Re:IRAS 13373+0105
IRAS 13373+0105 (NGC 5257/5258).---This object is an interaction
between NGC 5257 and NGC 5258, separated by 1.3' (Vorontsov-Velyaminov
1959). From the position of the IRAS source, both galaxies probably
contribute to the IRAS source. A bridge between the two galaxies is
observed in the red continuum image but is not observed in the
H{alpha} image. The H{alpha} emission observed in NGC 5257 is located
in the tidal arms. One peak of H{alpha} emission is seen in NGC 5258
with a tail extending to the northwest. The southern tail of NGC 5258
is only observed in the red continuum image. From the flux ratios given
for NGC 5257 and NGC 5258 in Lui &Kennicutt (1995), these galaxies are
both classified as starbursts.
