Centauri : Helium Dwarf Nova Mimicking a WZ Sge - Type
We observed the long-term behavior of the helium dwarf nova V803 Cen, and clarified the existence of at least two distinct states (a state with 77-d supercycles and a standstill-like state) that interchangeably appeared with a time-scale of 1–2 yr. We also conducted a time-resolved CCD photometry campaign during the bright outburst in 2003 June. The overall appearance of the outburst closely re...

متن کاملPhotometric Studies of a WZ Sge-Type Dwarf Nova Candidate,ASAS160048-4846.2
We report on our time-resolved CCD photometry during the 2005 June superoutburst of a WZ Sgetype dwarf nova candidate, ASAS 160048-4846.2. The ordinary superhumps underwent a complex evolution during the superoutburst. The superhump amplitude experienced a regrowth, and had two peaks. The superhump period decreased when the superhump amplitude reached to the first maximum, successively graduall...
متن کاملLate Superhumps in WZ Sge-Type Dwarf Novae
We report on the detection of very stable modulations with periods unexpectedly (∼0.5 %) longer than superhump periods during the slowly fading stage of WZ Sge-type superoutbursts in three systems, GW Lib, V455 And and WZ Sge. These periods are naturally explained by assuming that these modulations are superhumps arising from matter near the tidal truncation radius. This finding provides an add...
متن کاملWZ Sagittae - an old dwarf nova
We model the evolution of the accretion disk of WZ Sagittae during the long quiescence. We find that the large amount of mass in the disk derived from the outburst luminosity is a severe constraint and demands values of αc ≈ 0.001 in contradiction to some recent suggestions. We include in our computations the formation of an inner disk hole and the growth of the disk due to redistribution of an...
