A new photometric study of the triple star system EF Draconis
《Research in Astronomy and Astrophysics》2012年第4期419-432,共14页Yuan-Gui Yang 
supported by the National Natural Science Foundation of China (Nos.10778707 and 11133007);Anhui Provincial Natural Science Foundation (No.1208085MA04);the Open Research Program (No.OP 201110) of the Key Laboratory for the Structure and Evolution of Celestial Objects of CAS
We present new charge-coupled device （CCD） photometry for the triple star EF Draconis, obtained in 2009 and 2011. Using the updated Wilson-Devinney program, the photometric solutions were deduced from two sets of li...

The ROSAT bright source 1RXS J201607.0+251645:an active Algol-type binary
《Research in Astronomy and Astrophysics》2009年第9期1035-1048,共14页Hua-Li Li Yuan-Gui Yang Wei Su Hui-Juan Wang Jian-Yan Wei 
Supported by the National Natural Science Foundation of China(Grant Nos.10778707 and 10473013)
1RXS J201607.0＋251645 is identified as an eclipsing binary. We present preliminary observations in the V band with the 0.6-m telescope for three years and extensive observations in the V and R bands with the 0.8-m te...
