The Size Distribution of Trans-neptunian Bodies
We search 0.02 deg 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 per pointing, the search is more than 50% complete for m606W 29:2. Three new objects are discovered, the faintest with mean magnitude m 1⁄4 28:3 (diameter 25 km), which is 3 mag fainter than any previously w...
متن کاملDiscovery of the Bright Trans - Neptunian Object 2000 EB 173
We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude mR = 18.9 and also one of the largest Plutinos, found with the drift-scanning camera of the QUEST Collaboration, attached to the 1-m Schmidt telescope of the National Observatory of Venezuela. We measure B − V = 0.99± 0.14 and V −R =...
متن کاملPhysical Properties of Trans - Neptunian Object ( 20000 ) Varuna
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 February and April, we find a best-fit two-peaked lightcurve with period 6.3442 ± 0.0002 hr. The peak-to-peak photometric range in the R-band is 0.42± 0.02 mag. We find no rotational variation in colors o...
متن کاملPluto: A Planet or a Trans-Neptunian Object?
The purposes of classification and taxonomy are reviewed. Using examples from fields ranging from paleontology to planetology, I argue that non-exclusive classifications, which allow Pluto to be considered both a planet and a TNO, provide the most desirable approach to progress in our science.
متن کاملThe Extraordinary Colors of Trans-Neptunian Objects
In 1992, Jewitt and Luu (1993) carried out a survey of 0.7 square degrees of the sky to a limiting magnitude of We present B–V and V–R colors for trans-neptunian objects (TNOs) 1994 TB and 1993 SC. We have found that these TNOs R p 25 and discovered the first TNO (1992 QB1). Thirtyhave colors almost as red as 5145 Pholus which are therefore six TNOs have been discovered as of June, 1996. The co...
