Keck Pencil-Beam Survey for Faint Kuiper Belt Objects

  title={Keck Pencil-Beam Survey for Faint Kuiper Belt Objects},
  author={Eugene Chiang and Michael E. Brown},
  journal={The Astronomical Journal},
We present the results of a pencil-beam survey of the Kuiper Belt using the Keck 10 m telescope. A single 0.01 deg^2 field is imaged 29 times for a total integration time of 4.8 hr. Combining exposures in software allows the detection of Kuiper Belt objects (KBOs) having visual magnitude m_V ≾ 27.9. Two new KBOs are discovered. One object having m_V = 25.5 lies at a probable heliocentric distance R ≈ 33 AU. The second object at m_V = 27.2 is located at R ≈ 44 AU. Both KBOs have diameters of… Expand

Large Bodies in the Kuiper Belt
We present a survey for bright Kuiper Belt objects (KBOs) and Centaurs, conducted at the Kitt Peak National Observatory (KPNO) 0.9 m telescope with the KPNO 8K Mosaic CCD. The survey imaged 164 deg2Expand
The Kuiper Belt luminosity function from mR = 22 to 25
In summer 1999, we performed a survey optimized for the discovery of irregular satellites of Uranus and Neptune. We imaged 11.85 deg 2 of sky and discovered 66 new outer Solar system objects (notExpand
A Wide-Field CCD Survey For Centaurs and Kuiper Belt Objects
A modified Baker-Nunn camera was used to conduct a wide-field survey of 1428 deg2 of sky near the ecliptic in search of bright Kuiper Belt objects and Centaurs. This area is an order of magnitudeExpand
A Deep Sky Survey of Edgeworth Kuiper Belt Objects with an Improved Shift-and-Add Method
A survey of the minor bodies in the outer regions of our solar system was carried out using the Suprime-Cam attached to the 8.2 m Subaru Telescope on Mauna Kea on 2001 February 22 and 25. SevenExpand
Population of the Scattered Kuiper Belt.
The discovery of three new scattered Kuiper Belt objects (SKBOs) from a wide-field survey of the ecliptic are presented, demonstrating that the SKBOs are similar in number and mass to the KuiPer Belt inside 50 AU. Expand
The Size Distribution of Trans-Neptunian Bodies*
We search 0.02 deg 2 of the invariable plane for trans-Neptunian objects (TNOs) 25 AU or more distant using the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope. With 22 ks perExpand
The Edge of the Solar System
We have surveyed for Kuiper Belt objects (KBOs) in six fields of the ecliptic (total sky area 1.5 deg2) to limiting magnitudes between R = 24.9 and R = 25.9. This is deep enough to detect KBOs ofExpand
Discovery of the Bright Trans-Neptunian Object 2000 EB173
We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude mR =1 8:9 and also one of theExpand
We report here initial results of the Deep Ecliptic Survey, an ongoing new search for Kuiper belt objects (KBOs) and Centaurs using the 8K × 8K Mosaic CCD array on the 4 m Mayall Telescope at KittExpand
Future Surveys of the Kuiper Belt
The next decade of Kuiper belt object (KBO) science will be completely dominated by the output of two surveys. These two surveys, the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS)Expand
