Sentences with phrase «proper motion measurements»
An independent Bayesian analysis from proper motion measurements results in a 87 % probability that this free - floating planet is a member of the 50 - 120 Myr old AB Doradus moving group, which strengthens the spectroscopic youth diagnosis.

By combining data from the Hubble Space Telescope and the Gaia mission, University of Groningen astronomers have been able to measure the proper motion of 15 stars in the Sculptor Galaxy, the first such measurement of stars in a small galaxy outside the Milky Way.
Those measurements, however, were not accurate enough to obtain parallax, and relied instead on tracking the star - forming region's so - called «proper motion» across the plane of the sky.
Finally, we present catalogs of Pan-STARRS1 proper motions for low - mass members of Taurus and Upper Scorpius with median precisions of $ \ approx $ 3 mas yr $ ^ -LCB--1 -RCB- $, including 67 objects with no previous proper motion and 359 measurements that improve on literature values.
These will allow very accurate measurements of the proper motions of the components and may give information on planets.
