چکیده

With Gaia’s first data release comes a large amount of new data on stars in the Milky Way. We were interested in a subset of these that were cross referenced with the Tycho-2 catalogue. In this project, we look at two ways of analyzing the data spatial correlation functions and velocity profiles. To find a velocity profile, we looked at a subset of stars along the sun to galactic center line to determine their velocities and distance from center of the galaxy. We found a loose correlation between distance and velocity. For the spatial correlation, we compute the two point correlation function of the data set and found that stars cluster more at smaller scales as expected.

The rotation-metallicity relation for the Galactic disk as measured in the Gaia DR1 TGAS and APOGEE data

Aims. Previous studies have found that the Galactic rotation velocity-metallicity (V-[Fe/H]) relations for the thin and thick disk populations show negative and positive slopes, respectively. The first Gaia data release includes the Tycho-Gaia Astrometric Solution (TGAS) information, which we use to analyze the V-[Fe/H] relation for a strictly selected sample with high enough astrometric accura...

Gaia Data Release 1 - Reference frame and optical properties of ICRF sources

Context. As part of the data processing for Gaia Data Release 1 (Gaia DR1) a special astrometric solution was computed, the so-called auxiliary quasar solution. This gives positions for selected extragalactic objects, including radio sources in the second realisation of the International Celestial Reference Frame (ICRF2) that have optical counterparts bright enough to be observed with Gaia. A s...

Detection of a Dearth of Stars with Zero Angular Momentum in the Solar Neighbourhood

We report on the detection in the combined Gaia-DR1/RAVE data of a lack of disk stars in the solar neighbourhood with velocities close to zero angular momentum. We propose that this may be caused by the scattering of stars with very low angular momentum onto chaotic, halo-type orbits when they pass through the Galactic nucleus. We model the effect in a Milky-Way like potential and fit the resul...

Grids of synthetic spectra for the GAIA mission

Two sets of grids of Kurucz ATLAS 9 model spectra are presented. The first one covers the GAIA spectral interval, while the second one which is still being computed covers the whole range from 2500 – 10500 Å. Both grids include parameters needed for realistic spectral simulation, e.g. stellar rotation and are computed at R = 20000 and lower spectral resolutions. They can be useful for preparati...

On the accuracy of GAIA radial velocities

We have obtained 782 real spectra and used them as inputs for 6700 automatic crosscorrelation runs to investigate GAIA potential in terms of radial velocity accuracy. We have explored the dispersions 0.25, 0.5, 1 and 2 Å/pix over the 8490–8740 Å GAIA range. We have investigated late-F to early-M stars (constituting the vast majority of GAIA targets), slowly rotating (< Vrot sin i > = 4 km sec )...
