Researchers reveal rapid mass transfer between twin components in hierarchical triple system
In a study published in Monthly Notices of the Royal Astronomical Society, Dr. Zhao Ergang and Prof. Qian Shengbang from Yunnan Observatories of the Chinese Academy of Sciences revealed rapid mass transfer between the two twin components in the eclipsing binary system GK Cepheus (GK Cep), suggesting that GK Cep is a key target to understand the mass transfer during binary evolution. They found that this system contains a solar-type stellar component expect the eclipsing binary.
