Red, Gray, and Blue: Near Infrared Spectrophotometryof Faint Moons of Uranus and Neptune
Using the CoCo Cold Coronagraph at NASA’s Infrared Telescope Facility on Mauna Kea, we observed the uranian satellites Miranda, Puck, Portia, and Rosalind and the neptunian satellite Proteus in the near infrared (JHK) to determine the albedos of those faint satellites. In V-J, all of Puck, Portia, Rosalind, and Proteus are very blue, similar to the colors of many icy satellites and of water ice...

متن کاملThe Rings of Uranus: Shepherded, or Not?
I investigate the hypothesis that small, unseen moons are “shepherding” the main rings of Uranus. The ring edges are expected to be confined at the discrete locations of Lindblad resonances, where the moon’s influence produces a wavy edge. For a narrow, optically thick ring, this interaction manifests itself as a periodic variation in the ring’s brightness. Under many circumstances, the induced...
متن کاملDynamics of Distant Moons of Asteroids
solar perturbations dominate. Since the detailed mass distribution within the asteroid is relatively unimportant in We introduce a new analytic method for treating the orbital motions of objects about asteroids and planets. For an asteroid this regime, orbits about one asteroid are similar to those following a circular path around the Sun, we rewrite Jacobi’s about another as long as the eccent...
متن کاملUranus’ aurorae past equinox
The aurorae of Uranus were recently detected in the far 2 ultraviolet with the Hubble Space Telescope (HST) pro3 viding a new, so far unique, means to remotely study the 4 asymmetric Uranian magnetosphere from Earth. We ana5 lyze here two new HST Uranus campaigns executed in Sept. 6 2012 and Nov. 2014 with different temporal coverage and 7 under variable solar wind conditions numerically predic...
