Exempel på hur man kan använda ASTROMETRIC i en mening

• The United Kingdom also hosts the self-styled Spaceguard Centre which conducts astrometric research (MPC code J26) and is open to the general public daily, but it is not affiliated with or supported by any public body.
• Relying upon high-powered terrestrial radars (of up to one megawatt), radar astronomy is able to provide extremely accurate astrometric information on the structure, composition and movement of Solar System objects.
• Different sets of astrometric observations lead to different mass determinations; the biggest problem is accounting for the aggregate perturbations caused by all of the smaller asteroids.
• Celestia does not include any stars that are more than a few thousand light-years from the Sun because the parallaxes of more distant stars are too small to be accurately measured by the Hipparcos astrometric satellite.
• Observatories, telescopes and surveys that report astrometric observations of small Solar System bodies to the Minor Planet Center receive a numeric or alphanumeric MPC code such as 675 for the Palomar Observatory, or G96 for the Mount Lemmon Survey.
• The Circulars contain astrometric observations, orbits and ephemerides of minor planets, comets and certain natural satellites.
• While at Sproul Observatory, he made astrometric measurements of Barnard's Star and in the 1960s reported a periodic "wobble" in its motion, apparently due to planetary companions.
• The Jewel Box as a star cluster was first found by Nicolas Louis de Lacaille while doing astrometric observations for his 1751–1752 southern star catalogue Cœlum Australe Stelliferum at the Cape of Good Hope in South Africa.
• The other was an astrometric station in Mykolaiv – a former observatory of the Department of the Navy, (today's Nikolaev Astronomical Observatory).
• Subsequent astrometric studies have found differing results; a 2022 study found inclinations consistent with aligned orbits, while a 2023 study again found misaligned orbits.
• Phecda is also an astrometric binary: the companion star regularly perturbs the Ae-type primary star, causing the primary to wobble around the barycenter.
• NOFS has used NPOI to conduct a wide and diverse series of scientific studies, beyond just the study of absolute astrometric positions of stars,; additional NOFS science at NPOI includes the study of binary stars, Be Stars, Oblate stars, rapidly rotating stars, those with starspots, and the imaging of stellar disks (the first in history) and flare stars.
• NOVAS is an integrated package of subroutines for the computation of a wide variety of common astrometric quantities and transformations, in Fortran and C, from the U.
• The Hubble Space Telescope has used a different method to derive the distance to GK Persei using nebular expansion velocity and compares that with its own astrometric parallax calculation.
• Omicron Aurigae, Latinized from ο Aurigae, is the Bayer designation for an astrometric binary star system in the northern constellation of Auriga.
• These parallaxes are subject to inaccuracies, as changness in VV Cephei A's brightness can cause a measurable astrometric shift and therefore affect the parallax measurement.
• 5 milliarcseconds per year are given as derived from a comparison with the Astrographic Catalogue (AC 2000) and 143 other ground-based astrometric catalogues, all reduced to the Hipparcos celestial coordinate system.
• Images will be available in two forms: Raw Snaps, or data straight from the camera, and Single Visit Images, which have been processed and include instrumental signature removal (ISR), background estimation, source detection, deblending and measurements, point spread function estimation, and astrometric and photometric calibration.
• In addition to astrometric studies (such as for Space Situational Awareness, SDSS and SST), research on this telescope includes the study of blue and K-Giant stars, celestial mechanics and dynamics of multiple star systems, characterizations of artificial satellites, and the astrometry and transit photometry of exoplanets.
• Projects are now beginning that will use interferometers to search for extrasolar planets, either by astrometric measurements of the reciprocal motion of the star (as used by the Palomar Testbed Interferometer and the VLTI) or through the use of nulling (as will be used by the Keck Interferometer and Darwin).
