Optical Colors as Compressed Spectral Information for Trans-Neptunian Objects

Hsing-Wen Lin, Larissa Markwardt, Kevin Napier +3

Broadband optical colors have long been recognized as tracers of the surface spectral properties of trans-Neptunian objects (TNOs), yet their relationship to near-infrared (NIR) sp…

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 long-term habitability of Earth-like planets is governed by the balance of positive and negative climate feedbacks that regulate surface temperature and atmospheric composition…

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…

Small Body Dynamics with SBDynT: Proper Elements and Chaos Analysis

Dallin Spencer, Kat Volk, Darin Ragozzine +1

The Small Body Dynamics Tool (SBDynT) is software written for the community of Solar System small body researchers to perform dynamical classification, characterization, and invest…

On the forced orbital plane of the Hilda asteroids

Ian C. Matheson, Renu Malhotra

Hilda-group asteroids librate in Jupiter's interior 3:2 mean motion resonance. We estimate that the Hilda group is observationally complete up to absolute magnitude . Th…

Analytical estimates for heliocentric escape of satellite ejecta

Jose Daniel Castro-Cisneros, Renu Malhotra, Aaron J. Rosengren

We present a general analytic framework to assess whether impact ejecta launched from the surface of a satellite can escape the gravitational influence of the planet--satellite sys…

A Terminology and Quantitative Framework for Assessing the Habitability of Solar System and Extraterrestrial Worlds

Daniel Apai, Rory Barnes, Matthew M. Murphy +13

The search for extraterrestrial life in the Solar System and beyond is a key science driver in astrobiology, planetary science, and astrophysics. A critical step is the identificat…

The vertical structure of debris discs and the role of disc gravity: A primer using a simplified model

Antranik A. Sefilian, Kaitlin M. Kratter, Mark C. Wyatt +4

Debris discs provide valuable insights into the formation and evolution of exoplanetary systems. Their structures are commonly attributed to planetary perturbations, serving as pro…

The Sensitivity to initial conditions of the Co-orbital outcomes of Lunar Ejecta

Jose Daniel Castro-Cisneros, Renu Malhotra, Aaron J. Rosengren

Lunar ejecta, produced by meteoroidal impacts, have been proposed for the origin of the near-Earth asteroid (469219) Kamo'oalewa, supported by its unusually Earth-like orbit and L-…

Asteroid Kamo`oalewa's journey from the lunar Giordano Bruno crater to Earth 1:1 resonance

Yifei Jiao, Bin Cheng, Yukun Huang +6

Among the nearly 30,000 known near-Earth asteroids (NEAs), only tens of them possess Earth co-orbital characteristics with semi-major axes 1 au. In particular, 469219 Kamo`oa…

Repelling Planet pairs by Ping-pong Scattering

Yanqin Wu, Renu Malhotra, Yoram Lithwick

The Kepler mission reveals a peculiar trough-peak feature in the orbital spacing of close-in planets near mean-motion resonances: a deficit and an excess that are a couple percent…

From Colors to Spectra and Back Again: First Near-IR Spectroscopic Survey of Neptunian Trojans

Larissa Markwardt, Hsing Wen Lin, Bryan J. Holler +4

In this work, we present 0.7-5.0 μm spectra of eight Neptunian Trojans (NTs) as observed by the JWST's NIRSpec instrument. The reddest NT, 2013 VX30, exhibits a unique spectrum wit…

Search for L5 Earth Trojans with DECam

Larissa Markwardt, David W. Gerdes, Renu Malhotra +3

Most of the major planets in the Solar System support populations of co-orbiting bodies, known as Trojans, at their L4 and L5 Lagrange points. In contrast, Earth has only one known…
