The evolution of BD+60°2522: with mass loss and overshooting

The ionizing star BD+60°2522 is known as the central star of Bubble Nebulae NGC 7635--wind-blown bubble created by the interaction of the stellar wind of BD+60°2522 (O6.5 IIIef, V=8.7 mag, mass loss rate 10^sup -5.76^ M ^sub ^/year) with the ambient interstellar medium. From the evolutionary calcula...

Summary:The ionizing star BD+60°2522 is known as the central star of Bubble Nebulae NGC 7635--wind-blown bubble created by the interaction of the stellar wind of BD+60°2522 (O6.5 IIIef, V=8.7 mag, mass loss rate 10^sup -5.76^ M ^sub ^/year) with the ambient interstellar medium. From the evolutionary calculations for the star with mass loss and overshooting, we find that the initial mass of the star is 60M ^sub ^, its present age is 2.5×10^sup 6^ years, and the present mass is 45M ^sub ^.
