The ESA Gaia space astrometry mission will perform an all-sky survey of stellar objects complete in the nominal magnitude range G = [6.0 - 20.0]. The stars with G < 6.0, i.e. those visible to the unaided human eye, would thus not be observed by Gaia. We present an algorithm configuration for the Gaia on-board autonomous object observation system that makes it possible to observe very bright stars with G = [2.0-6.0). Its performance has been tested during the in-orbit commissioning phase… 
Enabling science with Gaia observations of naked-eye stars
An overview of the data products generated for G<6 stars and the potential scientific applications is presented, and how the Gaia survey could be enhanced by further exploiting the techniques developed is discussed.
Accurate Ground-based Astrometry of Naked-eye Stars: The United States Naval Observatory Bright-star Astrometric Database
We present the United States Naval Observatory (USNO) Bright-star Astrometric Database (UBAD), a current-epoch high-accuracy astrometric catalog. The catalog consists of 364 bright northern
The Gaia mission
Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric

The Gaia global astrometry mission is now entering its fourth year of routine science operations. With the publication of the first data release in September 2016, it has begun to fulfil its promise
The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet β Pictoris b from Combined Direct Imaging and Astrometry
We present new observations of the planet β Pictoris b from 2018 with the Gemini Planet Imager (GPI), the first GPI observations following conjunction. Based on these new measurements, we perform a
Gaia's potential for the discovery of circumbinary planets
The abundance and properties of planets orbiting binary stars – circumbinary planets – are largely unknown because they are difficult to detect with currently available techniques. Results from the
Classical Cepheid variable stars are crucial calibrators of the cosmic distance scale thanks to a relation between their pulsation periods and luminosities. Their archetype, δ Cephei, is an important
BRITE-Constellation High-Precision Time-Dependent Photometry of the Early O-Type Supergiant ζ Puppis Unveils the Photospheric Drivers of Its Small- and Large-Scale Wind Structures
From 5.5 months of dual-band optical photometric monitoring at the 1 mmag level, BRITE-Constellation has revealed two simultaneous types of variability in the O4I(n)fp star ζ Puppis: one single
Uniform Star Catalogue using GWKM Clustering for Application in Star Sensors
A novel algorithm of weighted k-means clustering with geodesic criteria is presented to generate a uniform database for a star sensor and it was found that the uniformity leads to a significant reduction of the probability of observing a large number of stars in all fields of view.


Science performance of Gaia, ESA’s space-astrometry mission
Gaia is the next astrometry mission of the European Space Agency (ESA), following up on the success of the Hipparcos mission. With a focal plane containing 106 CCD detectors, Gaia will survey the
Gaia's FPA: sampling the sky in silicon
ESA´s astrometry satellite Gaia is scheduled for launch in 2013. In a combination of outstanding hardware performance, autonomous object detection and sophisticated data processing, Gaia will chart
GAIA: Composition, formation and evolution of the Galaxy
The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012. GAIA will provide
Gaia broad band photometry
Aims. The scientific community needs to be prepared to analyse the data from Gaia, one of the most ambitious ESA space missions, which is to be launched in 2012. The purpose of this paper is to
Wide-angle astrometry with the Mark III stellar interferometer
Astrometric measurements made with the Mark III stellar interferometer on five nights in August-September 1988 yielded average formal 1-sigma errors for 12 FK5 stars of 6 mas in declination and 10

An overview of the 4MOST systems: optomechanical, control, data management and operations concepts; and initial performance estimates are provided.
Gaia: organisation and challenges for the data processing
Abstract Gaia is an ambitious space astrometry mission of ESA with a main objective to map the sky in astrometry and photometry down to a magnitude 20 by the end of the next decade. While the mission
Gaia: Object Detectability Near Bright Extended Sources
The impact of bright extended sources on the observation and detection of faint sources by Gaia has been studied. The effect has been characterized using the representative case of stars near the
Gaia Data Processing Architecture
The overall composition of the DPAC and the envisaged overall architecture of the Gaia data processing system are described and one of the nine, so-called, coordination units comprising the Gaia processing system is described.
The Gaia focal plane
The astronomic mission Gaia is a cornerstone mission of the European Space Agency, due for launch in the 2011 time frame. Requiring extremely demanding performance, Gaia calls for the development of
