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…
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…
Evolution of pits at the surface of 67P/Churyumov-Gerasimenko
Selma Benseguane, Aurélie Guilbert-Lepoutre, Jérémie Lasue +6
The observation of pits at the surface of comets offers the opportunity to take a glimpse into the properties and the mechanisms that shape a nucleus through cometary activity. If…
A molecular wind blows out of the Kuiper belt
Quentin Kral, J. E. Pringle, Aurélie Guilbert-Lepoutre +9
Gas has been detected in many exoplanetary systems (10 Myr), thought to be released in the destruction of volatile-rich planetesimals orbiting in exo-Kuiper belts. In this lette…
Interstellar comet 2I/Borisov as seen by MUSE: C, NH and red CN detections
Michele T. Bannister, Cyrielle Opitom, Alan Fitzsimmons +11
We report the clear detection of C and of abundant NH in the first prominently active interstellar comet, 2I/Borisov. We observed 2I on three nights in November 2019 at opt…
The Natural History of 'Oumuamua
Oumuamua ISSI Team
The discovery of the first interstellar object passing through the Solar System, 1I/2017 U1 ('Oumuamua), provoked intense and continuing interest from the scientific community and…
From Centaurs to comets - 40 years
Nuno Peixinho, Audrey Thirouin, Stephen C. Tegler +4
In 1977, while Apple II and Atari computers were being sold, a tiny dot was observed in an inconvenient orbit. The minor body 1977 UB, to be named (2060) Chiron, with an orbit betw…
OSSOS: XV. No active Centaurs in the Outer Solar System Origins Survey
N. Cabral, A. Guilbert-Lepoutre, W. C. Fraser +10
Context. Centaurs are icy objects in transition between the transneptunian region and the inner solar system, orbiting the Sun in the giant planet region. Some Centaurs display com…
OSSOS. VII. 800+ trans-Neptunian objects - the complete data release
Michele T. Bannister, Brett J. Gladman, J. J. Kavelaars +33
The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013-2017 with the Canada-France-Hawaii Telescope, surveyed 155 deg of sky to depths of $m_r =…
The Main Belt Comets and Ice in the Solar System
Colin Snodgrass, Jessica Agarwal, Michael Combi +11
We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout…
The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission
C. Snodgrass, M. F. A'Hearn, F. Aceituno +112
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67…
Detection of exposed HO ice on the nucleus of comet 67P/Churyumov-Gerasimenko
M. A. Barucci, G. Filacchione, S. Fornasier +42
Since the orbital insertion of the Rosetta spacecraft, comet 67P/Churyumov-Gerasimenko (67P/C-G) has been mapped by OSIRIS camera and VIRTIS spectro-imager, producing a huge quanti…
OSSOS: IV. Discovery of a dwarf planet candidate in the 9:2 resonance with Neptune
Michele T. Bannister, Mike Alexandersen, Susan D. Benecchi +32
We report the discovery and orbit of a new dwarf planet candidate, 2015 RR, by the Outer Solar System Origins Survey (OSSOS). 2015 RR's orbit is eccentric ($e=0.586…
Distant activity of 67P/Churyumov-Gerasimenko in 2014: Ground-based results during the Rosetta pre-landing phase
Colin Snodgrass, Emmanuel Jehin, Jean Manfroid +14
As the ESA Rosetta mission approached, orbited, and sent a lander to comet 67P/Churyumov-Gerasimenko in 2014, a large campaign of ground-based observations also followed the comet.…
The Outer Solar System Origins Survey: I. Design and First-Quarter Discoveries
Michele T. Bannister, J. J. Kavelaars, Jean-Marc Petit +36
We report the discovery, tracking and detection circumstances for 85 trans-Neptunian objects (TNOs) from the first 42 deg of the Outer Solar System Origins Survey (OSSOS). Th…
The albedo-color diversity of transneptunian objects
Pedro Lacerda, Sonia Fornasier, Emmanuel Lellouch +9
We analyze albedo data obtained using the Herschel Space Observatory that reveal the existence of two distinct types of surface among midsized transneptunian objects. A color-albed…
The Bimodal Colors of Centaurs and Small Kuiper Belt Objects
Nuno Peixinho, Audrey Delsanti, Aurélie Guilbert-Lepoutre +2
Ever since the very first photometric studies of Centaurs and Kuiper Belt Objects (KBOs) their visible color distribution has been controversial. That controversy gave rise to a pr…
Methane, ammonia, and their irradiation products at the surface of an intermediate-size KBO? A portrait of Plutino (90482) Orcus
Audrey Delsanti, Frédéric Merlin, Aurélie Guilbert +3
Orcus is an intermediate-size 1000km-scale Kuiper Belt Object in 3:2 mean-motion resonance with Neptune, in an orbit very similar to that of Pluto. We present visible and near-infr…
