Abstract:
The observational data analysis indicates that the star is enveloped into a nebula considerably stretched along the equatorial plane. Vega is a star with B9.5IV-V characteristics with Te=10.105±230 K and R=2.69±0.25 R⊙. The cover deforms energy distribution in Vega spectrum. As a result, the energy from with distribution corresponding to an A0V star is imitated in the direction towards the observer. © 1990 Kluwer Academic Publishers.
