C/2010 U3 (Boattini): A Bizarre Comet Active at Record Heliocentric Distance

We present a photometric and dynamical study of comet C/2010 U3 (Boattini), which was seen active in prediscovery data as early as 2005 November at a new inbound record heliocentric distance of rH =

A Look at Outbursts of Comet C/2014 UN271 (Bernardinelli–Bernstein) near 20 au

Cometary activity may be driven by ices with very low sublimation temperatures, such as carbon monoxide ice, which can sublimate at distances well beyond 20 au. This point is emphasized by the

The Perihelion Emission of Comet C/2010 L5 (WISE)

The only Halley-type comet discovered by the Wide-Field Infrared Survey Explorer (WISE), C/2010 L5 (WISE), was imaged three times by WISE, and it showed a significant dust tail during the second and

The Discus Comet: C/2014 B1 (Schwartz)

Long-period comet C/2014 B1 (Schwartz) exhibits a remarkable optical appearance, like that of a discus or bi-convex lens viewed edgewise. Our measurements in the four years since discovery reveal a

Dynamics of HVECs emitted from comet C/2011 L4 as observed by STEREO

High‐quality white‐light images from the Sun‐Earth Connection Coronal and Heliospheric Investigation (SECCHI) HI‐1 telescope on board STEREO‐B reveal high‐velocity evanescent clumps (HVECs) expelled


We run simulations to determine the expected distribution of orbital elements of nearly isotropic comets (NICs) in the outer solar system, assuming that these comets originate in the Oort Cloud at

Solar wind interaction with a comet: evolution, variability, and implication

Once a cometary plasma cloud has been created through ionisation of the cometary neutrals, it presents an obstacle to the solar wind and the magnetic field within it. The acceleration and

Studying Short-Period Comets and Long-Period Comets Detected by WISE/NEOWISE

The Wide-field Infrared Survey Explorer (WISE) mission surveyed the sky in four infrared wavelength bands (3.4, 4.6, 12 and 22 μm) between January 2010 and February 2011. During the mission, WISE



The Nucleus of Comet Hale-Bopp (C/1995 O1): Size and Activity

A review of our current understanding of Comet Hale-Bopp’s nuclear size is presented. Currently the best constraints on the effective radiusare derived from late-1996 mid-IR data and near-perihelion

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.

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

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

Detection of a Satellite Orbiting The Nucleus of Comet Hale–Bopp (C/1995 O1)

This paper reports on the detection of a satellite around the principal nucleus of comet Hale-Bopp. As shown elsewhere, a successful morphological model for the comet's dust coma necessitates the


Despite their small masses, comets have played an extraordinary role in enhancing our understanding of cosmic physics. It was the calculation of comet Halley's orbit and the successful prediction of

Cometary Activity at 25.7 AU: Hale-Bopp 11 Years after Perihelion

Eleven years after its perihelion, comet C/1995 O1 (Hale-Bopp) is still active. Between 2007 October 20 and 22, we detected a diffuse coma of 180 × 103 km in diameter with a slight elongation toward

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
