摘要
Ultra-magnetized white dwarfs with interior fields up to 1018 G have recently been proposed to have a critical mass limit Mmax ≈ 2.58 M⊙, which surpasses the traditional Chandrasekhar limit Mch ≈ 1.44M⊙. We show that several stability criteria and fundamental physical aspects that take place when huge magnetic fields and high densities are present have been neglected in the determination of such a new mass limit for white dwarfs, invalidating that result.
