Descripción
A search for star-forming objects belonging to tidal tails has been
carried out in a sample of deep Hα images of 16 compact groups of
galaxies. A total of 36 objects with Hα luminosities greater than
1038 ergs s-1 has been detected in five groups.
The fraction of the total Hα luminosity of their respective parent
galaxies shown by the tidal objects is always below 5% except for the
tidal features of Hickson compact group 95, whose Hα luminosity
amounts to 65% of the total luminosity. Out of these 36 objects, nine
star-forming tidal dwarf galaxy candidates finally have been identified
on the basis of their projected distances to the nuclei of the parent
galaxies and their total Hα luminosities. Overall, the observed
properties of the candidates resemble those previously reported for the
so-called tidal dwarf galaxies.
