The API colloquia are weekly meetings where people give a 45 minute
overview of their work. Afterwards there is time for discussion.
At the end of each month the colloquia are jointly held with

Master colloquium: The bursting behaviour of AX J1745.7-2901
Sjors Broersen — UvA
In this talk, the X-ray bursting behaviour of the faint, transient, X-ray binary AX J1745.6-2901 is reported. This dipping and eclipsing source was first observed in 1996 by Maeda and collaborators and has shown several periods of activity since then. We have screened all XMM Newton observations in which this source was in the field of view.

Marten van Kerkwijk — University of Toronto
