... A light curve decomposition tool ( LFIT ) developed by Keith Horne and Tom Marsh and its application on HST-data of the eclipsing dwarf nova IP Peg will be presented. ... Our LFIT code decomposes time-resolved spectral data into N components with parameterized light curve shapes, solving for the spectra of each component. ... To apply this algorithm to the HST and UBVRI eclipses of IP Peg, we add an ellipsoidal light curve for the companion star, and a more detailed description of the bright spot. ...

... This is the truly fun part, observing molecular and atomic gas in star-forming regions with a variety of telescopes. Depending on the temperature and density of the gas, different observations are necessary to study the components of star-forming regions.
