One EURO for Uranus: the Elliptical Uranian Relativity Orbiter mission [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Recent years have seen increasing interest in sending a mission to Uranus, visited so far only by Voyager 2 in 1986. EURO (Elliptical Uranian Relativity Orbiter) is a preliminary mission concept investigating the possibility of dynamically measuring ...

Coaccretion + Giant-impact Origin of the Uranus System: Tilting Impact [PDF]
Astrophysical Journal, 2022 The origin of the Uranian satellite system remains uncertain. The four major satellites have nearly circular, coplanar orbits, and the ratio of the satellite system to planetary mass resembles Jupiter’s satellite system, suggesting the Uranian system was

Possible In Situ Formation of Uranus and Neptune via Pebble Accretion [PDF]
Astrophysical Journal, 2022 The origin of Uranus and Neptune is still unknown. In particular, it has been challenging for planet formation models to form the planets in their current radial distances within the expected lifetime of the solar nebula.

The Promise and Limitations of Precision Gravity: Application to the Interior Structure of Uranus and Neptune [PDF]
The Planetary Science Journal, 2022 We study the constraining power of a high-precision measurement of the gravity field for Uranus and Neptune, as could be delivered by a low-periapse orbiter.

Thermal evolution of Uranus and Neptune [PDF]
Astronomy & Astrophysics, 2021 Thermal evolution models suggest that the luminosities of both Uranus and Neptune are inconsistent with the classical assumption of an adiabatic interior.

Superionic Silica-Water and Silica-Hydrogen Compounds in the Deep Interiors of Uranus and Neptune. [PDF]
Physical Review Letters, 2021 Silica, water, and hydrogen are known to be the major components of celestial bodies, and have significant influence on the formation and evolution of giant planets, such as Uranus and Neptune.

Unknown Ancient sources of Byzantine military treatises [PDF]
Hypothekai, 2021 The article is a preliminary attempt to attribute two lists of sources from Byzantine military treatises: the first one comes from the "Taktica" by the Byzantine emperor Leo VI the Wise (886-912), and the second - from "Taktika" by Nicephorus Uranus, the

Atmospheric chemistry on Uranus and Neptune. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 Comparatively little is known about atmospheric chemistry on Uranus and Neptune, because remote spectral observations of these cold, distant ‘Ice Giants’ are challenging, and each planet has only been visited by a single spacecraft during brief flybys in
