21 Cataclysmic variables to be observed by William Herschel Telescope
Active Dates: Dec. 14, 2016 – Dec. 16, 2016
Abstract:
Roque Ruiz-Carmona (Ph.D. candidate, Institute of Mathematics, Astrophysics and Particle Physics, Radboud University Nijmegen, The Netherlands) has requested AAVSO assistance with his campaign to observe a set of 21 cataclysmic variables (CVs) with the William Herschel Telescope (WHT) at La Palma on 2016 December 16. This campaign is essentially identical in format to the ones successfully carried out by the AAVSO on his behalf in 2015 and in May 2016.
Justification:
To investigate the hypothesis that spiral density waves can only be detectable in high inclination systems and that the luminosity of the disk in outburst outshines the spiral pattern for the rest of the system. The sample of CVs to be monitored contains only eclipsing systems.
