Students who attend this two-weeks workshop will learn how to preper and performe spectroscopic and photometric observations using instrumentation at the Ondřejov observatory. The focuse will be on spectroscopic and lightcurve observations of eclipsing hot subdwarf stars with cool, low-mass companions in different filters. Those objects are especially interesting as the companion can be a M dwarf or even a substellar companion as a brown dwarf or massive planet.
The students will be teached how to reduce photometric and spectroscopic data. For all observations an analysis of the lightcurve using the lightcurve fit program LCURVE will be performed to determine absolute parameters (mass, radius) and orbital parameters as separation or period of both stars and determine the nature of the companion. For reduction of spectroscopic data the IRAF program will be used.
