Abstract:
We investigate the massive star population of NGC 6822 with
ground-based UBV photometry covering the whole of the galaxy and HST
WFPC2 photometry with filters F255W, F336W, F439W, and F555W of two
fields containing very rich and crowded OB associations. The four-band
WFPC2 photometry is used to derive Teff and E(B-V). H-R diagrams are
constructed for the OB associations included in our fields. These show
that 10Myr old populations are present in OB 9 and OB 6, while more
recent star formation have occurred in OB 8, OB 13, OB 15, and OB 7.
Two particularly interesting H II regions, Hubble V and Hubble X, are
included in our fields. The luminous massive stars that power these
bright H II regions (Halpha luminosity several times that of the
Orion nebula), could be resolved even in their dense cores thanks to
the HST spatial resolution. Our data reveal very young (a few million
years), apparently coeval populations, with several massive star
candidates.
