Digital Preservation and Web Access to the Konkoly Observatory Schmidt Telescope Plate Archive

ACM Computing Classification System (1998): J.2.The digital preservation of the Konkoly Observatory Schmidt telescope plates, as well as the web access to the plate previews, aim for the preservation of this scientific heritage and the re-use of the astronomical photographic plates in time domain astronomy. The photographic plates used as detectors and information storage at astronomical observations with the Konkoly Schmidt telescope had been obtained in the period 1962–1996. The work on the digital plate preservation and web access started in 2001 with creation of an electronic plate catalogue and the digitization of selected representative plates as well as with interlinking of the publishing in Konkoly Observatory Information Bulletin on Variable Stars (IBVS) with the Wide-Field Plate Database (WFPDB) developing in Sofia. We describe the process of the digitization of the Konkoly Schmidt telescope plates.This work is supported by the bilateral project between the Bulgarian Academy of Sciences and the Hungarian Academy of Sciences and partially by the grants BG NSF DO-02-273 and BG NSF DO-02-275

Magnetic fields in single late-type giants in the Solar vicinity: How common is magnetic activity on the giant branches?

We present our first results on a new sample containing all single G,K and M giants down to V = 4 mag in the Solar vicinity, suitable for spectropolarimetric (Stokes V) observations with Narval at TBL, France. For detection and measurement of the magnetic field (MF), the Least Squares Deconvolution (LSD) method was applied (Donati et al. 1997) that in the present case enables detection of large-scale MFs even weaker than the solar one (the typical precision of our longitudinal MF measurements is 0.1-0.2 G). The evolutionary status of the stars is determined on the basis of the evolutionary models with rotation (Lagarde et al. 2012; Charbonnel et al., in prep.) and fundamental parameters given by Massarotti et al. (1998). The stars appear to be in the mass range 1-4 M_sun, situated at different evolutionary stages after the Main Sequence (MS), up to the Asymptotic Giant Branch (AGB). The sample contains 45 stars. Up to now, 29 stars are observed (that is about 64 % of the sample), each observed at least twice. For 2 stars in the Hertzsprung gap, one is definitely Zeeman detected. Only 5 G and K giants, situated mainly at the base of the Red Giant Branch (RGB) and in the He-burning phase are detected. Surprisingly, a lot of stars ascending towards the RGB tip and in early AGB phase are detected (8 of 13 observed stars). For all Zeeman detected stars v sin i is redetermined and appears in the interval 2-3 km/s, but few giants with MF possess larger v sin i.Comment: 4 pages, 3 figures, Proceedings IAU Symposium No. 302, 201

Values and basic beliefs of working and non-working students

The article is prepared on the basis of empirical data obtained from a sample of senior students divided into two groups – a group of working and a group of non-working students. They studied and compared social values and individual priorities, as well as basic beliefs. It is shown that both student samples are generally characterized by the same average overall level of social values (3.9 points out of 7 possible) and a low overall level of individual priorities, although it is higher for working students (2.1 vs. 1.8 points). The priority of social values over individual values was found in both groups. Intergroup differences in the value of “power” are established: its indicator is higher among working students; non-working students attach more importance to independence. Working students, in comparison with non-working students, have a higher individual significance of conformity and achievements. Students of both groups have a high level of conviction in their own worth and luck, but the world seems to them more unfair than fair. Significant intergroup differences in none of the five basic beliefs were revealed
