The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is a variability survey of the Milky Way bulge and an adjacent section of the disk carried out from 2010 on ESO Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey will eventually deliver a deep near-IR atlas with photometry and positions in five passbands (ZYJHKS) and a catalogue of 1−10 million variable point sources – mostly unknown – that require classifications. -
Pulsating Variable Stars and the Hertzsprung-Russell Diagram
- !% ! $1!%" % Studying intrinsically pulsating variable stars plays a very important role in stellar evolution under- standing. The Hertzsprung-Russell diagram is a powerful tool to track which stage of stellar life is represented by a particular type of variable stars. Let's see what major pulsating variable star types are and learn about their place on the H-R diagram. This approach is very useful, as it also allows to make a decision about a variability type of a star for which the properties are known partially. The Hertzsprung-Russell diagram shows a group of stars in different stages of their evolution. It is a plot showing a relationship between luminosity (or abso- lute magnitude) and stars' surface temperature (or spectral type). The bottom scale is ranging from high-temperature blue-white stars (left side of the diagram) to low-temperature red stars (right side). The position of a star on the diagram provides information about its present stage and its mass. Stars that burn hydrogen into helium lie on the diagonal branch, the so-called main sequence. In this article intrinsically pulsating variables are covered, showing their place on the H-R diagram. Pulsating variable stars form a broad and diverse class of objects showing the changes in brightness over a wide range of periods and magnitudes. Pulsations are generally split into two types: radial and non-radial. Radial pulsations mean the entire star expands and shrinks as a whole, while non- radial ones correspond to expanding of one part of a star and shrinking the other. Since the H-R diagram represents the color-luminosity relation, it is fairly easy to identify not only the effective temperature Intrinsic variable types on the Hertzsprung–Russell and absolute magnitude of stars, but the evolutionary diagram. -

THE EUROWET CO-OPERATION J.-E. Solheim
Baltic Astronomy, vol. 7, 319-328, 1998. THE EUROWET CO-OPERATION J.-E. Solheim Department of Physics, University of Troms0, N-9037 Troms0, Norway Received March 1, 1998. Abstract. The WET groups in Europe co-operate on many levels. With a grant from the European Union, instrument development, joint observing campaigns and some short-time support for young scientists have been possible. At the moment the grant has expired, but instrument development continues with own funds, concentrating on the development of high-speed CCD photometers. Key words: observing campaigns - observing networks - instru- mentation: CCD photometers 1. INTRODUCTION The aim of WET is to engage astronomers from all continents in joint observing campaigns and to develop instruments and cre- ate tools for analysing the data acquired. In principle, any sub- organizations should not be necessary. Our slogan is that the Whole Earth is our telescope, and we should work ideally as one unit. How- ever, in order to apply for funding related to the geographically lim- ited area, we found it necessary to organise the European partners in WET. The result of this will be explained in the following. WET has not always been a world-wide co-operation. We must remember that the original idea behind WET was that it should be an instrument for Texas astronomers to observe their targets. Colleagues around the world should apply for observing time, and observers from Texas should bring their instruments, do the obser- vations and bring the data home for analysis. This did not work. It soon became obvious that it would be too expensive to travel all over the world from Texas for each campaign. -
