A short and sudden increase of the magnetic field strength and the accompanying spectral variability in the O9.7V star HD54879
S. Hubrig, M. Kueker, S. P. Jarvinen +4
Only eleven O-type stars have been confirmed to possess large-scale organized magnetic fields. The presence of a -600G longitudinal magnetic field in the O9.7V star HD54879 with a…
