The relative astrometry for CHES can accurately measure micro-arcsecond level angular separation between one target star and 6-8 reference stars.

Chinese researchers have discovered a promising mass-gap black hole using radial velocity and astrometry methods. The study was published online in Nature Astronomy on Sept. 10, and was conducted ...

The first VERA Astrometry Catalog was published this year and includes data for 99 objects. Positioning indicates that Earth orbits the Galactic Center, where the black hole is located, at 227 km/s.

Astrometry and Photometry. When not performing OSETI observations, appropriately trained observers can make precise measurements of the position and magnitude of recently discovered or poorly observed ...

Astrometry, says Lindegren, “was not regarded as a field that would offer any great prospects for young scientists”. He eventually gave up on repairing the telescope, but never abandoned the ...

Researchers have previously used astrometry to measure the precise mass of planets found with the wobble method, but this is the first time the technique has been used to discover an extrasolar ...
