Interstellar Comet 3I/ATLAS: Evidence for Galactic Cosmic-Ray Processing
The Astrophysical Journal LettersSpectral observations of 3I/ATLAS (C/2025 N1) with JWST/NIRSpec and SPHEREx reveal an extreme CO _2 enrichment (CO _2 /H _2 O = 7.6 ± 0.3) that is 4.5 σ above solar system comet trends and among the highest ever recorded.

The WIRC+Pol Brown Dwarf Survey: A J-band Polarimetric Survey of 22 Brown Dwarfs
The Astrophysical JournalWe present a near-infrared spectropolarimetric survey of brown dwarfs conducted with the WIRC+Pol instrument on the Palomar 200 inch Hale Telescope. The primary survey goal was to investigate the presence of polarization signatures arising from cloudy ...

A Case Study of Interstellar Material Delivery: α Centauri
The Planetary Science JournalInterstellar material has been discovered in our solar system, yet its origins and details of its transport are unknown. Here, we present α Centauri as a case study of the delivery of interstellar material to our solar system.

Spectral Characteristics of Interstellar Object 3I/ATLAS from SOAR Observations
The Astrophysical Journal LettersInterstellar objects (ISOs) provide unique insights into the building blocks and conditions of extrasolar planetary systems. The newly discovered object, 3I/ATLAS (C/2025 N1), represents the third known ISO after 1I/’Oumuamua and 2I/Borisov.

The Feasibility of a Spacecraft Flyby with the Third Interstellar Object 3I/ATLAS from Earth or Mars
The Astrophysical JournalWe investigate the feasibility of a spacecraft mission to conduct a flyby of 3I/ATLAS, the third macroscopic interstellar object discovered on 2025 July 1, as it traverses the solar system.
