The Dust Mineralogy of Interstellar Comet 3I/ATLAS from JWST/MIRI Observations

Matthew Belyakov, Ian Wong, Carey M. Lisse +7

We present the first spectroscopic mineralogical analysis of the dust coma of an interstellar object (ISO) from JWST mid-infrared spectroscopy of 3I/ATLAS (3I). 3I exhibits a stron…

The Volatile Inventory of 3I/ATLAS as seen with JWST/MIRI

Matthew Belyakov, Ian Wong, Bryce T. Bolin +4

We present the first spectroscopic characterization of an interstellar object at mid-infrared wavelengths. Post-perihelion observations of 3I/ATLAS using the JWST/MIRI medium-resol…

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-…

Water ice in the debris disk around HD 181327

Chen Xie, Christine H. Chen, Carey M. Lisse +13

Debris disks are exoplanetary systems that contain planets, minor bodies (i.e., asteroids, Kuiper belt objects, comets, etc.), and micron-sized debris dust. Since water ice is the…

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…

Gaia and IRTF abundance of A-type main belt asteroids

Marco Delbo, Chrysa Avdellidou, Marjorie Galinier +4

The Missing Mantle Problem refers to the apparent scarcity of olivine rich (A-type) asteroids in the main belt, despite expectations that such bodies should be common if differenti…
