Re: [vsnet-chat 2600] TmzV85 Eclipse Elements? > Has anyone actually posted eclipse elements for this object as yet, and > it's just that I've missed it? In vsnet-alert 4048, eclipse predictions are given. http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/alert4000/msg00048.html We have not yet presented an eqation like Epoch + P * E, in order to avoid excessive extrapolations. We may be able to refine the element after finishing the entire run (and probably some quiscence runs). > Memory tells me that UGSU stars are likely to have slightly different > elements per outburst. Is memory right, and is this related to the disk > precession models? Slightly different "superhump" clocks per outburst by the mechanism quoted. Eclipses are more regular but have finite varying O-C's, which are caused by assymmetric disk light. By the way, TmzV85 has made the (long expected and sought) first-ever simutaneous discovery of eclipses and superhumps in the history of CVs. The other deeply eclipsing SU UMa stars are Z Cha (eclipse discovered in quiescence), OY Car (eclipse discovered during the rise to a normal outburst, cf. IAUC 3357), HT Cas, DV UMa, V2051 Oph (eclipse discovered in quiescence). Regards, Taichi Kato
