Serbian Virtual Observatory and Virtual Atomic and Molecular Data Center (VAMDC)

In this lecture we review recent developments in Serbian Virtual Observatory (SerVO) as well as its relation with the European FP7 project: Virtual Atomic and Molecular Data Center VAMDC. Main components of SerVO are going to be the archive of photographic plates, database of Stark broadening parameters and stellar evolution database. Photographic plates were obtained at Belgrade Observatory from 1936 to 1996. Data for Stark broadening were obtained using semiclassical perturbation and modified semiempirical theories mainly in collaboration with Paris Observatory, and we are organizing them now in the STARK-B database, which will enter also in VAMDC, and will have a mirror site in SerVO. Serbian Virtual Observatory will contain as well a mirror of Darthmouth Stellar evolution database with improvements and VO compatible outputs. 1. VIRTUAL OBSERVATORIES AND SERBIAN VIRTUAL OBSERVATORY The creation of datasets, connected with the space missions, in the NASA centers in early 90 ́s, and the huge quantity of data obtained in large all sky surveys (2MASS and SDSS) in the mid-90 ́s, available for the general use, posed the problem how to organize their search and use them for scientific DARKO JEVREMOVIĆ et al. 56 investigations. The idea of virtual observatory originated from the efforts to solve this problem. Today, the objective of virtual observatories is not only to find, retrieve and analyze astronomical data from ground and space based telescopes worldwide, but also to combine research in different areas of astrophysics, like e.g. multi wavelength astrophysics, archival research, survey astronomy. They also provide data analysis techniques, common standards, wide network bandwidth and state of the art analysis tools. For the differences of classic observatories which have telescopes for gathering electromagnetic radiation or particles, instruments for analyzing and recording as well as different facilities for support of operation, the virtual observatories consist of data centers, loads of astronomical data, software systems and processing capabilities. International Virtual Observatory Alliance (IVOA, www.ivoa.net), is formed in June of 2002, with objective to facilitate the international coordination and collaboration necessary for the development and deployment of the tools, systems and organizational structures necessary to enable the international utilization of astronomical archives as an integrated and interoperating virtual observatory. So its activity mainly focuses on the development and establishing of standards. The current set of standards as well as recommended ways of implementing them can be found at http://www.ivoa. net/Documents/. European Virtual Observatory EuroVO is an organization which aims at deploying VO in Europe. It is organized in three main parts: Facility center (VOFC) provides the EURO-VO with a centralized registry for resources, standards and certification mechanisms as well as community support for VO technology take-up and dissemination and scientific program support using VO technologies and resources. Technology center (VOTC) coordinates a set of research and development projects on the advancement of VO technology, systems and tools in response to scientific and community requirements. Data Center alliance (DCA) is an alliance of European data centers who will populate the EURO-VO with data, provide the physical storage and computational fabric and who will publish data, metadata and services to the EURO-VO using VO technologies. Serbian Virtual Observatory (SerVO – http://servo.aob.rs/~darko/) is a project, whose funding was approved through a grant TR13022 from Ministry of Science and Technological development of Republic of Serbia aiming to achieve the following goals: 1) establishing SerVO and join the EuroVO and IVOA; 2) establishing SerVO data Center for digitizing and publishing in VO photoplates from the archive of AOB, and publishing other observational, theoretical, and simulated data obtained at Serbian observatories or by staff of Serbian observatories; 3) development of tools for visualization of data.
