Sentences with phrase «velocity measurements taken»

Not exact matches

Fellow IoA astronomer Floor van Leeuwen agrees, adding that individual velocity measurements of the stars will resolve the question definitively, but probably not before 10 to 15 years from now, when new satellites take to the skies.

Vogt and Butler's team found the new planet by combining 119 star velocity measurements from HARPS with 122 measurements taken with a similar instrument called HIRES, which is mounted on the 10 - metre Keck 1 telescope in Hawaii.

HARPS allows for measurements of radial velocities of stars, which can be affected by the presence of nearby planets, to be taken with the highest accuracy currently available.

The researchers took measurements of small - scale temperature and velocity fluctuations, to measure the diapycnal movements in the Antarctic Circumpolar Current (ACC) across the Drake Passage region of the Southern Ocean.

Laughlin says it's frustrating that the most interesting planets — small ones like Earth — are so challenging to detect: «You have to get tons and tons and tons of velocity measurements over many years, and then you really, really have to take extreme care — as this Tuomi et al. paper does — to get rid of all the systematic noise.»

Forensic meteorologists may also take their own measurements, such as wind velocity.

Our barycentric radial velocities, derived from observations taken at the KPNO 2.1 meter telescope, differ from... ▽ More We demonstrate the ability to measure precise stellar barycentric radial velocities with the dispersed fixed - delay interferometer technique using the Exoplanet Tracker (ET), an instrument primarily designed for precision differential Doppler velocity measurements using this technique.

By carefully combining position measurements from digital archives with newer positions measured from images taken during the course of the Pan-STARRS1 survey, they were able to derive the tangential component of the star's velocity (across our line of sight).

The researchers took high - resolution mean and fluctuating velocity and density field measurements in an RM flow, which was shocked and reshocked, to understand production and dissipation in a two - fluid, developing turbulent flow field.

You have to get tons and tons and tons of velocity measurements over many years, and then you really, really have to take extreme care — as this Tuomi et al. paper does — to get rid of all the systematic noise.»

It can be simply measured using dynamometry by taking multiple measurements in the same dynamometer of the same joint angle movement, at different angular velocities.

For thirty years, he had taken tens of thousands of measurements of variously shaped surfaces moving at different angles through the air using a «whirling arm,» a long pole that extended horizontally from a fixed vertical pole and spun at a preset velocity, a device originally developed to test the flight of cannonballs.

In contrast, Joughin and Tulaczyk's analysis takes advantage of the much - expanded database available from ice - flow velocity measurements obtained using Interferometric Synthetic Aperture Radar.
