Research activities of the Centre in large involve student participation at various motivational grant programmes as well as organisation of informal seminars and workshops. Students are encouraged to participate at international conferences and to get involved in solving research grants. For instance, students and researchers of the Centre were involved in the following selected activities in the period 2014-2017:
Pavel Bakala; Thin accretion disks of neutron stars influenced by the relativistic Poynting-Robertson effect

Starting Activities
During the summer 2014 we started very comprehensive activities utilising, above all, the support in the frame of projects SGS/11/2013 ‘Analysis and Modelling of Astrophysical Observations of Relativistic Compact Stars’ and OPVK CZ.1.07/2.2.00/28.0271 ‘Intensification of International, Interdisciplinary and Intersectoral Attitudes while Studying’. In cooperation with the experts from the Institute of Astronomy (Prague) and experts from several EU countries we organised, together with the research Centre of Theoretical Physics and Astrophysics, more than ten workshops focused primarily on involving the students in the active research work within the centres.
Due to the Centre’s considerable orientation to international cooperation, an important part of making the involvement of students more attractive as well as efficient is the possibility for the students to take part in placements or study visits abroad. In 2014 there were two monthly study visits of a doctorand student Mgr. Urbancova at a prestigious American institution Oak Ridge National Laboratory.
There also were several short placements abroad. Among others. doctoral student Mgr. Goluchova visited a leading Polish institution CAMK. For 2015 three IGS projects have been prepared, these support cooperation with institutions abroad, where students can get directly involved.
Last but not least, the programme of the Centre’s activities also takes into account participation of excellent students from abroad both in the form of external cooperation with the SU students and directly in the frame of doctorand studies. Currently a half year stay is being prepared for a doctorand Vitorrio de Falco from International Space Science Institute in Bern, Switzerland, which will focus on the problems of radiation from the vicinity of black holes and the mission of LOFT observatory.
