The effects of convective overshooting on naked helium stars: 《Research in Astronomy and Astrophysics》2016年第9期75-82,共8页Jing-Zhi Yan Chun-Hua Zhu Zhao-Jun Wang Guo-Liang Lü; supported by the Xinjiang Science Fund for Distinguished Young Scholars under Grant Nos. 2013721014 and 2014721015;the National Natural Science Foundation of China under Grant Nos. 11473024, 11363005 and 11163005; Using stellar evolutionary models, we investigate the effects of convective overshooting on naked helium stars. We find that a larger value of overshooting parameter δov results in a larger convective core, which pro...; 关键词：STARS evolution- stars interiors- stars fundamental parameters
