Observations of TT Ari requested in support of MOST observations
Abstract:
Dr. Nikolaus Vogt (Universidad de Valparaiso, Chile) has requested photometry and spectroscopy of the novalike (VY Scl subtype) cataclysmic variable TT Ari in support of upcoming observations with the Canadian Microvariability and Oscillations of Stars (MOST) satellite. The observations are being carried out to study superhump behavior, which is still not well understood despite the amount of research done in all classes of cataclysmic variables. MOST will observe TT Ari between 2012 September 13 and October 20.
Justification:
To study superhump behavior in TT Ari, given its characteristic of exhibiting both positive and negative superhumps. The study aims to detect significant superhump period variations, periodic signals, and quasi-periodic oscillations (QPOs), and to analyze the pronounced flickering observed in TT Ari. These observations will help in understanding the time-dependent behavior of accretion disks in cataclysmic variables.
