We present star count data from the Sloan Digital Sky Survey for 5.8 × 105 stars brighter than g' = 21 mag over 279 deg2 in two samples north and south of the Galactic plane. Using these high-latitude (49° < |b| < 64°) star counts we determine the Sun's distance from the Galactic midplane to be 27 ± 4 pc and the scale height of the old thin disk to be 330 ± 3 pc. Because of the photometric accuracy and large area sky coverage of these data, the color-magnitude diagram clearly reveals a… 
The Milky Way Tomography with SDSS. I. Stellar Number Density Distribution
Using the photometric parallax method we estimate the distances to ~48 million stars detected by the Sloan Digital Sky Survey (SDSS) and map their three-dimensional number density distribution in the
Studying the populations of our Galaxy using the kinematics of sdB stars
We have analysed the kinematics of a sample of 114 hot subdwarf stars. For 2/3 of the stars, new proper motions, spectroscopic and photometric data are presented. The vast majority of the stars show
Milky Way Tomography with K and M Dwarf Stars: the Vertical Structure of the Galactic Disk
We use the number density distributions of K and M dwarf stars with vertical height from the Galactic disk, determined using observations from the Sloan Digital Sky Survey, to probe the structure of
Constraining the Galactic structure parameters with the XSTPS-GAC and SDSS photometric surveys
Photometric data from the Xuyi Schmidt Telescope Photometric Survey of the Galactic Anticentre (XSTPS-GAC) and the Sloan Digital Sky Survey (SDSS) are used to derive the global structure parameters
Galactic structure studies with BATC star counts
We report the first results of star counts carried out with the National Astronomical Observatories (NAOC) 60=90 cm Schmidt Telescope in 15 intermediate-band filters from 3000 to 10 000 A in the BATC
8 Star Counts and Nature of the Galactic Thick Disk
Modern star counts at high Galactic latitudes played a major role in revealing the existence of a thick disk as the third stellar component of the Milky Way Galaxy in addition to the old thin disk
A Spectroscopic Study of the Ancient Milky Way: F- and G-Type Stars in the Third Data Release of the Sloan Digital Sky Survey
We perform an analysis of spectra and photometry for 22,770 stars included in the third data release (DR3) of the Sloan Digital Sky Survey (SDSS). We measure radial velocities and, based on a
The Millennium Galaxy Catalogue: star counts and the structure of the Galactic stellar halo
We derive a star catalogue generated from the images taken as part of the � 37.5 deg 2 Millennium Galaxy Catalogue. These data, alone and together with colours gained from the Sloan Digital Sky
The size and shape of the Milky Way disc and halo from M-type brown dwarfs in the BoRG survey
We have identified 274 M-type Brown Dwarfs in the Hubble Space Telescope's Wide Field Camera 3 (WFC3) pure parallel fields from the Brightest of Reionizing Galaxies (BoRG) survey for high redshift
Vertical distribution of Galactic disk stars ? II. The surface mass density in the Galactic plane
High resolution spectral data of red clump stars towards the NGP have been obtained with the high resolution spectrograph Elodie at OHP for Tycho-2 selected stars. Combined with Hipparcos local


Identification of a-colored stars and structure in the halo of the Milky Way from Sloan digital sky survey commissioning data
A sample of 4208 objects with magnitude 15 < g* < 22 and colors of main-sequence A stars have been selected from 370 deg2 of Sloan Digital Sky Survey (SDSS) commissioning observations. The data is
The displacement of the sun from the galactic plane using IRAS and faust source counts
I determine the displacement of the Sun from the Galactic plane by interpreting IRAS point-source counts at 12 and 25 microns in the Galactic polar caps using the latest version of the SKY model for
Predicted star counts in selected fields and photometric bands Applications to galactic structure, the disk luminosity function, and the detection of a massive halo
Tables are presented of predicted star counts in 17 selected directions on the sky as a function of apparent B, V, R, and I magnitudes and absolute visual magnitudes calculated from the
Comparisons of a Galactic Kinematic Model with Two Proper-Motion Surveys in the Vicinity of the North Galactic Pole
A Galactic kinematic model has been constructed for modeling the distributions of magnitude, colors, and proper motions. In addition, we have developed a star-count analysis algorithm, which uses all
A survey of proper motion stars. IX - The galactic halo's metallicity gradient
Using data already presented for a survey of proper motion stars and the Bahcall, Schmidt, and Soneira (1983) model of the Galaxy, Galactic orbital parameters are computed, including planar and
