Guidelines
V teoretické části práce se autorka bude zabývat teorií vzniku nov v galaxiích a obecně využitím nov jako indikátoru vzdálenosti v kosmologii.
V praktické části se diplomant seznámí s objevováním a CCD fotometrií nov v blízkých galaxiích, např. v galaxii M81.
Cílem práce pak bude porovnání, statistický přehled a kritické zhodnocení populace nov ve vybraných galaxiích.

Preliminary scope of work in English
Novae possess a number of attributes that make them potentially valuable standard candles. They are luminous (approaching M_v = -10 mag)
and easy to recognize. Because they belong to an old stellar population, they are found predominantly in ellipticals and the bulges of spirals;
such environments are relatively dust-free and photometrically smooth, so that observations of novae beyond the Local Group are simpler
and easier to interpret than observations of Cepheids. The available evidence suggests that observations of novae are not strongly affected
by metallicity effects. Finally, the calibration of novae as standard candles possesses relatively low intrinsic scatter and is well
understood theoretically.
