A Survey for Satellites of Venus (2009)
Sheppard, Scott S., Trujillo, Chadwick A.
We present a systematic survey for satellites of Venus using the Baade-Magellan 6.5 meter telescope and IMACS wide-field CCD imager at Las Campanas observatory in Chile. In the outer portions of the...
An Infrared High Proper Motion Survey Using 2MASS and SDSS: Discovery of M, L and T Dwarfs (2008)
Sheppard, Scott S., Cushing, Michael C.
A search of the Two Micron All Sky Survey and Sloan Digital Sky Survey reveals 36 previously unknown high proper motion objects with J
(Abridged) I report new light curves and determine the rotations and phase functions of several large Kuiper Belt objects, including the dwarf planet Eris (2003 UB313). (120348) 2004 TY364 shows a...
Outer satellites of the planets have distant, eccentric orbits that can be highly inclined or even retrograde relative to the equatorial planes of their planets. These irregular orbits cannot have...
A Survey for "Normal" Irregular Satellites Around Neptune: Limits to Completeness (2006)
Sheppard, Scott S., Jewitt, David C., Kleyna, Jan
We surveyed 1.75 square degrees of sky near Neptune to an R-band 50% detection efficiency of 25.8 mags (corresponding to radii of about 17 km for an assumed albedo of 0.04). We discovered one new...
Ultra Deep Survey for Irregular Satellites of Uranus: Limits to Completeness (2004)
Sheppard, Scott S., Jewitt, David, Kleyna, Jan
We present a deep optical survey of Uranus' Hill sphere for small satellites. The Subaru 8-m telescope was used to survey about 3.5 square degrees with a 50% detection efficiency at limiting red...
A Survey for Outer Satellites of Mars: Limits to Completeness (2004)
Sheppard, Scott S., Jewitt, David, Kleyna, Jan
We surveyed the Hill sphere of Mars for irregular satellites. Our search covered nearly the entire Hill Sphere, but scattered light from Mars excluded the inner few arcminutes where the satellites...
Extreme Kuiper Belt Object 2001 QG298 and the Fraction of Contact Binaries (2004)
Sheppard, Scott S., Jewitt, David
Extensive time-resolved observations of Kuiper Belt object 2001 QG298 show a lightcurve with a peak-to-peak variation of 1.14 +-0.04 magnitudes and single-peaked period of 6.8872 +- 0.0002 hr. The...
Visible and infrared photometry of Kuiper Belt objects: searching for evidence of trends (2003)
McBride, Neil, Green, Simon F., Davies, John K., Tholen, David J., Sheppard, Scott S., Whiteley, Robert J., ...
We present new visible–infrared (V−J) observations of 17 Kuiper Belt objects, of which 14 were observed in the visible and infrared wavebands simultaneously to limit the effects of lightcurve...
Time-Resolved Photometry of Kuiper Belt Objects: Rotations, Shapes and Phase Functions (2002)
Sheppard, Scott S., Jewitt, David C.
We present a systematic investigation of the rotational lightcurves of trans-Neptunian objects based on extensive optical data from Mauna Kea. Four of 13 objects (corresponding to 31%) in our sample...
Physical Properties of Trans-Neptunian Object (20000) Varuna (2002)
Jewitt, David C., Sheppard, Scott S.
We present new time-resolved photometric observations of the bright trans-Neptunian object (20000) Varuna and use them to study the rotation period, shape, and color. In observations from 2001...
The Evolution of Circumstellar Disks: Lessons from the VLT and ISO (2001)
Brandner, Wolfgang, Potter, Dan, Sheppard, Scott S., Moneti, Andrea, Zinnecker, Hans
There is strong evidence that the planets in the solar system evolved from a disk-shaped solar nebula ~4.56 Gyr ago. By studying young stars in various evolutionary stages, one aims at tracing back...
