A mid-term astrometric and photometric study of Trans-Neptunian Object (90482) Orcus
J. L. Ortiz, A. Cikota, S. Cikota +7
From CCD observations of a fixed and large star field that contained the binary TNO Orcus, we have been able to derive high-precision relative astrometry and photometry of the Orcu…
Observation of light echoes around very young stars
J. L. Ortiz, B. E. K. Sugerman, I. de la Cueva +5
The goal of the paper is to present new results on light echoes from young stellar objects. Broad band CCD images were obtained over three months at one-to-two week intervals for t…
Water-ice driven activity on Main-Belt Comet P/2010 A2 (LINEAR) ?
F. Moreno, J. Licandro, G. -P. Tozzi +8
The dust ejecta of Main-Belt Comet P/2010 A2 (LINEAR) have been observed with several telescopes at the at the Observatorio del Roque de los Muchachos on La Palma, Spain. Applicati…
SAOLIM, a prototype of a low cost System for Adaptive Optics with Lucky Imaging
J. Aceituno, S. F. Sanchez, J. L. Ortiz +1
A prototype of a low cost Adaptive Optics (AO) system has been developed at the Instituto de Astrofisica de Andalucia (CSIC) and tested at the 2.2m telescope of the Calar Alto obse…
"TNOs are cool": A survey of the trans-neptunian region. II. The thermal lightcurve of (136108) Haumea
E. Lellouch, C. Kiss, P. Santos-Sanz +33
Thermal emission from Kuiper Belt object (136108) Haumea was measured with Herschel-PACS at 100 and 160 micrometers for almost a full rotation period. Observations clearly indicate…
"TNOs are Cool": A survey of the trans-Neptunian region I. Results from the Herschel Science Demonstration Phase (SDP)
T. G. Mueller, E. Lellouch, J. Stansberry +32
The goal of the Herschel Open Time Key programme "TNOs are Cool!" is to derive the physical and thermal properties for a large sample of Centaurs and trans-Neptunian objects (TNOs)…
