets objects. The statistical correlations between could significantly expand list asteroids with known parameters. We present comparative analysis determination albedo, diameters and absolute magnitudes five sources (AKARI, IRAS, NEOWISE, HORIZONS Pan-STARRS1). infrared survey WISE (relatively to is NEOWISE...
