Scientific paper

We have used the European Southern Observatory (ESO) 10 micrometer camera, TIMMI, to image with a very high angular resolution (PFoV: 0.3 sec; full width at half maximum (FWHM): 0.9 sec) several main-sequence star disk candidates. Information on the beta-Pictoris dust disk has been obtained in a region largely inaccessible to previous observations: 0-80 AU, with a resolution of about 5 AU after deconvolution. Another promising target for 10 micrometer imaging, 51 Ophiuchi, appears point-like.
