The forced orbital planes of the Plutinos and other resonant KBOs
Ian Matheson, Renu Malhotra
The forced plane of non-resonant minor planets has been understood to be well-estimated by the local Laplace plane given by linear Laplace-Lagrange secular perturbation theory, but…
When Stabilizing Feedbacks Wreak Havoc in Habitable Planets: Chaos at the Freezing Point in a Four-Feedback Climate Model
Chaucer Langbert, Dániel Apai, Renu Malhotra
The authors extend a simple climate model of Earth‑like planets with an extra feedback and run tens of thousands of simulations, showing that chaotic climate behavior can arise esp…
Extreme Debris Disks: Insights into Violent Collisions in Planet Formation and Destruction
Kate Y. L. Su, Attila Moor, Agnes Kospal +7
Debris disks are dusty structures around mature stars, primarily identified by infrared excesses in the stellar spectra. A subset, known as extreme debris disks (EDDs), exhibits st…
A long-term spectro-temporal study of Jovian X-ray and Ultraviolet response to solar activity
Megha Tomer, Mayukh Pahari, Anurag Baruah +1
We present results from a multi-decade investigation of solar activity-driven variability in Jupiter's emissions, using solar X-ray flux and sunspot numbers as activity indicators…
Probabilistic Spectral Reconstruction of Trans-Neptunian Objects from Sparse Photometry: A Framework for Taxonomy, Survey Optimization, and Outlier Detection
Hsing Wen Lin, Larissa Markwardt, Kevin J. Napier +3
Near-infrared (near-IR) spectroscopy provides critical constraints on the surface composition of trans-Neptunian objects (TNOs), but spectroscopic observations remain limited compa…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario JuriÄ +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-…
