Usage Examples English
- Preliminary astrometric measurements made with the Hipparcos space probe suggested the planet has an orbital inclination of 164.0° and a mass 15 times that of Jupiter, which would make the object a brown dwarf.
- Using astrometric data taken from the U.S. Naval Observatory Robotic Astrometric Telescope (URAT) combined with previously collected data from the Hipparcos mission, and the newer Gaia EDR3 data release, a group of scientists at the United States Naval Observatory believe they have, with high formal confidence levels, confirmed the presence of a long-period exoplanet orbiting Epsilon Eridani.
- Preliminary astrometric measurements suggested that the orbital inclination is 170.3°, yielding an object mass of 38 times that of Jupiter, which would make it a brown dwarf.
- To correct for this effect, and so determine the true mass of an extrasolar planet, radial-velocity measurements can be combined with astrometric observations, which track the movement of the star across the plane of the sky, perpendicular to the line-of-sight.
- ALMA and astrometric measurements may show orbital motion.
- V357 Carinae is an astrometric binary, meaning its motion in the sky implies orbital motion about an invisible companion.
- 'BD +38 3491' is the 'B' component's designation in the Bonner Durchmusterung astrometric star catalogue.
- The Hipparcos catalogue identified Sigma Aquarii as a possible astrometric binary with an orbital period of 654 days.
- Astrometric measurements are used by astrophysicists to constrain certain models in celestial mechanics.
- Astrometric solving or Plate solving or Astrometric calibration of an astronomical image is a technique used in astronomy and applied on celestial images.
- The astrometric observations by the Hipparcos spacecraft detected a significant acceleration in the proper motion of AZ Phoenicis, indicating it is an astrometric binary.
- Michael Perryman is a British astronomer, known for his work leading the Hipparcos and Gaia space astrometric projects.
- This object was flagged as an astrometric binary based on proper motion measurements made from the Hipparcos spacecraft.
- The European Space Agency's astrometric satellite Gaia, launched in 2013, can approximate star positions to 7 microarcseconds (µas).
- In 2021, astrometric observations revealed the true mass of Iota Draconis b to be 16.4 [...].
- In 2018, Hubble astrometric observations revealed the true mass of Gamma Cephei Ab to be 9.4 [...].
