The distribution of nearby stars in phase space mapped by Hipparcos: I. The potential well and local dynamical mass
M. Crézé, E. Chereul, O. Bienaymé +1
Hipparcos data provide the first, volume limited and absolute magnitude limited homogeneous tracer of stellar density and velocity distributions in the solar neighbourhood. The den…
Structure and kinematical properties of the Galaxy at intermediate galactic latitudes
Devendra Ojha, Olivier Bienayme, Annie Robin +2
We have carried out a sample survey in UBVR photometry and proper motions in different directions in the Galaxy, as part of an investigation of galactic structure and evolution. Th…
How Do the Stellar Disc and Thick Disc Stop ?
Annie C. Robin, Michel Creze, Vijay Mohan
As part of a stellar population sampling program, a series of photometric probes at various field sizes and depths have been obtained in a low extinction window in the galactic ant…
Ubv CCD Standards Near 5C1 Radio Sources at Intermediate Galactic Latitude-I
V. Mohan, D. K. Ojha, O. Bienayme +9
We have been doing a photometric and astrometric sample survey programme on Schmidt plates in a few selected directions in the Galaxy with an aim to study galactic stellar populati…
