Description
The region around the Herbig Ae/Be star LKH-alpha198 was imaged at 10
micrometer with the CAMIRAS camera at the Canada-France-Hawaii Telescope
and the Nordic Optical Telescope. We discovered a deeply embedded
companion 6 sec north of LKH-alpha198, which may be responsible for most
of the far-infrared emission in the region and for driving the molecular
flow. LKH-alpha198 appears point-like at our resolution (full width at
half maximum of approximately 1.3 sec), excluding an extended envelope
of transiently heated small grains as the dominant origin of the
mid-infrared excess in that star.
