Considerations on the process of target selection for the Comet Interceptor mission
C. Snodgrass, E. Mazzotta Epifani, C. Tubiana +27
Comet Interceptor is an ESA science mission with payload contributions from ESA Member States and with an international participation by JAXA. It is the first mission that is being…
Evolutionary Processes in the Centaur Region
Rosita Kokotanekova, Aurélie Guilbert-Lepoutre, Matthew M. Knight +1
Centaurs populate relatively short-lived and rapidly evolving orbits in the giant-planet region and are believed to be one of the solar system's most complex and diverse population…
The Origins & Reservoirs of Exocomets
Michele Bannister, Susanne Pfalzner, Tim Pearce +11
Small bodies exist in distinct populations within their planetary systems. These reservoir populations hold a range of compositions, which to first order are dependent on formation…
Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum
Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19
The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…
First JWST spectrum of distant activity in Long Period Comet C/2024 E1 (Wierzchos)
Colin Snodgrass, Carrie E. Holt, Michael S. P. Kelley +10
We observed the new Long Period Comet C/2024 E1 (Wierzchos), inbound at 7 au from the Sun, using the NIRSpec integral field unit on JWST. The spectrum shows absorption features due…
Coma composition and profiles of comet 12P/Pons-Brooks using long-slit spectroscopy
Lea Ferellec, Cyrielle Opitom, Abbie Donaldson +4
Comet 12P/Pons-Brook exhibited multiple large and minor outbursts in 2023 on its way to its 2024 perihelion, as it has done during its previous apparitions. We obtained long-slit o…
Predictions for Sparse Photometry of Jupiter-Family Comet Nuclei in the LSST Era
A. Donaldson, C. Snodgrass, R. Kokotanekova +1
The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory will deliver high-quality, temporally-sparse observations of millions of Solar System objects on an unpreced…
Physical and Surface Properties of Comet Nuclei from Remote Observations
Matthew M. Knight, Rosita Kokotanekova, Nalin H. Samarasinha
We summarize the collective knowledge of physical and surface properties of comet nuclei, focusing on those that are obtained from remote observations. We now have measurements or…
The ESO's Extremely Large Telescope Working Groups
Paolo Padovani, Michele Cirasuolo, Remco van der Burg +82
Since 2005 ESO has been working with its community and industry to develop an extremely large optical/infrared telescope. ESO's Extremely Large Telescope, or ELT for short, is a re…
A LOOK at Outbursts of Comet C/2014 UN (Bernardinelli-Bernstein) Near 20 au
Michael S. P. Kelley, Rosita Kokotanekova, Carrie E. Holt +10
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 empha…
The LCO Outbursting Objects Key Project: Overview and Year 1 Status
Tim Lister, Michael S. P. Kelley, Carrie E. Holt +32
The LCO Outbursting Objects Key (LOOK) Project uses the telescopes of the Las Cumbres Observatory (LCO) Network to: (1) to systematically monitor a sample of Dynamically New Comets…
AMBITION -- Comet Nucleus Cryogenic Sample Return (White paper for ESA's Voyage 2050 programme)
D. Bockelée-Morvan, G. Filacchione, K. Altwegg +27
This white paper proposes that AMBITION, a Comet Nucleus Sample Return mission, be a cornerstone of ESA's Voyage 2050 programme. We summarise some of the most important questions s…
The thermal, mechanical, structural, and dielectric properties of cometary nuclei after Rosetta
O. Groussin, N. Attree, Y. Brouet +16
The physical properties of cometary nuclei observed today relate to their complex history and help to constrain their formation and evolution. In this article, we review some of th…
Properties of the Bare Nucleus of Comet 96P/Machholz 1
Nora L. Eisner, Matthew M. Knight, Colin Snodgrass +3
We observed comet 96P/Machholz 1 on a total of 9 nights before and after perihelion during its 2017/2018 apparition. Both its unusually small perihelion distance and the observed f…
Implications of the Small Spin Changes Measured for Large Jupiter-Family Comet Nuclei
Rosita Kokotanekova, Colin Snodgrass, Pedro Lacerda +3
Rotational spin-up due to outgassing of comet nuclei has been identified as a possible mechanism for considerable mass-loss and splitting. We report a search for spin changes for t…
OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary
Y. -H. Ryu, J. C. Yee, A. Udalski +106
We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two…
A dwarf planet class object in the 21:5 resonance with Neptune
Matthew J. Holman, Matthew J. Payne, Wesley Fraser +33
We report the discovery of a dwarf planet candidate by the Pan-STARRS Outer Solar System Survey. 2010 JO is red with , roughly round,…
Rotation of Cometary Nuclei: New Lightcurves and an Update of the Ensemble Properties of Jupiter-Family Comets
R. Kokotanekova, C. Snodgrass, P. Lacerda +6
We report new lightcurves and phase functions for nine Jupiter-family comets (JFCs). They were observed in the period 2004-2015 with various ground telescopes as part of the Survey…
