Sentences with phrase «new velocity measurements»

Not exact matches

At one point Fizeau's measurement of the velocity of light in water seemed a conclusive refutation of the corpuscular theory of light; but the latter returned, in a new form, in Einstein's theory of photons.

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.

These two figures show the internal waves at Dongsha Island on April 23, 2010, as seen by the radar on TerraSAR - X in its conventional mode of operation (left) and in the experimental new mode that permits direct velocity measurements (right), with the measured surface velocities shown in color.

By combining the new observations with the measurements from 1993, the team deduced the object's mass, distance, and velocity.

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.

The new radial velocity measurements are now available for download on our website.

We present new mass measurements of three of the planets in the Kepler - 20 system facilitated by 104 radial velocity measurements from the HARPS - N spectrograph and 30 archival Keck / HIRES observations, as well as an updated photometric analysis of the Kepler data and an asteroseismic analysis of the host star (MStar = 0.948 + -0.051 Msun and Rstar = 0.964 + -0.018 Rsun).

The planets are amenable to mass measurement by precision radial velocity measurements, and therefore K2 - 138 could represent a new benchmark systems for comparing radial velocity and TTV masses.

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).

With a (revised) diameter of 2.63 ± 0.11 times that of Earth, the mass of the planet was derived from radial - velocity measurements using the ESO 3.6 - meter telescope and its HARPS spectrograph)(ESO press release; Bean et al, 2010; Charbonneau et al 2009; Geoffrey Marcy, 2009; Rogers and Seager, 2009; Dennis Overbye, New York Times, December 16, 2009; and Ivan Seminuik, New Scientist, December 16, 2009).

To determine how much ice and snowfall enters a specific ice shelf and how much makes it to an iceberg, where it may split off, the research team used a regional climate model for snow accumulation and combined the results with ice velocity data from satellites, ice shelf thickness measurements from NASA's Operation IceBridge — a continuing aerial survey of Earth's poles — and a new map of Antarctica's bedrock.
