鲸鱼座WW的第一次历史性停滞
The First Historical Standstill of WW Ceti
摘要：
Z Cam矮新星与其他矮新星的区别在于它们的长期光学光变曲线中出现了所谓的“静止”。之前曾有人提出，WW Cet可能是一颗Z Cam型矮新星，但这种分类后来被排除，基于它的长期光变曲线行为。40年的历史数据显示，WW Cet没有停滞的证据。因此，鲸鱼座WW在变星总表（GCVS）和国际变星索引（VSX）中被归类为UG型矮新星。从2010年观测季节开始，Cet WW被观测到处于停滞状态，或多或少地保持在12等范围内。基于这第一次，鲸鱼座WW的历史停滞，我们得出结论，它确实是一个真正的成员Z凸轮类矮新星。
英文摘要：
Z Cam dwarf novae are distinguished from other dwarf novae based on the appearance of so called 'standstills' in their long-term optical light curves. It has been suggested previously that WW Cet might be a Z Cam type dwarf nova, but this classification was subsequently ruled out, based on its long-term light curve behavior. Forty years of historical data for WW Cet has shown no evidence of standstills. WW Ceti is therefore classified as a UG type dwarf nova in the General Catalog of Variable Stars (GCVS) and the International Variable Star Index (VSX). Beginning in the 2010 observing season, WW Cet has been observed to be in a standstill, remaining more or less steady in the 12th magnitude range. Based on this first ever, historical standstill of WW Ceti, we conclude that it is indeed a bona fide member of the Z Cam class of dwarf novae.
