radial velocity造句
1 At apogee its radial velocity reaches zero, so it once again has a purely horizontal velocity.
2 The new planet was discovered using what is called the "radial velocity method" which involves detecting small wobbles in a star caused by a planet as it tugs on its sun.
3 The new planets were detected by measuring "radial velocity, " or how fast a star wobbles depending on the gravitational pull from nearby planets.
4 This common method in the planet-hunting world, called radial velocity, requires extremely precise measurements to detect a planet's gravitational pull on a nearby star.
5 The radial velocity method, which looks for changes in a star's velocity toward or away from Earth triggered by a planet's orbit around that star.
6 The value of radial velocity is less than the others, and only changes acutely in the vortex chamber.
7 This discovery was made by The High Accuracy Radial Velocity Planet Searcher (HARPS), which is installed at the European Southern Observatory's La Silla Observatory in Chile.
8 Even a low radial velocity will lead to a severe distortion.
9 But in recent years astronomers have used radial velocity to find or confirm a number of planets down to a few times Earth's mass.
10 Radial velocity, also known as the Doppler wobble technique, involves searching for wobbles in a star's light that indicate the gravitational pull of an orbiting planet.
11 The radial velocity and Doppler width distribution of belted atomic vapor are given.
12 The tracking filter incorporating the radial velocity and varying sampling interval concept should have a practical application in engineering.
13 Using the concepts of radial velocity and transversal velocity in polar coordinate system, a problem of pursuant trajectory in kinematics is solved.
14 Mayor and colleagues used the High Accuracy Radial velocity Planet Searcher or HARPS, a telescope at La Silla observatory in Chile, to find the planets.
15 Radial velocity is a planet-hunting technique that looks for wobbles in a star's light, which can indicate the gravitational tugs of orbiting worlds.
16 At any point on the ellipse between apogee and perigee a spacecraft will have both a horizontal and a radial velocity.
17 Only 9 other red dwarfs are known to have planetary companions, and these were all discovered through the radial velocity technique.
18 Just to be sure, the team followed up with six radial velocity observations at the Keck I telescope in Hawaii.
19 The primary experiments on the retrieval of the wind vector fields from the Doppler radial velocity to modify the initial forecast fields are carried out, and some conclusions are obtained.
20 Axial velocity presents a saddle-shaped distribution, and with a good axial symmetry except the inlet position. Radial velocity is less an order of magnitude with a non-axisymmetric distribution.
21 Astronomers found the planet using the European Southern Observatory's High Accuracy Radial velocity Planet Searcher, or HARPS, instrument in Chile.
22 But to get the planet's mass, astronomers normally need to follow up with time-consuming radial velocity observations at some of the planet's biggest telescopes.
23 But the 50 new planets announced in Wyoming were discovered from the ground with a device called the High Accuracy Radial velocity Planet Searcher, or HARPS.
24 The wind field retrieval data are obtained by plied MUSCAT technique to transact the rude radial velocity data which were observed by dual-Doppler radar volume scans.
25 It is thought that the velocity vector distribution in oil film stratum is composed of radial velocity and circumferential velocity and is the dominant factor influencing the heat convection.
26 Finally, scientists measure the star's wobble due to the planet's gravitational tug, known as the radial velocity.
27 The planetary treasure trove was found using an instrument called HARPS—short for High Accuracy Radial Velocity Planet Searcher—at the European Southern Observatory's La Silla facility in Chile.
