NEOMOD 2: An updated model of Near-Earth Objects from a decade of Catalina Sky Survey observations
Granvik, Mikael; Chodas, Paul W.; Nesvorný, David +9 more
Catalina Sky Survey (CSS) is a major survey of Near-Earth Objects (NEOs). In a recent work, we used CSS observations from 2005-2012 to develop a new population model of NEOs (NEOMOD). CSS's G96 telescope was upgraded in 2016 and detected over 10,000 unique NEOs since then. Here we characterize the NEO detection efficiency of G96 and use G96's NEO …
The Uranus system from occultation observations (1977-2006): Rings, pole direction, gravity field, and masses of Cressida, Cordelia, and Ophelia

From an analysis of 31 Earth-based stellar occultations and three Voyager 2 occultations spanning 1977-2006 (French et al. 2023a), we determine the keplerian orbital elements of the centerlines of the nine main Uranian rings to high accuracy, with typical RMS residuals of 0.2-0.4 km and 1- σ formal errors in a , ae , and a sin i of order 0.1 km, r…
