Studies of the magnetic fields of Herbig Ae/Be (HAeBe) stars can aid in understanding how the magnetic fields of AB stars of intermediate mass are created and evolve. It has been shown that the magnetic fields and magnetic fluxes of HAeBe stars before they emerge on the main sequence are significantly lower than for their successors, main sequence AB stars. In order to explain this mystery, the effect of accretion on Herbig stars and their magnetic fields is studied. Evidence is found in favor of the assumption that in magnetic HAeBe stars with a higher rate of accretion the magnetic fields are lower on the average. However, since the accretion rates fall off exponentially with the age of a star, even if it should be confirmed, this effect cannot fully explain the discontinuous increase in the magnetic fields and magnetic fluxes when HAeBe stars enter the main sequence.

Herbig Ae / Be星的吸积和磁场
对Herbig Ae / Be(HAeBe)恒星的磁场的研究可以帮助理解中等质量AB恒星的磁场是如何产生和演化的。研究表明,HAeBe星在出现在主序列上之前的磁场和磁通量显着低于其后继主序列AB星。为了解释这个奥秘,研究了吸积对赫比格星及其磁场的影响。有证据表明,在具有较高吸积率的HAeBe磁性恒星中,磁场平均较低。但是,由于吸积率会随着恒星的年龄呈指数下降,因此即使应予以确认,
