The anomalous state of Uranus's magnetosphere during the Voyager 2 flyby. [PDF]
Nat AstronThe Voyager 2 flyby of Uranus in 1986 revealed an unusually oblique and off-centred magnetic field. This single in situ measurement has been the basis of our interpretation of Uranus’s magnetosphere as the canonical extreme magnetosphere of the solar ...

Detection of the infrared aurora at Uranus with Keck-NIRSPEC [PDF]
Nature Astronomy, 2023 Near-infrared (NIR)-wavelength observations of Uranus have been unable to locate any infrared aurorae, despite many attempts to do so since the 1990s.

Empirical structure models of Uranus and Neptune [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Uranus and Neptune are still poorly understood. Their gravitational fields, rotation periods, atmosphere dynamics, and internal structures are not well determined.

Compositions and Interior Structures of the Large Moons of Uranus and Implications for Future Spacecraft Observations. [PDF]
J Geophys Res Planets, 2023 The five large moons of Uranus are important targets for future spacecraft missions. To motivate and inform the exploration of these moons, we model their internal evolution, present‐day physical structures, and geochemical and geophysical signatures ...

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

Temporal and Seasonal Evolution of Uranus' Exosphere
, 2021 International audienceUranus' thermospheric temperature has been observed to decrease with time since 1990. The effect of this steady cooling on its exospheric density distribution and escape is yet to be determined.

Tilting Uranus via the migration of an ancient satellite [PDF]
Astronomy & Astrophysics, 2022 Context. The 98{\deg}-obliquity of Uranus is commonly attributed to giant impacts that occurred at the end of the planetary formation. This picture, however, is not devoid of weaknesses. Aims.

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.

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
