The Symbiotic Phenomenon
Symbiotic stars were identified spectroscopically as M giants with a very strong He II 4686 emission line. After five decades of study by many astronomers, the first internatioinal meetings devoted to symbiotics were held at the University of Colorado (Boulder) and at the Haute Provence Observatory during the Summer of 1981. These conferences emphasized exciting new results obtained by modern satellite (EINSTEIN, IUE) and ground-based observatories. Although the vast majority of the participants were already fairly sure that symbiotics are almost certainly interacting binary systems, and not extremely peculiar single stars, it was not clear exactly which types of physical processes were need...
Cataclysmic Variables
Cataclysmic Variables (CVs) are well furnished laboratories in which one can investigate a number of important physical processes. These processes include: thermonuclear reactions, nebular physics, winds, mass accretion phenomena on compact objects, magnetohydrodynamics, plasmas, thermal and non thermal radiative processes, relativistic phenomena, dust forma tion, etc . . In the recent year the most exciting development in our opinion was that the small, cold and invisible secondary components of CV s were found to be the prime motors for the evolution of close binary systems, disclosing new scenarios for research. All branches of astronomy and as trophysics often take advantage of the new i...

Proceedings volume for researchers and graduate students of astronomy, covering the most exciting science and key ELT projects.
Postępy 2/1981
Jeden z archiwalnych numerów "Postępów Astronomii". Było to czasopismo naukowe, a później popularnonaukowe na temat astronomii i badań kosmosu, wydawane w latach 1953-1997 przez Polskie Towarzystwo Astronomiczne (PTA). W roku 1998 roku nastąpiło połączenie z czasopismem "Urania" i od tamtej pory ukazuje się jako "Urania - Postępy Astronomii". Obecnie "Urania - Postępy Astronomii" to nowoczesny i elegancki magazyn dla wszystkich miłośników kosmosu, wydawany wspólnie przez Polskie Towarzystwo Astronomiczne, zrzeszające zawodowych astronomów oraz Polskie Towarzystwo Miłośników Astronomii (PTMA), którego członkami są pasjonaci kosmosu. Redakcja "Uranii - Postępów Astr...
Stellar Jets and Bipolar Outflows
In the last few years great improvements in the study of stellar jets and bipolar outflows have been achieved, both observationally and theoretically. High resolution observations at various frequencies (radio, IR, optical and X-ray) of these features in different types of objects have shown a large variety of morphologies at all scales often revealing contrasting symmetries which do not allow straightforward kinematic interpretations valid for all cases. In particular, at present, it seems very difficult to give a statistical definition of what the "standard properties" of jets and bipolar outflows are. On the theoretical side, the identification of physical processes capable of producing t...

Stellar Astrophysics with the World's Largest Telescopes
The book reviews the most timely and interesting problems of stellar astrophysics, particularly those suitable for studies with the world's largest telescopes, and it can serve as an introduction to such studies. In particular it gives a comprehensive presentation of state-of-the-art research in stellar and planetary system formation, extra-solar planets, final stages of single and binary stellar evolution, and stellar populations in the Local Group of Galaxies, including observational techniques and technologies applicable to those important fields. The book also presents the most important unresolved problems of stellar astrophysics, intended to help identify directions for future research.
