摘要：
We present a detailed model for the magnetic field of the chemically peculiar star HD 119419 consistent with five different kinds of observational constraint: mean longitudinal field, crossover, mean quadratic field, projected equatorial velocity and stellar radius. The stellar surface presents a complex magnetic structure originated by a 17 kG dipole superposed to a 48 kG quadrupole, and includes patches characterised by a field strength up to 50 kG.
