Abstract :
2D Modelling the low surface brightness stellar host in BCDs: Comparison
with classical monodimensional ones.
In Blue Compact Dwarfs galaxies, the stellar and ionized gas emission from
the starburst overshines in the innermost part of the galaxy,
the low surface brightness (LSB) stellar component, so the study of this
stellar host relies enterely on the outer regions.
Here, as a part of a larger program, we fitted the LSB component with a
Sersic law using the 2D optical and NIR images after masking out the starburst with
the help of our H_alpha images and color maps. We compare
the sersic parameters determined with this method and previous fits of
averaged 1D profiles for two typical BCDs of our sample, Haro2 and Haro3.
