Comparison of the first results from the Hipparcos star mappers with the Hipparcos Input Catalogue
Preliminary positions and magnitudes derived from the analysis of 12 weeks of observations from the Hipparcos star mappers are systematically compared with the various sources of ground-based data used in the Hipparcos Input Catalogue. These comparisons allow to cross-check the accuracies claimed by the various sources of ground-based data and by the analysis method of star mapper data. The par...
متن کاملPhotocentre displacement of minor planets: analysis of Hipparcos astrometry
We present a study of the phase effect (or photocentre offset) on the astrometry of minor planets. Analysis of the high precision Hipparcos observations of the largest asteroids shows the validity of the model. Minor planets Ceres, Pallas, Vesta and Iris show a brightness distribution close to the lunar scattering properties, while Juno and Hebe are found to be more uniformly bright objects. Fo...
متن کاملAstrometry of Galactic Star-Forming Region G48.61+0.02 with VERA
We performed the astrometry of H2O masers in the Galactic star-forming region G48.61 + 0.02 with the VLBI Exploration of Radio Astrometry (VERA). We derived a trigonometric parallax of 199 ± 7 μas, which corresponds to a distance of 5.03 ± 0.19 kpc. The distance to G48.61 + 0.02 is about a half of its far kinematic distance, which was often assumed previously. This distance places G48.61 + 0.02...
متن کاملThe recent star formation history of the Hipparcos solar neighbourhood
We use data from the Hipparcos catalogue to construct colour-magnitude diagrams for the solar neighbourhood, which are then treated using advanced Bayesian analysis techniques to derive the star formation history, SFR(t), of this region over the last 3 Gyr. The method we use allows the recovery of the underlying SFR(t) without the need of assuming any a priori structure or condition on SFR(t), ...
متن کاملDetection of Planetary Transits of the Star HD 209458 in the Hipparcos Data Set.
A search of the Hipparcos satellite photometry data for the star HD 209458 reveals evidence for a planetary transit signature consistent with the planetary properties reported by Henry et al. and Charbonneau et al. and allows further refinement of the planet's orbital period. The long time baseline (about 2926 days or 830 periods) from the best Hipparcos transit-like event to the latest transit...
