... Seminar archive . ... The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ... On the other hand, there have been numerous claims in recent years that the disc extends to the ISCO in the hard state. ...

Post-Asymptotic Giant Branch (post-AGB) stars bear signatures of the entire chemical and morphological changes that occur prior to and during the AGB phase of evolution. ... In this talk, I will present two important outcomes of this survey. Firstly, this survey resulted in a well characterised sample of binary and single post-AGB stars. ... However, some objects show peculiar chemical signatures which do not correspond to the accepted single/binary star evolution and nucleosynthesis. ...
