VZ Lib: a contact binary in a ternary system [Observed: 2007-2009, 14 sessions]
Time series of this eclipsing contact binary are reported and times of minima (ToM) of the eclipses are measured. This system has a third component. From the O-C analysis of the observed ToM and of those in the literature, the orbital parameters of the third body can be derived: the orbital period is 34.8 yr and the inclination is 11.5 °.

CoRoT-1: observations of the exoplanet transits [Observed: 28 Dec 2008, 18, 21 Mar 2009]
Amateur observations of this transiting exoplanet are presented and are modelled with BinaryMaker3.

WASP-2: possible detection of the exoplanet transit [Observed: 5 Aug, 11 Oct 2008]
Amateur observations of this transiting exoplanet are presented and are modelled with BinaryMaker3.

UX Mon: time keeping and modelling of a binary [Observed: 13 Dec 2007, 11-16, 18 Feb, 8, 13, 14 March, 1, 4, 25, 29]
Time series of this eclipsing binary system with extra variability are presented. The O-C analysis suggests the presence of a third star. The observations are modelled with BinaryMaker3 and parameters of the system are derived.

WX Eri / V1241 Tau: an eclipsing semi-detached binary system [Observed: 15 Oct, 29, 30 Nov, 13, 16 Dec 2007, 1, 23 Jan 2008]
Light curves of this eclipsing, semi-detached binary system with a period of 0.8d are presented and are modeled with BinaryMaker3. No evidence for a pulsating star in this system is found.

V1309 Ori: an eclipsing polar [Observed: 26 Dec 2006, 15 Feb, 7 Nov 2007]
A phase plot of this eclipsing polar is presented. I try to model it with BinaryMaker3.

BT Mon: eclipser with a hump [Observed: 26 Oct, 1 Nov, 24 Dec 2005, 19 Jan 2006]
Light curves of this cataclysmic star are presented. They show the eclipse with a large hump. They are modelled with BinaryMaker3.

SW Sex observation and BinaryMaker3 model [Observations: 10, 11, 14, 15 January 2005]
SW Sex is an accreting binary with deep, non symmetrical eclipses. The observations are modelled with the BinaryMaker3 program.
