AN ULTRADEEP SURVEY FOR IRREGULAR SATELLITES OF URANUS: LIMITS TO COMPLETENESS
@article{Sheppard2005ANUS, title={AN ULTRADEEP SURVEY FOR IRREGULAR SATELLITES OF URANUS: LIMITS TO COMPLETENESS}, author={Scott S. Sheppard and David C. Jewitt and Jan T. Kleyna}, journal={The Astronomical Journal}, year={2005}, volume={129}, pages={518-525} }
We present a deep optical survey of Uranus's Hill sphere for small satellites. The 8 m Subaru Telescope was used to survey about 3.5 square degrees with a 50% detection efficiency at limiting red magnitude mR = 26.1. This magnitude corresponds to objects that are about 7 km in radius (assuming an albedo of 0.04). We detected (without prior knowledge of their positions) all previously known outer satellites and discovered two new irregular satellites (S/2001 U2 and S/2003 U3). The two inner…
