X-ray and UV emission of the ultrashort-period, low-mass eclipsing binary system BX Tri
V. Perdelwitz, S. Czesla, J. Robrade +2
Close binary systems provide an excellent tool to determine stellar parameters such as radii and masses with a high degree of precision. Due to the high rotational velocities, most…
A systematic approach to determining the properties of an iodine absorption cell for high-precision radial velocity measurements
V. Perdelwitz, P. Huke
Absorption cells filled with diatomic iodine are frequently employed as wavelength reference for high-precision stellar radial velocity determination due their long-term stability…
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…
