velocity survey मीनिंग इन हिंदी

HD 154088 is also being observed under the Keck Eta-Earth radial velocity survey.
Radial velocity surveys found exoplanet orbits beyond 0.1 AU to be eccentric, particularly for large planets.
For a subsample of 6dF a peculiar velocity survey is measuring mass distribution and bulk motions of the local Universe.
This is the regime just fainter than the set of stars comprehensively surveyed for planets by the radial-velocity surveys, but brighter than those typically observed by most transit surveys.
When 54 Piscium B was directly imaged by NASA's Spitzer Space Telescope, it was shown that the brown dwarf had a projected separation of around 476 astronomical units from the primary star . 54 Piscium B was the first brown dwarf to be detected around a star with an already known extrasolar planet ( based on radial velocity surveys ).
