We present high resolution, deep imaging of interstellar comet 2I/Borisov taken with the Hubble Space Telescope/Wide Field Camera 3 on 2019 October 12, November 16, December 9, 23-25 UTC (Jewitt et al. 2019a; Meech et al. 2019). Deep image stacks of 2I on all dates reveal no discernible signal from a nucleus suggesting that the coma is a strong component of 2I’s total sunlight scattering cross-section. We locate a possible jet-like structure near the optocenter of 2I 1-2′′, or 2,000 3,000 km in…

Physical Properties of Cometary Dust

Prior to the 1986 apparition of comet Halley, all attempts to determine the physical properties of cometary dust were limited to remote observations and the analysis of various particles captured by

Physical properties of cometary dust from light scattering and thermal emission

This chapter explores how physical properties of cometary dust (size distribution, composition, and grain structure) can be obtained from characteristics of the electromagnetic radiation that the
