JWST Reveals Refractory-Rich Water Ice in Interstellar Comet 3I/ATLAS: Evidence for a Continuum of Grain Properties across Protoplanetary Disks
Silvia Protopapa, Michael S. P. Kelley, Martin A. Cordiner +12
We present JWST/NIRSpec PRISM observations of the interstellar comet 3I/ATLAS obtained on 2025 August 6 (Epoch 1), 2025 December 22 (Epoch 2), and 2026 April 1 (Epoch 3), spanning…
Sky-Plane Velocity Distributions of Interstellar Objects and Implications for Their Detection
Cassidy E. Walker, Darryl Z. Seligman
In the past decade, three macroscopic-scale interstellar objects have been discovered, implying that a larger galactic population exists. In this paper, we investigate the possibil…
Assessment of the Mass Loss and Radius Change of 3I/ATLAS Based on Observed Production Rates
Tessa T. Frincke, Darryl Z. Seligman
Formed from the debris of planet formation, interstellar comets provide invaluable insights into the chemical compositions of planetary systems outside of our Solar System. Spectro…
Observational planning for the 2026 August 5 Falcon 9 Upper Stage lunar impact
Benjamin Fernando, Jennifer Heldmann, Bill Grey +20
On 2026 August 5, at approximately 06:35 UT, a spent Falcon 9 upper stage will impact the lunar surface near Einstein Crater. This event will occur on sunlit terrain near the easte…
KRONOS I: The m JWST Transmission Spectrum of the 23 Myr V1298 Tau c
Matthew M. Murphy, Matthew C. Nixon, Adina D. Feinstein +16
While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window i…
The Maximum Density of a Collisionally-Produced Planet is A Function of its Mass and Orbital Period
Madison Brady, Darryl Seligman
There are many different theoretical explanations for the formation of high-density Mercury-like planets, but concrete evidence for any of these formation mechanisms remains elusiv…
