Transneptunian objects and Centaurs from light curves

  title={Transneptunian objects and Centaurs from light curves},
  author={R. Duffard and J. Ortiz and A. Thirouin and P. Santos-Sanz and N. Morales},
  journal={Astronomy and Astrophysics},
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

“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
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
