Search and study of asteroids from the digitized first Byurakan survey using virtual observatory tools

Abstract : The Digitized First Byurakan Survey (DFBS) is the digitized version of the Markarian Survey and it is the largest spectroscopic survey by its sky coverage (17, 000 deg2) and by the number of spectra (∼40,000,000). It provides a unique possibility to compare objects between different epochs, as the observations have been carried out in 1965–1980 and it complements the epochs between POSS1 and POSS2. DFBS is especially efficient for discovery and study of moving objects, such as asteroids. On the other hand, searching with a “naked eye” in planetary data archives takes a considerable time. Therefore, such work must be done in an automatic way. However, the planetary data archive is subject to a constant change (new elements, new version of analysis, new parameters). Furthermore, there are several archives for the same object, thus, obtaining reliable information requires a sequential search of several different archives. Workflows developed in the frame of the virtual observatories (VO), can use all collections of integrated astronomical data archives and software tools that utilize computer networks to create an environment in which research can be conducted. In this paper, we have used the VO tool SkyBoT for searching for asteroids in the DFBS and other archives and we have developed a workflow using a selection of the VO tools in the case of the hot topic of asteroids.
