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

TLDR
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

COLOR–INCLINATION RELATION OF THE CLASSICAL KUIPER BELT OBJECTS

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,
