O článku:

We announce a study of photometric behaviour of TT Ari in the time interval between 2004 and 2013, including its last low state that occurred in 2009 — 2010. We used data of the VSNET Collaboration, AAVSO and ASAS databases. We found that negative superhumps in TT Ari take place only if the brightness of the object is larger than 11.5 mag. Here we also claim the first detection of co-existense of negative and positive superhumps in TT Ari and present a refined orbital ephemeris.
