Observations of the first confirmed superoutburst of SDSS J080434.20+510349.2 in 2006 March
摘要:
在2006年3月期间,首次确认的矮新星SDSS J080434.20+510349.2的超爆发是使用未过滤的CCD测光观测到的。时间序列测光显示超级驼峰的周期为0.0597 +/- 0.0011 d,振幅为0.2等,从而独立建立了它的UGSU分类。在从13.1的峰值震级下降后,至少观察到两次再亮事件。证据是一致的明星是UGWZ子类的成员。
英文摘要:
During 2006 March the first confirmed superoutburst of the dwarf nova SDSS J080434.20+510349.2 was observed using unfiltered CCD photometry. Time-series photometry revealed superhumps with a period of 0.0597 +/- 0.0011 d and an amplitude of 0.2 magnitude, thereby independently establishing its UGSU classification. Following the decline from a peak magnitude of 13.1, at least two rebrightening events were observed. Evidence is presented which is consistent with the star being a member of the UGWZ sub-class.
