UBVRI surface photometry and long-slit spectrophotometric observations
are used to investigate the evolutionary status and put constraints o
n the age of the underlying stellar population of the eastern componen
t of a nearby pair of dwarf galaxies, the blue compact dwarf galaxy SE
S 0335-052E. We show that ionized gas emission extending out to distan
ces greater than or similar to 1 kpc from the central complex of super
-star clusters (SSC) can significantly influence the observed colour d
istribution of the underlying component. After correction for the latt
er effect, we find that the intrinsic colours of the underlying compon
ent in SBS 0335-052B are consistent with those of a stellar population
not older than 100 Myr, so that the BCD is truly a young galaxy.
