The detection of Interstellar Objects passing through the Solar System offers the promise of constraining the physical and chemical processes involved in planetary formation in other extrasolar systems. While the effect of outgassing by 1I/2017 U1 ('Oumuamua) was dynamically observed, no direct detection of the ejected material was made. The discovery of the active interstellar comet 2I/Borisov means spectroscopic investigations of the sublimated ices is possible for this object. We report the…

Detection of a Water Tracer in Interstellar Comet 2I/Borisov
We present high spectral resolution optical spectra obtained with the ARCES instrument at Apache Point Observatory showing detection of the [OI]6300 A line in interstellar comet 2I/Borisov. We employ
Searching for water ice in the coma of interstellar object 2I/Borisov
Interstellar Objects (ISO) passing through our Solar System offer a rare opportunity to probe the physical and chemical processes involved in solid body and planet formation in extrasolar systems.
Spectrosopy of interstellar comet 2I/Borisov with VLT X-Shooter
<p><strong>Abstract</strong></p> <p>During the journey through the solar system, interstellar comet 2I/Borisov has been observed spectroscopically by most of the largest telescopes on Earth, enabling
Gaseous atomic nickel in the coma of interstellar comet 2I/Borisov.
Spectroscopic observations of atomic nickel vapour in the cold coma of 2I/Borisov at a heliocentric distance of 2.322 astronomical units are reported, in line with the recent identification of this atom-as well as iron-in the cold comae of Solar System comets17.
The similarity of the interstellar comet 2I/Borisov to Solar System comets from high-resolution optical spectroscopy
Aims. 2I/Borisov hereafter 2I is the first visibly active interstellar comet observed in the solar system, allowing us for the first time to sample the composition of a building block from another
Interstellar comet 2I/Borisov as seen by MUSE: C 2 , NH 2 and red CN detections
We report the clear detection of C 2 and of abundant NH 2 in the first prominently active interstellar comet, 2I/Borisov. We observed 2I on three nights in November 2019 at optical wavelengths
A search for the origin of the interstellar comet 2I/Borisov
The discovery of the second interstellar object 2I/Borisov on 2019 August 30 raises the question of whether it was ejected recently from a nearby stellar system. Here we compute the asymptotic
2I/Borisov: A C2-depleted interstellar comet
Aims. The discovery of the first active interstellar object 2I/Borisov provides an unprecedented opportunity to study planetary formation processes in another planetary system. In particular,
Activity of the first interstellar comet 2I/Borisov around perihelion: results from Indian observatories
Comet 2I/Borisov is the first true interstellar comet discovered. Here we present results from observational programs at two Indian observatories, 2 m Himalayan Chandra Telescope at the Indian
Water Production Rates and Activity of Interstellar Comet 2I/Borisov
We observed the interstellar comet 2I/Borisov using the Neil Gehrels-Swift Observatory's Ultraviolet/Optical Telescope. We obtained images of the OH gas and dust surrounding the nucleus at six epochs


Initial characterization of interstellar comet 2I/Borisov
Interstellar comets penetrating through the Solar System had been anticipated for decades 1 , 2 . The discovery of asteroidal-looking ‘Oumuamua 3 , 4 was thus a huge surprise and a puzzle.
Spitzer Observations of Interstellar Object 1I/‘Oumuamua
1I/'Oumuamua is the first confirmed interstellar body in our solar system. Here we report on observations of 'Oumuamua made with the Spitzer Space Telescope on 2017 November 21–22 (UT). We integrated
Ground-based monitoring of comet 67P/Churyumov-Gerasimenko gas activity throughout the Rosetta mission
Simultaneously to the ESA Rosetta mission, a world-wide ground-based campaign provided measurements of the large scale activity of comet 67P/Churyumov-Gerasimenko through measurement of optically
Dust measurements in the coma of comet 67P/Churyumov-Gerasimenko inbound to the Sun
The largest orbiting clumps are meter-sized, confirming the dust/gas ratio of 3 inferred at perihelion from models of dust comae and trails.
An Observational Upper Limit on the Interstellar Number Density of Asteroids and Comets
We derived 90% confidence limits (CL) on the interstellar number density ($\rho_{IS}^{CL}$) of interstellar objects (ISO; comets and asteroids) as a function of the slope of their size-frequency
A brief visit from a red and extremely elongated interstellar asteroid
Observations and analysis of the object 1I/2017 U1 (‘Oumuamua) that demonstrate its extrasolar trajectory, and that enable comparisons to be made between material from another planetary system and from the authors' own, reveal it to be asteroidal with no hint of cometary activity despite an approach within 0.25 astronomical units of the Sun.
Narrowband-filter photometry of Comet 96P/Machholz 1 was obtained at Lowell Observatory during the comet's 2007 apparition. Production rates of OH, CN, C2, C3, and NH were derived from these data
Tumbling motion of 1I/‘Oumuamua and its implications for the body’s distant past
Models of the Solar System’s evolution show that almost all the primitive material leftover from the formation of the planets was ejected to the interstellar space as a result of dynamical
Early photometry of comet p/Halley: Development of the Coma
Abstract Broadband charge-coupled device photometry of Comet p/Halley at heliocentric distances R = 5.9 AU (1984 October) and R = 5.1 AU (1985 January) is presented. The mean brightness at R = 5.1 AU
Observational Constraints on the Lifetime of Cometary H2O
Abstract We used a carefully selected set of observations of five comets along with a vectorial model and the Haser model to explore the lifetimes against photodissociation of H 2 O and OH in
