Astrometric orbit of HR 6046
The previously known, 6yr single-lined spectroscopic binary HR 6046 has been speculated in the past to contain a compact object as the secondary. A recent study has redetermined... -
Radio star proper motions
We have used the Very Large Array, linked with the Pie Town Very Long Baseline Array antenna, to determine astrometric positions of 46 radio stars in the International Celestial... -
Fourth VLBA calibrator survey: VCS4
This paper presents the fourth extension to the VLBA Calibrator Survey, containing 258 new sources not previously observed with very long baseline interferometry (VLBI). This... -
Coma Berenices astrometric catalogue
A catalogue of stellar positions and proper motions down to the 14th photographic magnitude in the area of the open cluster in Coma Berenices is compiled from data of 12... -
Sirius photographic observations
A series of photographic observations on the components of Sirius was carried out in the years 1976-1986 at the Bosscha Observatory. We present the analysis and the results of... -
Saturn's satellites in 1995/97
In this paper, we publish measurements of 1514 positions of the major satellites of Saturn made in 1995 and 1997 using CCD detectors attached to the 1-metre Jacobus Kapteyn... -
CPASJ2 catalogue
According to the cooperation between Beijing, San Juan and La Plata Astronomical Observatories, the photoelectric astrolabe Mark II(PAII) of the Beijing Astronomical Observatory... -

VVV tiles b248 and b333 proper motions
We use near-infrared, ground-based data from the VISTA Variables in the Via Lactea (VVV) survey to indirectly extend the astrometry provided by the Gaia catalog to objects in... -
Improving the open cluster census. II.
Data from the Gaia satellite is revolutionising our understanding of the Milky Way. With every new data release, there is a need to update the census of open clusters. We aim to... -
Improving the open cluster census. I.
The census of open clusters in the Milky Way is in a never-before seen state of flux. Recent works have reported hundreds of new open clusters thanks to the incredible... -
Saturnian satellites in the Gaia ref. frame
We present a remeasurement of old photographic plates, providing important raw data for dynamical studies of the Saturnian satellite system. The unprecedentedly accurate... -
Determining true mass of RV exoplanets with Gaia
Mass is one of the most important parameters for determining the true nature of an astronomical object. Yet, many published exoplan- ets lack a measurement of their true mass,... -
Galaxies in the Tycho-2 catalogue
The accuracy of the link of the proper motion system of astrometric satellite missions like AMEX and GAIA is discussed. Monte-Carlo methods were used to simulate catalogues of... -
The AMIGA project. Revised positions for CIG galaxies
We present revised positions for the 1051 galaxies belonging to the Karachentseva Catalog of Isolated Galaxies (CIG, Cat. ). New positions were calculated by applying SExtractor... -
Extension of ICRF for selected areas down to V=16
A catalogue of accurate positions and proper motions for 678,828 objects is provided. Objects are within areas of special astronomical interest, containing extragalactic radio... -
180MHz Murchison Commissioning Survey (MWACS)
The Murchison Widefield Array Commissioning Survey (MWACS) is a ~6100deg^2^ 104-196MHz radio sky survey performed with the Murchison Widefield Array during instrument... -
GLEAM sources ionospheric position shifts
Nearly 200 hours of observing with the Murchison Widefield Array (MWA) radio telescope during the Galactic and Extra-galactic All-sky MWA (GLEAM) survey were used to assemble... -
USNO Galilean observations
The New Astrometric Reduction of Old Observations (NAROO) program is dedicated to the measurement of astrophotographic plates and the analysis of old observations for scientific...
