In my talk I will discuss the detection and dynamical properties of circumbinary extrasolar planetary systems. I will pay special attention to the detection of circumbinary companions using the light-travel time effect and highlight some problems of proposed systems discovered from ground-based observations. In addition, I will briefly review the latest discoveries of circumbinary planets detected by the Kepler space telescope.
Only two Nicolaus Copernicus University PhD students received ETIUDA 2 grants in ST (science and technology), announced at the end of June 2014. Both Jan Ostrowski and Tomasz Kazimierczak of the Toruń Centre for Astronomy were awarded ETIUDA 2 grants to work on particular aspects of their doctoral projects in relativistic cosmology. The grants will help them consult with Thomas Buchert and numerical galaxy formation specialists at CRAL at the University of Lyon.
