Large particles may be present in comets in numbers sufficient to dominate the total mass of the coma. These large particles are not readily sensed by conventional (optical - infrared) techniques but are prominent at submillimeter wavelengths. Images taken using a new camera sensitive to submillimeter wavelengths reveal that comet Hale-Bopp was a prodigious source of particulate matter, releasing dust at 2000 metric tons per second when near perihelion and contributing 3 × 1013 kg to the…

Infrared Observations Of Dust Emission From Comet Hale-Bopp

We present infrared imaging and photometry of the bright, giant comet C/1995 O1 (Hale-Bopp). The comet was observed in an extended infrared and optical observing campaign in 1996–1997. The infrared

Morphological Structure and Chemical Composition of Cometary Nuclei and Dust

The chemical composition of comet nuclei derived from current data on interstellar dust ingredients and comet dust and coma molecules are shown to be substantially consistent with each other in both

A search for trends in cometary dust emission

Observations of Unusually Small Dust Grains in the Coma of Comet Hale-Bopp C/1995 O1

We present 1.2-18.3 μm photometry of comet 1995 01 (Hale-Bopp). Our observations spanned nearly 4 months pre- and post-perihelion. The dust grain size-dependent parameters of superheat, 10 μm

A Search for Trends in Cometary Dust Emission

We present the results of searching for statistical trends in the properties of dust emitted by 9 comets as determined using mid-IR observations. Trends in the aggregate dataset of dust PSD, total

On the Role of Dust Mass Loss in the Evolution of Comets and Dusty Disk Systems

We present the results of an ongoing optical/thermal infraredphotometric imaging survey of thedust mass loss and nuclear size ofcomets. We find an evolution with time of the kind of dust emittedfrom

CATASTROPHIC DISRUPTION OF COMET ISON

We report submillimeter 450 and 850 μm dust continuum observations for comet C/2012 S1 (ISON) obtained at heliocentric distances 0.31–0.08 au prior to perihelion on 2013 November 28 (rh = 0.0125 au).

Radio observations of Jupiter-family comets

Compact pebbles and the evolution of volatiles in the interstellar comet 2I/Borisov

The interstellar traveler, 2I/Borisov, is the first clearly active extrasolar comet, ever detected in our Solar system. We obtained high-resolution interferometric observations of 2I/Borisov with the

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

The submillimeter radio continuum of Comet P/Brorsen-Metcalf

Observations of Comet P/Brorsen-Metcalf in the submillimeter radio continuum are presented. The observations were taken using the James Clerk Maxwell Telescope on Mauna Kea, and include the first

From Interstellar Dust to Comets: Infrared Emission from Comet Hale-Bopp (C/1995 O1)

The 3-20 μm IR thermal emission spectrum of comet Hale-Bopp (C/1995 O1) at a heliocentric distance of rh=1.15 AU has been calculated using fluffy aggregates of silicate core-organic refractory mantle

Submillimeter Continuum Emission from Comets

Measurement of Submicron Grains in the Coma of Comet Hale-Bopp C/1995 O1 during 1997 February 15-20 UT

We present 1.20-18.5 μm infrared (IR) spectrophotometric measurements of comet C/1995 O1 (Hale-Bopp) during 1997 February 15 and 20 UT. The spectral energy distribution (SED) was dominated by

Dust particle impacts during the Giotto encounter with comet Grigg–Skjellerup

IN the European Space Agency's 1992 Giotto Extended Mission, the Dust Impact Detection System operated successfully during a fly-by that took the spacecraft within about 200 km of the nucleus of

THE PREPERIHELION DUST ENVIRONMENT OF C/1995 O1 HALE-BOPP FROM 13 TO 4 AU

Two UK Schmidt plates of comet Hale-Bopp dust tail taken in 1996 May are analyzed by means of the inverse dust tail model. The dust tail fits are the only available tools providing estimates of the

Radar detection of the nucleus and coma of comet hyakutake

TLDR
Radar observations of comet Hyakutake (C/1996 B2) made at the Goldstone Deep Space Communications Complex in California have detected echoes from the nucleus and from large grains in the inner coma, providing evidence that large grains constitute an important component of the mass loss from a typical active comet.

Photometric Behavior of Comet Hale-Bopp (C/1995 O1) Before Perihelion

Narrowband photometric observations of comet Hale-Bopp (C/1995 O1) between 25 July 1995 and 15 February 1997 indicated gas and dust production rates of 20 and 100 times greater, respectively, than

Spectrophotometry of 25 comets - Post-Halley updates for 17 comets plus new observations for eight additional comets
