Aims. We compile and analyze an extended database of light curve parameters scattered in the literature to search for correlations and study physical properties, including internal structure constraints. Methods. We analyze a vast light curve database by obtaining mean rotational properties of the entire sample, determining the spin frequency distribution and comparing those data with a simple model based on hydrostatic equilibrium. Results. For the rotation periods, the mean value obtained is… Expand
Light curves of ten Centaurs from K2 measurements
Abstract Here we present the results of visible range light curve observations of ten Centaurs using the Kepler Space Telescope in the framework of the K2 mission. Well defined periodic light curvesExpand
Lightcurves and Rotational Properties of the Pristine Cold Classical Kuiper Belt Objects.
We present a survey on the rotational and physical properties of the dynamically low inclination Cold Classical trans-Neptunian objects. The Cold Classicals (CCs) are primordial planetesimals andExpand
Short-term variability of a sample of 29 trans-Neptunian objects and Centaurs
Aims. We attempt to increase the number of trans-Neptunian objects (TNOs) whose short-term variability has been studied and compile a high quality database with the least possible biases, which mayExpand
Photometry and taxonomy of trans-Neptunian objects and Centaurs in support of a Herschel key program
Context. The investigation of Centaurs and trans-Neptunian objects (TNOs) provides essential information about the early conditions and evolution of the outer solar system. The radiometric techniqueExpand
Photometric and spectroscopic evidence for a dense ring system around Centaur Chariklo
In this work we aim to study if the variability in the absolute magnitude of Chariklo and the temporal variation of the spectral ice feature, even its disappearance in 2007, can be explained by anExpand
Rotational properties of the binary and non-binary populations in the Trans-Neptunian belt
We present results for the short-term variability of Binary Trans-Neptunian Objects (BTNOs). We performed CCD photometric observations using the 3.58 m Telescopio Nazionale Galileo, the 1.5 m SierraExpand
OSSOS XII: Variability studies of 65 Trans-Neptunian Objects using the Hyper Suprime-Cam

“TNOs are Cool”: A survey of the trans-Neptunian region - VI. Herschel/PACS observations and thermal modeling of 19 classical Kuiper belt objects
Trans-Neptunian objects (TNO) represent the leftovers of the formation of the Solar System. Their physical properties provide constraints to the models of formation and evolution of the variousExpand
Absolute colours and phase coefficients of trans-Neptunian objects: Correlations and Populations
The study of the visible colours of the trans-Neptunian objects opened a discussion almost 20 years ago which, in spite of the increase in the amount of available data, seems far from subside.Expand
Stellar occultations by Trans-Neptunian objects: From predictions to observations and prospects for the future
TLDR
Most of the aspects involved in the complex process to successfully observe occultations are reviewed, and some of the lessons learned may allow an increase in the success rate and scientific output of the occultation technique applied to TNOs, in the short-term future. Expand
