Re: [vsnet-chat 3422] Re: Permanent Superhumpers... Stan is probably right in the origin of the term "superhump", then what about "superoutburst" or "SU UMa-type" ? Because of the presence of the northern protype, some of these terms may have been US coined. Regarding "permanent superhumpers", I thought that the term was first used by Y. Osaki in his dwarf nova unification theory. [Am I correct?] By the way, "permanet superhumpers" are often abbreviated as "PS", just as SU for SU UMa stars. Some people is called to have invented a new interpretation of PS as "permanent student", from an analogy that CV represents curriculum vitae. Regards, Taichi Kato
