Probing the weak wind phenomenon in Galactic O-type giants

E. S. G. de Almeida, W. L. F. Marcolino, J. -C. Bouret +1

Analyses of Galactic late O dwarfs (O8-O9.5V) raised the `weak wind problem': spectroscopic mass loss rates ($\dot{M}$) are up to two orders of magnitude lower than the theoretical…
