We propose to use the ISOCAM instrument to obtain mid-infrared spectral imaging data for the bulges of 4 early-type spiral galaxies with LINER nuclei. These data will be complementary to our high spatial resolution 50 and 100 micron observations of these bulges, obtained with the Kuiper Airborne Observatory. Our KAO observations show that these bulges are quite luminous in the far-infrared, and the far-infrared emitting regions are quite extended (FWHM = 1 kpc = 30"). Our goals in the proposed mid-infrared studies are: 1) to determine the mid-infrared continuum distribution across these bulges (is it similar to that in the far-infrared? Can we identify morphological features, such as bars and circumnuclear rings, which are unresolved in the far-infrared?). 2) to determine the infrared spectral energy distribution as a function of position in these bulges (are there strong mid-infrared color temperature gradients across the bulges? are emission lines present? Are silicate absorption lines seen?). 3) to determine the distribution of very small dust grains in these bulges, via the `unidentified' mid-infrared emission lines (are the emission features non-existent near the LINER nucleus, and bright elsewhere in the bulge? or the reverse? is the distribution of small grains similar to that of the far-infrared continuum?). 4) to compare the mid-infrared properties of these relatively quiescent bulges to those containing starbursts and Seyfert nuclei.
