Effects of a giant impact on Uranus [PDF]
The effects of a giant impact on Uranus with respect to the axis tilt of Uranus and its satellites are discussed. The simulations of possible giant impacts were carried out using Cray supercomputers.

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.

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 ...

Astronomical studies of the major planets, natural satellites and asteroids using the 2.24 m telescope [PDF]
Directional features in the Jovian sodium torus, high quality CCD images of the major planets, methane bands in the spectrum of Triton, the central wavelength of the SO2 absorption band on Io, a component on the icy surfaces of the satellites of Uranus ...

Nature Communications, 2017 The cosmic optical background is an important cosmological observable. Here the authors show that a direct observation of the background brightness from the outer solar system can be obtained by the LORRI instrument aboard the New Horizons mission, on ...

Orbital dynamics of the Uranian satellites based on Voyager data [PDF]
The satellites of Uranus all have significant non-zero eccentricities and in the case of Miranda a significant inclination as well. The Voyager 2 encounter with Uranus in January 1986, provided more accurate estimates of the masses and sizes of the ...

Possible radio emission from Uranus at 0.5 MHz [PDF]
Radio emission from the direction of Uranus was detected in data from the radio astronomy experiment on the IMP-6 spacecraft. Previously, emission from the direction of Jupiter and Saturn was observed by the IMP-6 at a number of frequencies near 1 MHz ...

Are the aerosols on Uranus and Neptune composed of methane photopolymers? [PDF]
The measured optical properties of photochemically produced aerosols in an adding-doubling radiative transfer code were used to match various points in the spectra of Uranus and Neptune.

Radio Science Experiments during a Cruise Phase to Uranus
AerospaceThe exploration of Uranus, a key archetype for ice giant planets and a gateway to understanding distant exoplanets, is acquiring increasing interest in recent years, especially after the Uranus Orbiter and Probe (UOP) mission has been prioritized in the ...
