Rotation rates of Kuiper-belt objects from their light curves

  author={W. Romanishin and Stephen C. Tegler},
Very little is known about the physical properties of Kuiper-belt objects, due to their relatively small size and large distance from the Earth. For example, a Kuiper-belt object with a diameter of 300 km at a typical distance of ∼30 AUwould subtend an angle of only 0.014 arcsec. It is therefore possible to investigate their surface markings, shapes and rotational properties only through variations in the light that they reflect (their light curves). Here we report a survey of optical light… 

The shapes and spins of Kuiper belt objects

We present a statistical study of the detectability of lightcurves of Kuiper Belt objects (KBOs). Some Kuiper Belt objects display lightcurves that appear ”flat”, i.e., there are no significant

Time-resolved Photometry of Kuiper Belt Objects: Rotations, Shapes, and Phase Functions

We present a systematic investigation of the rotational light curves of trans-Neptunian objects based on extensive optical data from Mauna Kea. Four of 13 objects (corresponding to 31%) in our sample

Analysis of the Rotational Properties of Kuiper Belt Objects

We use optical data on 10 Kuiper Belt objects (KBOs) to investigate their rotational properties. Of the 10, 3 (30%) exhibit light variations with amplitude Δm ≥ 0.15 mag, and 1 out of 10 (10%) has Δm

Light Curves of 20-100 km Kuiper Belt Objects Using the Hubble Space Telescope

We report high-precision photometry of three small and one larger Kuiper Belt objects (KBOs) obtained with the Advanced Camera for Surveys on board the Hubble Space Telescope. The three small bodies

1998 SM165: A large Kuiper belt object with an irregular shape

Observations of the Kuiper belt object 1998 SM165 indicate its brightness periodically varies by 0.56 magnitudes over a 4-h interval, which would put it among the largest elongated objects known in the authors' solar system.

Light Curves and Rotational Properties of the Pristine Cold Classical Kuiper Belt Objects

We present a survey of the rotational and physical properties of the dynamically low inclination Cold Classical (CC) trans-Neptunian objects (TNOs). The CCs are primordial planetesimals and contain


We reexamine the correlation between the colors and the inclinations of the Classical Kuiper Belt Objects (CKBOs) with an enlarged sample of optical measurements. The correlation is strong (ρ = −0.7)

Hawaii Kuiper Belt Variability Project: An Update

We have been systematically monitoring a large sample of bright Kuiper Beltobjects for possible light variations due to rotational and phase angle effects.Here we report on three objects, 2003 AZ84,



Two distinct populations of Kuiper-belt objects

The discovery of the first member of the Kuiper belt—a formerly hypothetical ancient reservoir of objects located beyond Neptune's orbit—started a revolution in our understanding of the outer Solar

CCD Photometry of the Centaur 1995 GO

Abstract We present new CCD photometry of the Centaur object 1995 GO obtained in April 1996, including a lightcurve, a V − R color, and a surface brightness profile. The apparent brightness implies a

Photometry of the Trans-Neptunian Object 1993 SC

We obtained broadband photometry of the Trans-Neptunian Object 1993 SC with the Steward Observatory 1.5-m telescope near Mt. Bigelow, Arizona and the Lunar and Planetary Laboratory CCD on 8 October

Visible and Infrared Photometry of Six Centaurs

Abstract We present infrared ( JHK ) and visible ( VRI ) observations of the Centaurs 2060 Chiron, 5145 Pholus, 7066 Nessus, 1995 DW 2 , 1995 GO, and 1997 CU 26 . These are combined whenever possible

The luminosity function of dwarf galaxies in four spiral-rich clusters

We measure luminosity functions in the cores of four spiral-rich, poor clusters of galaxies at median redshift $z = 0.016$. In the red magnitude range -14 < M_R < -10, our data imply that the

Periodic variations in the activity of Comet P/Halley during the 1985/1986 apparition

A search for periodic variation in the production of gas and dust by Comet Halley has been performed using narrowband photometric measurements from four sites - Lowell Observatory, Mauna Kea

A CCD portrait of Comet P/Tempel 2

The development of activity in Comet P/Tempel 2 is studied from aphelion (R = 4 AU) to perihelion (R = 1.4 AU) using extensive time-series CCD photometry and CCD spectra. The comet undergoes a

Short-Period Comets: Primordial Bodies or Collisional Fragments?

Modeling results show that collisions among Edgeworth-Kuiper Belt Objects (EKOs), a vast swarm of small bodies orbiting beyond Neptune, have been a major process affecting this population and its

Mechanical and geological effects of impact cratering on Ida

Asteroids respond to impact stresses differently from either laboratory specimens or large planets. Gravity is typically so small that seismic disturbances of a few cm s−1can devastate unconsolidated
