Detection of Extended Thermal Infrared Emission around the Vega-like Source HD 141569
{{output}}
We report the detection of extended IR emission at 10.8 and 18.2 µm around the Vega-like source HD 141569. Mid-IR imaging with OSCIR on Keck II shows emission from dust extending out to 100 AU from the B9.5 Ve star. Our modeling of the dust places an upper li... ...
