Sentences with phrase «known proper motion»

The remaining examples are mostly named after astronomers, the best known are probably Barnard's Star (which has the highest known proper motion of any star and is thus notable even though it is far too faint to be seen with the naked eye), Kapteyn's Star and recently Tabby's Star.

Massari and the team from the Kapteyn Institute are looking forward to extending their sample of stars outside the Milky Way with known proper motion after the new Gaia data release early next year.

Not exact matches

However, measuring the movement in the plane of the sky, what is known as the proper motion, is much more difficult.

We identified two high proper motion objects with the very red (W1 - W2) colors characteristic of T dwarfs, one being the known T7.5 dwarf GJ 570D.

We identify PSO J060.3200 +25.9644 (near - infrared spectral type L1) and PSO J077.1033 +24.3809 (L2) as new members of Taurus based on their VL - G gravity classifications, the consistency of their photometry and proper motions with previously known Taurus objects, and the low probability of contamination by field objects.

Based on knowing these common proper motions and radial velocities, Alpha Centauri will continue to gradually brighten, passing just north of the Southern Cross or Crux, before moving northwest and up towards the present celestial equator and away from the galactic plane.

The distances of individual stars in a moving group may be determined if their radial velocities and proper motions are known (see below Stellar motions) and if the exact position of the radiant is determined.

Trying to lift weights that you know you're not capable to lift with proper form will limit your range of motion, decrease the effectiveness of the exercise and increase your risk of injury.

In that context, we can differentiate between positive failure — the point when you can no longer perform another rep with proper form and full range of motion and negative, or total failure — the point when after a few forced reps, you can't even lower the weight without assistance from a spotter anymore.

You probably won't be able to complete 50 consecutive reps with proper form and full range of motion, but that's Ok — take as many short breaks as you need but make sure you hit 50 reps with full range of motion and a hard squeezing contraction at the top, no matter what.

The most common examples are positive failure, which happens when you've reached failure right before hitting the top part of the motion and thereby can no longer perform another rep with proper form without a spotter's assistance, and negative failure or total failure, which refers to failing in the bottom part of the motion.
