Researchers obtain special photometric behaviors of novae-like system and confirm evidence of disk wind

Ph.D. student Fang Xiaohui, and Prof. Qian Shengbang from Yunnan Observatories of the Chinese Academy of Sciences and collaborators analyzed the long-term photometric data of the nova-like SW Sextantis (SW Sex), and found that the light variation of this object shows a possible quasi-periodic oscillation with the time-scale of about ten years. Combined with the change of the orbital period, they inferred that there is a very strong wind in the system. The study was published in The Astrophysical...
