VSX J074727 .6+065050：小犬座的一颗新的WZ人马座恒星
VSX J074727.6+065050: a new WZ Sagittae star in Canis minor
摘要：
我们提出的第一个报告的矮新星VSX J074727.6+065050在2008年1月和2月的超爆发测光。在最亮的时候，这颗恒星的星等达到了11.4等，随后在0.09等/日的水平上缓慢下降了19天，这对应于平台期。然后在1.66等/日迅速下降到16.6等的暂时最小值，并在那里停留了2到3天，之后有6次显着的回波爆发，然后在大约19.5等时逐渐变暗。总的爆发幅度至少为8级，持续时间超过80天。在平台期，我们观察到Psh = 0.06070（6）d的常见超峰，但随着平台期的结束和快速下降的开始，周期增加到Psh = 0.06151（5）d。这对应于P^dot = +4.4（9）x 10-5的连续周期变化。在回波爆发期间，存在一个Psh = 0.06088（49）d的超峰区。证据是一致的恒星是一个成员的WZ Sge家族的矮新星。
英文摘要：
We present photometry of the first reported superoutburst of the dwarf nova VSX J074727.6+065050 during 2008 January and February. At its brightest the star reached magnitude 11.4 and this was followed by a slow decline at 0.09 mag/d for 19 days, corresponding to the plateau phase. There was then a rapid decline at 1.66 mag/d to a temporary minimum at magnitude 16.6 where it stayed for 2 to 3 days after which there were six remarkable echo outbursts before the star gradually faded back towards quiescence at ~magnitude 19.5. The overall outburst amplitude was at least 8 magnitudes and it lasted more than 80 days. During the plateau phase we observed common superhumps with Psh = 0.06070(6) d, but the period increased to Psh = 0.06151(5) d coinciding with the end of the plateau phase and the onset of the rapid decline. This corresponds to a continuous period change with P^dot = +4.4(9) x 10-5. During the echo outbursts there was a superhump regime with Psh = 0.06088(49) d. Evidence is presented which is consistent with the star being a member of the WZ Sge family of dwarf novae.
