- Timetable of Seminar Groups:
- Prerequisites
- Graduation of first two the terms of physics and the course Common astronomy.
- Course Enrolment Limitations
- The course is offered to students of any study field.
- Course objectives
- 2 hours of classical readings weekly + 1 hour of exercises. Students will acknowledge here with the basic types of astronomical observations and with basic astronomical instruments. The course is an immediate continuation of the course "Common astronomy".
- Learning outcomes
- Student will be able completing the course:
- explain refrection and atmospheric phenomena;
- distinguis individual mounts and kinds of telescopes;
- apply different observational methods;
- used different derectors; - Syllabus
- Earth atmosphere and its influence on the observations. Structure and composition of the atmosphere. Circulation in the atmosphere. Dust particles. Refraction, scintillation, seeing. Heaven's sphere. Sky light. The transmission of the earth atmosphere. Extinction and its measurement. The moments of rises, sets and culminations of celestial bodies. Twilight, the visibility of satellites.
- Stellar catalogues, atlases and annual ephemerides. Sky – naming of stars and constellations. Stellar catalogues. Ephemerides of the Sun, Moon, planets and their moons. Astronomical manual.
- Astrophysical observational instruments. Radiation. Transparency of the atmosphere in different parts of the electromagnetic spectrum. The ground and cosmic astronomy. The human eye, its structure, astronomical observations done by naked eyes – advantages, limitations.
- Optical telescopes. Types of optical systems. Refractors, reflectors. Mountings. The biggest telescopes in the world. Adaptive optics. Telescopes on the satellites HST, Hipparcos).
- Detectors of the radiation. Photometry. Photographic emulsion – its properties, the density curve. Photoeffect. Photomultiplier. Photoelectric photometry and its methods. Photometric systems. Photometric processing. CCD elements – the principle. CCD observations specifics. UV and IR photometry.
- Spectroscopy Types of spectrographs and their astrophysical applications. The basic spectroscopic concepts (continuum, line profile, equivalent width, radial velocity). The processing of spectroscopic observations. What can we reproach from a stellar spectrum – a review.
- Radioastronomy – a reviews. Antennas, radiotelescopes. Point-like and areal radio sources, continuous and discrete radiation. Interferometry, aperture synthesis VLBI, Measurements in mm and sub mm region.
- Ultraviolet, X-ray and gamma-astronomy. Detectors, objectives, telescopes. Cosmic radiation, neutrinos, gravitational waves – their detection.

- Teaching methods
- 2 hours classical lectures + 1 hour class exercises, consultations, all is ended by the oral examination
- Assessment methods
- 2 hours lecture, 1 hour class exercises. Potential for examination is credit for active participation on class exercises. In case of interest will be consultation. During the examination student draws lots 2 question and has 30 minutes for preparation, student may use own helps including lecture notes. Examination is 30 minutes long, it is individual and relatively hard, aim of examination is determine if student can understand of subject matter.
