英文摘要A 70 M-circle dot black hole (BH) was discovered in the Milky Way disk in a long-period detached binary system (LB-1) with a high-metallicity 8 M-circle dot B star companion. Current consensus on the formation of BHs from high-metallicity stars limits the BH mass to be below 20 M-circle dot due to strong mass loss in stellar winds. Using analytic evolutionary formulae, we show that the formation of a 70 M-circle dot BH in a high-metallicity environment is possible if wind massloss rates are reduced by factor of five. As observations indicate, a fraction of massive stars have surface magnetic fields that may quench the wind mass-loss, independently of stellar mass and metallicity. We confirm such a scenario with detailed stellar evolution models. A nonrotating 85 M-circle dot star model at Z = 0.014 with decreased winds ends up as a 71 M-circle dot ends up as a 71 M-circle dot star prior to core collapse with a 32 M-circle dot He core and a 28 M-circle dot CO core. Such a star avoids star prior to core collapse with a 32 M-circle dot He core and a 28 M-circle dot CO core. Such a star avoids the pair-instability pulsation supernova mass loss that severely limits BH mass and may form a similar to 70 M-circle dot BH in the direct collapse. Stars that can form 70 M-circle dot BHs at high Z expand to significant sizes, with radii of R greater than or similar to 600 R-circle dot, however, exceeding the size of the LB-1 orbit. Therefore, we can explain the formation of BHs up to 70 M-circle dot at high metallicity and this result is valid whether or not LB-1 hosts a massive BH. However, if LB-1 hosts a massive BH we are unable to explain how such a binary star system could have formed without invoking some exotic scenarios.
