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
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
Analysis of HST WFPC2 Observations of Centaur 29P/Schwassmann–Wachmann 1 while in Outburst to Place Constraints on the Nucleus’ Rotation State
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
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
Thermodynamic model of comet 29P/SW brightness changing
We analyze the thermodynamic model of changes in comet brightness focusing on the exceptional case which is comet 29P/Schwassmann-Wachmann (hereafter 29P/SW). This object demonstrates quasi-regular


Spitzer Observations of the Dust Coma and Nucleus of 29P/Schwassmann-Wachmann 1
We obtained thermal images and spectra of comet and Centaur object 29P/Schwassmann-Wachmann 1 in late 2003 November. Images at 8, 24, and 70 μm reveal an extensive coma. At 24 μm the coma extends at
Spitzer Space Telescope Observations of the Nucleus of Comet 103P/Hartley 2
We have used the Spitzer Space Telescope InfraRed Spectrograph (IRS) 22-μm peakup array to observe thermal emission from the nucleus and trail of comet 103P/Hartley 2, the target of NASA’s Deep
We have used the Spitzer Space Telescope Infrared Spectrograph (IRS) to observe the 5–37 μm thermal emission of comet 73P/Schwassmann-Wachmann 3 (SW3), components B and C. We obtained low spectral
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
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
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
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
Activity of Comet 29P/Schwassmann–Wachmann 1
The outbursts of the comet 29P/Schwassmann‐Wachmann 1: A new approach to the old problem
As far as outbursts activity is concerned, the 29P/Schwassmann-Wachmann 1 is the exceptional comet. This Centaur object shows quasi-regular flares with periodicities of 50 days (Trigo-Rodriguez et
