摘要：

We present continuum observations of comet P/Swift-Tuttle taken at 850 mu m wavelength using the James Clerk Maxwell Telescope. Near perihelion, it exhibited the largest submillimeter cross-section of any comet yet studied. We attribute the submillimeter emission to thermal radiation from large, near-nucleus particles destined to populate the Perseid meteor stream. The perihelion production of dust is estimated at 5x10(4) kg s(-1), and the dust to gas production ratio at similar to 2.8. (C) 1996 American Astronomical Society.
