weak-wind O-type star
setâre-ye O bâ bâd-e nezâr, ~ ~ ~ ~ kamzur
Fr.: étoile O de faible vent
A → main sequence → O star with low luminosity and surprisingly weak → stellar wind compared to "classical" dwarfs. The → mass loss rates are lower than 10-8 solar masses per year and the → modified wind momenta nearly 2 orders of magnitude smaller than that expected from wind models for typical O stars. Weak-wind O-type stars occur in both → metal-rich and → metal-poor environments. Their nature is not yet fully understood. same as → weak wind problem.
→ weak; → wind; → O-type star.
