Activity of most comets near the Sun is dominated by sublimation of frozen water, the most abundant ice in comets. Some comets, however, are active well beyond the water-ice sublimation limit of ~3 AU. Three bodies dominate the observational record and modeling efforts for distantly active comets: the long-period comet C/1995 O1 Hale-Bopp and the short-period comets (with Centaur orbits) 29P/Schwassmann Wachmann 1 and 2060 Chiron. We summarize what is known about these three objects emphasizing…

Carbon Monoxide in the Distantly Active Centaur (60558) 174P/Echeclus at 6 au
(60558) 174P/Echeclus is an unusual object that belongs to a class of minor planets called Centaurs, which may be intermediate between Kuiper Belt Objects and Jupiter Family comets. It is
A Comet Active Beyond the Crystallization Zone
We present observations showing in-bound long-period comet C/2017 K2 (PANSTARRS) to be active at record heliocentric distance. Nucleus temperatures are too low (60 K to 70 K) either for water ice to
Cometary Activity Discovered on a Distant Centaur: A Nonaqueous Sublimation Mechanism
Centaurs are minor planets thought to have originated in the outer Solar System region known as the Kuiper Belt. Active Centaurs enigmatically display comet-like features (e.g., tails, comae) even
Physical activity of the selected nearly isotropic comets with perihelia at large heliocentric distance
Context. The systematic investigation of comets in a wide range of heliocentric distances can contribute to a better understanding of the physical mechanisms that trigger activity at large distances
Observations of distant comet C/2011 KP36 (Spacewatch): photometry, spectroscopy, and polarimetry
Aims. The main objective of our study is to obtain new observational results for the active long-period comet C/2011 KP36 (Spacewatch). This comet has unusual orbital properties and moves at
Analysis of Nucleus Properties of the Enigmatic Comet 29P/Schwassmann-Wachmann 1
We present results from a continuing effort to understand activity drivers for the enigmatic Comet 29P/Schwassmann-Wachmann 1 (SW1). SW1 has been of interest since its discovery almost 100 years ago
Hubble Space Telescope Search for Activity in High-perihelion Objects
Solar system objects with perihelia beyond the orbit of Jupiter ($q >$ 5 AU) are too cold for water ice to generate an appreciable coma via sublimation. Despite this, numerous high perihelion objects
The Visual Lightcurve of Comet C/1995 O1 (Hale–Bopp) from 1995 to 1999
The great comet C/1995 O1 (Hale–Bopp) presented a remarkable opportunity to study its long-term brightness over four years. We used 2240 observations published in the International Comet Quarterly
Characterization of material around the centaur (2060) Chiron from a visible and near-infrared stellar occultation in 2011
The centaur (2060) Chiron exhibits outgassing behaviour and possibly hosts a ring system. On 2011 November 29, Chiron occulted a fairly bright star (R ∼ 15 mag) as observed from the 3-m NASA


Substantial outgassing of CO from comet Hale–Bopp at large heliocentric distance
The detection of CO emission from Hale–Bopp is reported, at levels indicating a very large rate of outgassing, and it is anticipated that future observations will reveal the onset of sublimation of other volatile species as the comet continues its present journey towards the Sun.
We describe recent results on the CO/CO2/H2O composition of comets together with a survey of older literature (primarily for CO/H2O) and compare these with models of the protoplanetary disk. Even
Identification of two sources of carbon monoxide in comet Hale–Bopp
Observations of comet Hale-Bopp show that about half of the CO in the comet comes directly from ice stored in the nucleus, suggesting that the ices underwent some processing before their inclusion into Hale–Bopp.
An Analysis of CO Production in Cometary Comae
Understanding the sources of CO in cometary comae is important for understanding comet chemistry and the roles comets have played in the development of the solar system. Among comets sampled to date,
The distant activity of short-period comets – I
A surprisingly large number of short-period comets have been observed with significant activity (a coma and even a well-developed dust tail) at heliocentric distances greater than 3 au, where the
Long-term Evolution of the Outgassing of Comet Hale-Bopp From Radio Observations
C/1995 O1 (Hale-Bopp) has been observed on a regular basis since August 1995 at millimetre and submillimetre wavelengths using IRAM, JCMT, CSO and SEST radio telescopes. The production rates of eight
The Cometary Activity of Chiron: A Stratigraphic Model☆
Abstract A theoretical model of a comet nucleus composed of H2O ice, a highly volatile ice, and nonvolatile material is used to simulate the recently observed comet-like activity of minor planet
Coma formation driven by carbon monoxide release from comet Schwassmann–Wachmann 1
DISTANT comets are sometimes observed to undergo outbursts of activity that generate a surrounding coma, but the cause of this activity is not known1,2. Whereas such outbursts in near-Sun comets are
A Model for the Distant Activity of Comet Hale-Bopp
Numerical simulations of the evolving activity of comet Hale-Bopp are presented. A porous, spherical nucleus, 20 km in radius, made of ice and dust in equal mass fractions, is considered, assuming 5%
Evolution of the Outgassing of Comet Hale-Bopp (C/1995 O1) from Radio Observations
Spectra obtained from ground-based radio telescopes show the progressive release of CO, CH3OH, HCN, H2O (from OH), H2S, CS, H2CO, CH3CN, and HNC as comet Hale-Bopp (C/1995 O1) approached the sun from
