Scientific paper

We present diffraction-limited images of the pre-main-sequence star LkHα 101 at a wavelength of 10 microns using the Lick 3 meter telescope. The point-spread function has FWHM ~ 0.8". Deconvolution algorithms can achieve a spatial resolution of ~ 0.4". We find the source is essentially unresolved even at these scales. The inferred size of the surrounding dust shell is comparable to the extent of the ionized stellar wind region measured with the VLA. These observations can be used to place interesting constraints on the size and distribution of dust grains.
