High tangential velocity of WISE 1828 +2650, characteristic of an old disk population, indicates possible age of WISE 1828 +2650 in the range 2 — 4 Gyr, leading to mass estimate of about 3 — 6 MJup.
The 2.56» / yr proper motion of PSO J043.5 +02 is the second highest among field T dwarfs, corresponding to an tangential velocity of 87 + / -8 km / s.
«You take a picture now, wait three years or more, and then take another picture to see how the stars have moved; that gives you the tangential velocity.»
We analyze the kinematics of ultracool dwarfs in our catalog and find evidence that bluer but otherwise generic late - M and L field dwarfs (i.e., not subdwarfs) tend to have higher tangential velocities compared to typical field objects.
Not exact matches
The transverse (or tangential) velocity, T, is given by T = V sin λ = 4.74 μ / p where p is the star's parallax in arc seconds.
By carefully combining position measurements from digital archives with newer positions measured from images taken during the course of the Pan-STARRS1 survey, they were able to derive the tangential component of the star's velocity (across our line of sight).
