On the accretion of Uranus and Neptune [PDF]
, 2002 In this paper, we discuss some problems concerning the formation of Uranus and Neptune. We find that the adoption of reduced Hill spheres as the region of close interaction between planetesimals introduces an enhancement of the gravitational cross ...

New Moons of Uranus and Neptune from Ultradeep Pencil-beam Surveys
The Astronomical JournalWe have conducted extremely ultradeep pencil-beam observations for new satellites around both Uranus and Neptune. Tens of images on several different nights in 2021, 2022, and 2023 were obtained, shifted, and added together to reach as faint as 26.9 and ...

Towards an agnostic algorithm for sampling empirical structure models
Astronomy & AstrophysicsWe present an algorithm to efficiently sample the full space of planetary interior density profiles. Our approach uses as few assumptions as possible to pursue an agnostic algorithm.

Limb polarization of Uranus and Neptune
, 2006 Imaging polarimetry of Uranus and Neptune in the R, i, and z bands are presented. In all observations a radial limb polarization on the order of 1% was detected with a position angle perpendicular to the limb.

QUEST: A New Frontiers Uranus Orbiter Mission Concept Study [PDF]
, 2020 The ice giant planets, Uranus and Neptune, are fundamentally different from the gas giant and terrestrial planets. Though ice giants represent the most common size of exoplanet and possess characteristics that challenge our understanding of the way our ...
