Long-term variations in the X-ray activity of HR 1099
V. Perdelwitz, F. H. Navarrete, J. Zamponi +6
Although timing variations in close binary systems have been studied for a long time, their underlying causes are still unclear. A possible explanation is the so-called Applegate m…

A new approach to distant solar system object detection in large survey data sets
V. Perdelwitz, M. Völschow, H. M. Müller
The recently postulated existence of a giant ninth planet in our solar system has sparked search efforts for distant solar system objects (SSOs) both via new observations and archi…

The Applegate mechanism in Post-Common-Envelope Binaries: Investigating the role of rotation
F. H. Navarrete, D. R. G. Schleicher, J. Zamponi +1
Eclipsing time variations (ETVs) are observed in many close binary systems. In particular, for several post-common-envelope binaries (PCEBs) that consist of a white dwarf and a mai…
