Massive and luminous YSO IRAS 05361+3539 and its environment. A study of star formation in the parent cloud - I
A. Chakraborty, D. K. Ojha, B. G. Anandarao +1
Near-infrared photometry and narrow/broad-band imaging of the massive and luminous young stellar object IRAS 05361+3539 are presented. Imaging observations were made at Mt. Abu whi…
New surveys of UBV photometry and absolute proper motions at intermediate latitude
D. K. Ojha, O. Bienayme, V. Mohan +1
A photometric and proper motion survey has been obtained in 2 directions at intermediate latitude: (, ; ,$δ_{2000}=+49^\circ53'27…
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…
Kinematical Properties of the Thick Disk of the Galaxy
Devendra Ojha
We try here to find new constraints on thick disk population using samples at intermediate latitude and North Galactic Pole, which include photometry and proper motions. The algori…
Astrometric Plate Reduction with Orthogonal Functions and Milli-Arcseconds Accuracy in Deep Proper Motion Surveys
Devendra Ojha, Olivier Bienayme
We have been doing a sample survey in UBV photometry and proper motions as part of an investigation of galactic structure and evolution. The programme is based on Schmidt plates (f…
The Asymmetric Drift of the Thick Disk Population
Devendra Ojha, Annie C. Robin, Olivier Bienayme
We investigate the kinematics of the intermediate population using the photometric and astrometric sample surveys towards two opposite directions (galactic centre and anticentre) a…
