We report on our participation to the European project ELSA and on the results of the project RAVE. An overview article presents the results to the Slovenian audience, and discusses our involvement and leadership in these projects. The conference Slovenia and Space: yesterday, today and tomorrow has been also organized by T. Zwitter and A. Gomboc.
B.02 Presiding over the programming board of a conference
COBISS.SI-ID: 336257During the whole project we had a nearly constant presence in the media. We organized and wrote the monthly broadcast Frequency X on the Val 202 national radio station. There were a number of interviews, public lectures and other events connected with the International Year of Astronomy. Astronomy-related questions (and answers) have been put on boards in the public bus transport in Ljubljana, together with publication of a related booklet. The interview on the national TV (see below) received much of the public attention.
D.10 Educational activities
COBISS.SI-ID: 318337T. Zwitter had an invited lecture at the symposium of the International Astronomical Union (IAU) 254: The Galaxy Disk in Cosmological Context. The results of the second RAVE data release have been presented, together with their scientific use and plans for the next three years. The need for reliable calibration relations and constant quality checks has been emphasized, with the RAVE survey as a case study. Another invited lecture has been presented by M. Steinmetz. The proceedings join both to a common paper.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 326785ELSA (European Leadership in Space Astrometry) is a 6th Framework program of the EU. It is part of the preparation for the Gaia mission of the European Space Agency. This is one of the largest missions of ESA in this decade. It is devoted to revealing the structure and history of our Galaxy. We coordinated one of the national nodes of the project (see http://www.astro.lu.se/ELSA/index.html).
D.01 Chairing over/coordinating (international and national) projects
COBISS.SI-ID: 323201Identification of double-lined spectra of binary stars is not limited by the rare occurrences of eclipses. When the spectrum is properly classified, its atmospheric parameters can be calculated by comparing the spectrum with the best fit atmosphere model. We present the classification and binary discovery method based on the correlation function analysis and determine their essential atmospheric parameters. Large number of such estimates and the fact that RAVE consists of a magnitude selected sample without any color cuts makes it suitable for a binary star population study.
