摘要:

2 MASS J 09440940 -5617117在2007年被确认为激变变星。在这篇文章中,我们提出了在Rc波段使用0.6米望远镜在Observatorio do Pico dos Dias/巴西。完整的光变曲线证实了深食的存在。我们得到轨道周期为0.1879340(5)d。日食的宽度为0.112 +- 0.003轨道周期。

英文摘要:

2MASS J09440940-5617117 was identified as a cataclysmic variable in 2007 by its spectrum. In this article we present optical differential photometry in the Rc band obtained using the 0.6-m telescope at Observatorio do Pico dos Dias/Brazil. The complete light curves confirm the presence of a deep eclipse. We derive an orbital period of 0.1879340(5) d. The eclipse has a width of 0.112 +- 0.003 orbital cycles.
