oort constant मीनिंग इन हिंदी

उदाहरण वाक्य

1. Therefore, the Oort constants can tell us a great deal about motions in the galaxy.
2. So the Oort constants can tell us something about the mass density at a given radius in the disk.
3. A is the Oort constant describing the shearing motion and B is the Oort constant describing the rotation of the Galaxy.
4. A is the Oort constant describing the shearing motion and B is the Oort constant describing the rotation of the Galaxy.
5. This is remarkably close to the actual measured Oort constants and tells us that the solar neighborhood is roughly rotating with the same linear velocity.
6. The flat rotation curve serves as an intermediate step between the two rotation curves, and in fact gives the most reasonable Oort constants as compared to current measurements.
7. Thus, the Oort constants can be expressed in terms of the radial and transverse velocities, distances, and galactic longitudes of objects in our Galaxy-all of which are, in principle, observable quantities.
8. The non-circular velocities will introduce scatter around this line, but with a large enough sample the true function can be fit for and the values of the Oort constants measured, as shown in figure 2.
9. The Hipparcos satellite, launched in 1989, was the first space-based Gaia spacecraft, planned for launch in 2012, is an updated successor to Hipparcos; when it comes online the quality of available data should allow new levels of accuracy in measuring the Oort constants.
