ST Chamaeleontis和BP Coronae Australis：两颗南矮星新星被确认为Z Cam星
ST Chamaeleontis and BP Coronae Australis: Two Southern Dwarf Novae Confirmed as Z Cam Stars
摘要：
鹿豹座Z星（Z Cam）是矮新星的一个子集，其特征是出现静止，相对恒定的亮度周期比最大亮度暗一到一个半星等。作为正在进行的观测活动Z Campaign的一部分，作者将注意力集中在南半球的几个Z Cam嫌疑人身上。在2013年发现了两颗恒星，BP Coronae Australis和ST Chamaeleontis表现出静止行为，从而确认它们是Z Cam型系统。这为19个确认的Z Cams增加了两个真正的成员，使总数达到21个。
英文摘要：
Z Camelopardalis (Z Cam) stars are a subset of dwarf novae distinguished by the occurrence of standstills, periods of relative constant brightness one to one and a half magnitudes fainter than maximum brightness. As part of an ongoing observing campaign, the Z CamPaign, the authors focused attention on several Z Cam suspects in the southern hemisphere. Two stars, BP Coronae Australis and ST Chamaeleontis were found to exhibit standstill behavior in 2013, thus confirming them as Z Cam type systems. This adds two more bona fide members to the 19 confirmed Z Cams, bringing the total to 21.
