The Perturbation Theory Approach to Stability in the Scattered Disk
Matthew Belyakov, Konstantin Batygin
Scattered disk objects (SDOs) are distant minor bodies that orbit the sun on highly eccentric orbits, frequently with perhelia near Neptune's orbit. Gravitational perturbations due…
Very Large Telescope Observations of Interstellar Comet 3I/ATLAS. II. From Quiescence to Glow: Dramatic Rise of Ni i Emission and Incipient CN Outgassing at Large Heliocentric Distances*
Rohan Rahatgaonkar, Juan Pablo Carvajal, Thomas H. Puzia +25
We report VLT spectroscopy of the interstellar comet 3I/ATLAS (C/2025~N1) from to ~au using X-shooter (300--550\,nm, ) and UVES (opt…
Interstellar comet 3I/ATLAS: discovery and physical description
Bryce T. Bolin, Matthew Belyakov, Christoffer Fremling +18
We describe the physical characteristics of interstellar comet 3I/ATLAS, discovered on 2025 July 1 by the Asteroid Terrestrial-impact Last Alert System. The comet has eccentricity,…
Palomar and Apache Point Spectrophotometry of Interstellar Comet 3I/ATLAS
Matthew Belyakov, Christoffer Fremling, Matthew J. Graham +7
On July 1st 2025 the third interstellar object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered, with an eccentricity of and perihelion of au. We…
Multi-epoch spectro-photometric characterization of the minimoon 2024 PT in the visible and near-infrared
Jin Beniyama, Bryce T. Bolin, Alexey V. Sergeyev +5
2024 PT is a tiny ( m) near-Earth asteroid (NEA) discovered in August 2024. 2024 PT was gravitationally bound to the Earth-Moon system from September to November 2…
JWST Near Infrared Spectroscopy of High Albedo Jupiter Trojans: A New Surface Type in the Trojan Belt
Michael E. Brown, Ian Wong, Matthew Belyakov
We present 0.8 to 5 m JWST spectra of four 20 km diameter Jupiter Trojans known to have albedos elevated above the values typical in the remaining Trojan population. The s…
A JWST study of CO on the satellites of Saturn
Michael E. Brown, Samantha K. Trumbo, Matthew Belyakov +2
Solid state CO has been detected throughout the outer solar system, even at temperatures where crystalline CO is unstable, requiring that the CO be trapped in a separat…
Saturnian Irregular Satellites as a Probe of Kuiper Belt Surface Evolution
Matthew Belyakov, Michael E. Brown
We present the JWST NIRSpec PRISM 0.7-5.3 micron spectra of Albiorix and Siarnaq and the NIRSpec G235H/G395M 1.7-5.3 micron spectra of Phoebe, the three largest Saturnian irregular…
Keck and Gemini characterization of rendezvous target 1998 KY
Bryce T. Bolin, Christoffer Fremling, Matthew Belyakov +7
Near-earth object (NEO) 1998 KY is a target of the spacecraft, which it will rendezvous with in July 2031. The asteroid is a rapid rotator and has a large out-…
