Observational facilities:
Skalnaté Pleso Observatory and Stará Lesná Observatory - two 60 cm photometric
reflectors, a 50 cm reflector with a CCD camera.
Research activities:
- investigation of interacting binary and multiple systems, symbiotic
stars, novae and nova-like objects focused on physical processes
during phases of their activity, studies of their origin, structure,
evolution and physical conditions in the circumstellar environment,
- photometric detection of various manifestations of both regular and
semi-regular stellar variability, models' construction explaining the
behaviour of the systems,
- use of the IUE as well as HST databases for the spectroscopy
of interacting binaries and direct HST images to study expanding
envelopes of novae and symbiotic stars,
- spectroscopic investigation of chemically peculiar
star phenomena based on spectra from ESO, Mt. Stromlo, Nauchnyj,
Ondrejov, Rozhen and Zelenchuk observatories,
- study of the chemical composition and properties of the atmospheres of CP stars,
and the role of radiative diffusion of some species,
- search for possible relations between the orbital parameters of binaries
with Am components.
