Abstract Photometric measurements of 33 transneptunian objects (TNOs) and Centaurs from the target list of the Herschel Key program ‘TNOs are cool’ are presented. Broadband filter observations of 5 Plutinos, 14 classical disk objects (CDOs), 5 scattered disk objects (SDOs), 5 detached disk objects (DDOs) and 4 Centaurs are used to determine absolute magnitudes, broadband colours and spectral gradients in the visible wavelength range. The diameters of the objects estimated with assumed average… Expand
Absolute magnitudes and phase coefficients of trans-Neptunian objects
Context: Accurate measurements of diameters of trans-Neptunian objects are extremely complicated to obtain. Thermal modeling can provide good results, but accurate absolute magnitudes are needed toExpand
"TNOs are Cool": A survey of the trans-Neptunian region. XIV. Size/albedo characterization of the Haumea family observed with Herschel and Spitzer
Context. A group of trans-Neptunian objects (TNOs) are dynamically related to the dwarf planet 136108 Haumea. Ten of them show strong indications of water ice on their surfaces, are assumed to haveExpand
Discovery of a Satellite of the Large Trans-Neptunian Object (225088) 2007 OR10
2007 OR10 is currently the third largest known dwarf planet in the trans-Neptunian region, with an effective radiometric diameter of ~1535 km. It has a slow rotation period of ~45 hr that wasExpand
Large size and slow rotation of the trans-Neptunian object (225088) 2007 OR10 discovered from Herschel and K2 observations
We present the first comprehensive thermal and rotational analysis of the second most distant trans-Neptunian object (225088) 2007 OR10. We combined optical light curves provided by the Kepler spaceExpand
The mass and density of the dwarf planet (225088) 2007 OR10
The satellite of (225088) 2007 OR10 was discovered on archival Hubble Space Telescope images and along with new observations with the WFC3 camera in late 2017 we have been able to determine theExpand


ESO large program on physical studies of Transneptunian Objects and Centaurs: Visible photometry – First results
We present the first results of BVRI photometry of Transneptunian Objects (TNOs) and Centaurs obtained through the ESO Large Program on physical studies of these icy bodies in the outer solar system.Expand
Multicolor photometry of trans-neptunian objects
Abstract We are continuing our photometric survey of the trans-neptunian and Centaur populations started in 1997. We report multicolor photometry for 17 objects. With these results combined withExpand
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 sampleExpand
ESO large program on Centaurs and TNOs: visible colors—final results
Abstract We report 43 new visible colors of Centaurs and TNOs, obtained at NTT and VLT telescopes under the “ESO large program on physical properties of Centaurs and TNOs.” Merging these newExpand
Visible and near-infrared colors of Transneptunian objects and Centaurs from the second ESO large program
Aims. We investigate color properties and define or check taxonomic classifications of objects observed in our survey. Methods. All observations were performed between October 2006 and September 2007Expand
TNOs are Cool: A Survey of the Transneptunian Region
Over one thousand objects have so far been discovered orbiting beyond Neptune. These trans-Neptunian objects (TNOs) represent the primitive remnants of the planetesimal disk from which the planetsExpand
Color Properties and Trends of the Transneptunian Objects
The color of transneptunian objects (TNOs) is the first and basic information that can be easily obtained to study the surface properties of these faint and icy primitive bodies of the outer solarExpand
The Color Distribution in the Edgeworth-Kuiper Belt*
In 1997 we began the Meudon Multicolor Survey of Outer Solar System Objects with the aim of collecting a large and homogeneous set of color data for trans-Neptunian objects (TNOs) and Centaurs. HereExpand
