The star has a proper motion of 0.422 arcseconds per year in a direction 114.1° from north.
He discovered 379 new variable stars andover 1000 stars of high proper motion.
The two stars have the same proper motion, so they may be physically associated.
It is moving further from the Sun with a radial velocity of +28 km/s andhas a relatively high proper motion.
Controale May: arrow keys for proper motion and Space with Arrow Up/ Down to a Jump.
As of 1970, this star is separated by 737.9 arc seconds from the AB pair andthey share a common proper motion.
The two stars share a common proper motion and hence are probably gravitationally bound to each other.
Edmond Halley, comparing his observations with Ptolemy's catalog,discovers the proper motion of some"fixed" stars.
It is believed that the proper motion of the central star can be traced back to the Orion's Belt area.
Gaia Data Release 2 discovered a star with the same proper motion and parallax as Rho Phoenicis.
It has a relatively high proper motion, advancing across the celestial sphere at the rate of 0.201 arc seconds per year.
However, it has two companions that share a common proper motion through space with HD 4391.
The proper motion of a runaway star often points exactly away from a stellar association, of which the star was formerly a member, before it was hurled out.
Some researchers have reported more detailed kinematical features, such as the proper motion of the hotspots in the lobes.
To be specific about this, the proper motion of Sirius is estimated to be in the range of 1.21 arc-seconds per year about 1 degree every 3000 years.
The plan involved measuring the apparent magnitude, spectral type,radial velocity, and proper motion of stars in 206 zones.
Although the two stars share a common proper motion, the significant differences in their estimated ages suggests that they may not be physically connected.
Was discovered in 1897 by Jacobus Kapteyn,the star with the highest known proper motion at the time of its discovery.
The proper motion of a bell and a telescope and the limitation of their wrap during the movement are performed by means of external(upper) rollers, rolling along the inner guides.
The radial velocity of the star andchanges in its position over time(proper motion) can be used to measure its velocity relative to the Sun.
It ensures the knee cap remains in its proper position, and distributes stress,lowering the risk of re-injury by guiding the knee cap into proper motion.
However, in 1918 the Dutch-American astronomer Adriaan van Maanen was able to measure the proper motion of stars in part of the Pleiades cluster by comparing photographic plates taken at different times.
Astronomers are able to determine if stars are members of a kinematic group because they share the same age, metallicity, andkinematics radial velocity and proper motion.
While comparing his results with those of Nicolas Louis de Lacaille he noted the high proper motion of Alpha Centauri and communicated these to Thomas Henderson at the Royal Observatory, Cape of Good Hope.
Since the two stars share a common proper motion across the celestial sphere, it is possible that Alpha Reticuli, rather than being solitary, may instead be the primary component of a binary star system with an orbital period of, at least, 60,000 years.
By comparing the photographic plates of the Pleiades cluster taken in 1918 with images taken in 1943,van Maanen was able to identify those stars that had a proper motion similar to the mean motion of the cluster, and were therefore more likely to be members.
Ursae Majoris has a magnitude 8.86 common proper motion companion with about half this star's mass at an angular separation of 122.5″ along a position angle of 303°, as of 2012.
