On the Compositions of Interstellar Objects
Matthew J. Hopkins, Michele T. Bannister, Bertram Bitsch +2
As physical samples of distant planetary systems, the compositions of interstellar objects (ISOs) should correlate with the properties of their diverse parent stars. We combine a c…
AT 2020afjz (TSS2020a): The First Fast Extragalactic Transient Discovered by TESS
Ryan Ridden-Harper, Hugh Roxburgh, Clarinda Montilla +13
We report the discovery of AT 2020afjz (TSS2020a): the first hour-scale extragalactic transient discovered in optical wavelengths whose complete evolution -- from explosion onset t…
The ejection velocities of interstellar objects signpost their progenitor system architectures
Leah Albrow, Michele T. Bannister, John C. Forbes +1
Interstellar objects (ISOs) ejected from planetary systems carry kinematic signatures of their formation environments. The properties of these velocity distributions govern the ISO…
From a Different Star: 3I/ATLAS in the context of the Ōtautahi-Oxford interstellar object population model
Matthew J. Hopkins, Rosemary C. Dorsey, John C. Forbes +3
The discovery of the third interstellar object (ISO), 3I/ATLAS (`3I'), provides a rare chance to directly observe a small body from another Solar System. Studying its chemistry and…
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…
A portrait throughout perihelion of the NH-rich interstellar comet 2I/Borisov
Sophie E. Deam, Michele T. Bannister, Cyrielle Opitom +12
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage. We report all 16 epoc…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario Jurić +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
Semi-analytic Orbits: A Practical Implementation of Lynden-Bell's Planar Orbits and Extension to Vertical Oscillations
John C. Forbes, Michele T. Bannister, Angus Forrest +2
We present a practical implementation of the perturbation theory derived by Lynden-Bell (2015) for describing, to arbitrary precision, the orbit of a particle in an arbitrary spher…
TESSELLATE: Piecing Together the Variable Sky With TESS
Hugh Roxburgh, Ryan Ridden-Harper, Andrew Moore +13
We present TESSELLATE, a dedicated pipeline for performing an untargeted search documenting all variable phenomena captured by the TESS space telescope. Building on the TESSreduce…
The visibility of the Ōtautahi-Oxford interstellar object population model in LSST
Rosemary C. Dorsey, Matthew J. Hopkins, Michele T. Bannister +4
With a new probabilistic technique for sampling interstellar object (ISO) orbits with high efficiency, we assess the observability of ISOs under a realistic cadence for the upcomin…
Fast Radio Bursts and Interstellar Objects
Dang Pham, Matthew J. Hopkins, Chris Lintott +2
Fast radio bursts (FRBs) are transient radio events with millisecond-scale durations, and debated origins. Collisions between planetesimals and neutron stars have been proposed as…
The Volatile Composition and Activity Evolution of Main-Belt Comet 358P/PANSTARRS
Henry H. Hsieh, John W. Noonan, Michael S. P. Kelley +17
We report the detection of water vapor associated with main-belt comet 358P/PANSTARRS on UT 2024 January 8-9 using the NIRSPEC instrument aboard JWST. We derive a water production…
Starkiller: subtracting stars and other sources from IFU spectroscopic data through forward modeling
Ryan Ridden-Harper, Michele T. Bannister, Sophie E. Deam +1
We present starkiller, an open-source Python package for forward-modeling flux retrieval from integral field unit spectrograph (IFU) datacubes. Starkiller simultaneously provides s…
He awa whiria: the tidal streams of interstellar objects
John C. Forbes, Michele T. Bannister, Chris Lintott +5
Upcoming surveys are likely to discover a new sample of interstellar objects (ISOs) within the Solar System, but questions remain about the origin and distribution of this populati…
The carbon monoxide-rich interstellar comet 2I/Borisov
D. Bodewits, J. W. Noonan, P. D. Feldman +7
Interstellar comets offer direct samples of volatiles from distant protoplanetary disks. 2I/Borisov is the first notably active interstellar comet discovered in our solar system[1]…
