Asymmetric Structure of Uranus' Magnetopause Controlled by IMF and Planetary Rotation

Geophysical Research Letters, 2021
To investigate the diurnal variations of the magnetopause boundary under different Interplanetary Magnetic Field (IMF) orientations during the solstice season, we implemented a multifluid magnetohydrodynamic model of Uranus' magnetosphere in combination ...

Uranus and Neptune as methane planets: Producing icy giants from refractory planetesimals

Icarus (New York, N.Y. 1962)
Uranus and Neptune are commonly considered ice giants, and it is often assumed that, in addition to a solar mix of hydrogen and helium, they contain roughly twice as much water as rock.

Magnetic Fields at Uranus

Science, 1986
The magnetic field experiment on the Voyager 2 spacecraft revealed a strong planetary magnetic field of Uranus and an associated magnetosphere and fully developed bipolar magnetic tail. The detached bow shock wave in the solar wind supersonic flow was observed upstream at 23.7 Uranus radii (1 R U = 25 ...

Uranus: The Rings Are Black

Science, 1977
An upper limit of 0.05 is established for the geometric albedo of the newly discovered rings of Uranus. In view of this very low albedo, the particles of the rings cannot be ice-covered as are those of rings A and B of Saturn.

URANUS 45N

Alloy Digest, 1996
Abstract Uranus 45N (UR 45N) is a nitrogen alloyed (>0.15%) austenitic-ferritic stainless steel (2205 type) with improved structural stability and high general, localized, and stress-corrosion resistance properties. The Pitting Resistance Equivalent Number (PREN) is >33.

URANUS B46

Alloy Digest, 2007
Abstract The high chromium, molybdenum, and nitrogen contents of alloy Uranus B46 (also known as UR B46) result in a pitting resistance equivalent number (PREN) of >45 and explain why the grade is very resistant to localized corrosion even in acidified oxidizing environments. The alloy has been used for offshore applications. This
