VLTI observations of Orion Belt stars I. ε Orionis.
OPLISTILOVA A., BROZ M., HUMMEL C.A., HARMANEC P. and BARLOW B.N.
Abstract (from CDS):
Massive stars play a decisive role in the evolution of the Universe. They are the primary sources of ionising radiation, generating strong stellar winds that affect the interstellar medium. They ultimately end their lives as supernovae, ejecting synthesised, r-process elements.
