Scientific paper

We present mid-infrared observations of Mrk 171, a system of at least two interacting galaxies, which has been observed with the ISOCAM camera in the spectral range 5-16 μm. The comparison of the mid-infrared morphology with that at shorter wavelengths, as well as the overall variation of the spectral energy distribution of the different components leads us to conclude that i) the system is the result of the interaction of ONLY two galaxies, ii) there is no evidence of an active galactic nucleus in the system and iii) intense star formation occurs outside the nucleus of NGC 3690. Mid-infrared observations appear then to be a powerful tool to probe deeply obscured regions harboring either star forming regions or AGNs.
