ISO OBSERVATIONS OF WOLF-RAYET GALAXY HARO-3

Observations of the blue compact dwarf galaxy Hare 3 have been obtaine d with the ISOCAM and ISOPHOT instruments on the Infrared Space Observ atory (ISO). The PHT-S spectrum (6-12 mu m) is dominated by four emiss ion bands that are frequently attributed to polycyclic aromatic hydroc arbons (PAHs) and strong SIV emission. Two CAM filters, LW6 (7-8.5 mu m) and LW3 (12-18 mu m) were used to map the galaxy. The LW6 image is essentially a map of the galaxy in the 7.7 mu m PAH feature. The emiss ion in both maps is extended and matches very well a map of the H alph a emission. Both maps show coincident single peak emission and a spati al correspondence with the nuclear region of the galaxy and the bright est optical region, an off-axis starburst containing Wolf-Rayet stars. A ratio map of LW6/LW3 images shows two peaks on a ridge elongated al ong the optical axis of the galaxy.
