We present analysis of Hubble Space Telescope observations of Centaur 29P/Schwassmann–Wachmann 1 (SW1) while in outburst to characterize the outburst coma and place constraints on the nucleus’ spin state. The observations consist of Wide Field and Planetary Camera 2 (WFPC2) images from Cycle 5, GO-5829 acquired on UT 1996 March 11.3 and 12.1, which serendipitously imaged the Centaur shortly after a major outburst. A multi-component coma was detected consisting of an expanding outburst dust coma… 

CO Gas and Dust Outbursts from Centaur 29P/Schwassmann–Wachmann

29P/Schwassmann–Wachmann is an unusual solar system object. Originally classified as a short-period comet, it is now known as a Centaur that recently transferred to its current orbit, and may become

Characterization of Thermal-infrared Dust Emission and Refinements to the Nucleus Properties of Centaur 29P/Schwassmann–Wachmann 1

We present analyses of Spitzer observations of 29P/Schwassmann–Wachmann 1 using 16 μm IRS “blue” peak-up (PU) and 24 and 70 μm MIPS images obtained on UT 2003 November 23 and 24 that characterize the

The Transition from the Kuiper Belt to the Jupiter-Family (Comets)

Kuiper Belt Objects, or more generally Trans-Neptunian Objects (TNOs), are planetesimals found beyond the orbit of Neptune. Some TNOs evolve onto Neptune-crossing orbits and become Centaurs. Many

Dust Production from Mini Outbursts of Comet 29P/Schwassmann-Wachmann 1

Here we report on the results of observations of comet 29P/Schwassmann-Wachmann 1 obtained using four telescopes, in three different countries, from 2019 September 25 to 2020 January 19. During the

An Extended CO Source around Comet 29P/Schwassmann-Wachmann 1

Abstract Comet 29P/Schwassmann–Wachmann 1 has been studied during seven days in August 1998 with the SEST submillimeter telescope at ESO, La Silla, Chile. The CO ( J =2−1) emission at 230 GHz was

Outburst activity in comets – II. A multiband photometric monitoring of comet 29P/Schwassmann–Wachmann 1

We have carried out a continuous multiband photometric monitoring of the nuclear activity of comet 29P/Schwassmann–Wachmann 1 from 2008 to 2010. Our main aim has been to study the outburst mechanism

The Activity of Comet 29P/Schwassmann–Wachmann 1 Monitored through Its CO J=2→1 Radio Line☆

Abstract The 230-GHz emission from CO was observed on 18 different days between 4 December 1996 and 1 January 1997 with the 15-m SEST antenna pointed toward Comet 29P/Schwassmann–Wachmann 1. The CO

Ground-Based Infrared Detections of CO in the Centaur-comet 29P/Schwassmann-Wachmann 1 at 6.26 AU from the Sun

We observed Comet 29P/Schwassmann-Wachmann 1 (hereafter, 29P) in 2012 February and May with CRIRES/VLT and NIRSPEC/Keck-II, when the comet was at 6.26 AU from the Sun and about 5.50 AU from Earth.

Multi-aperture photometry of Comet 29P/Schwassmann-Wachmann 1 was conducted on Johnson–Cousins R-band observations spanning 2011 May 1–9 and 2012 June 6–July 3. The comet was observed in outburst on

Nucleus properties of P/Schwassmann-Wachmann 1

Time series photometric measurements are presented of Comet P/Schwassmann-Wachmann 1 at a heliocentric distance of 5.886 AU when the comet possessed an extensive coma. The light curve shows a
