AR UMa photometry requested in support of XMM-Newton observations
Active Dates: May 5, 2023 – May 13, 2023
Abstract:
Dr. Axel Schwope (Leibniz-Institut für Astrophysik Potsdam) has requested the assistance of AAVSO observers in obtaining multicolor photometry on the magnetic cataclysmic variable AR UMa in support of observations with XMM-Newton.
Justification:
This object is of high interest because it is the magnetic CV with the highest magnetic field. X-ray observations are key to understanding the energy release in such a high field environment, but can be triggered only if the source is shown to be in a high state.
