Analysis of Galactic late-type O dwarfs: more constraints on the weak wind problem (2009)
Marcolino, W. L. F., Martins, F., Hillier, D. J., Lanz, T., Escolano, C.
We have investigated the stellar and wind properties of a sample of five late-type O dwarfs in order to address the weak wind problem. A grid of TLUSTY models was used to obtain the stellar...
The weak magnetic field of the O9.7 supergiant zeta Orionis A (2008)
Martins, F., Escolano, C., Marcolino, W., Lanz, T., ...
We report here the detection of a weak magnetic field of 50 - 100 G on the O9.7 supergiant zeta Ori A, using spectropolarimetric observations obtained with NARVAL at the 2m Telescope Bernard Lyot...
