The Proper Motion of the Arches Cluster with Keck Laser-guide Star Adaptive Optics
We present the first measurement of the proper motion of the young, compact Arches cluster near the Galactic center from near-infrared adaptive optics (AO) data taken with the recently commissioned laser-guide star (LGS) at the Keck 10 m telescope. The excellent astrometric accuracy achieved with LGS-AO provides the basis for a detailed comparison with VLT/NAOS-CONICA data taken 4.3 yr earlier....
متن کاملThe proper motion and energy distribution of the isolated neutron star RX J0720.4-3125
ESO 4m class telescope and VLT deep imaging of the isolated neutron star RXJ0720.4-3125 reveals a proper motion of μ = 97 ± 12mas/yr and a blue U-B color index. We show that a neutron star atmosphere model modified to account for a limited amount of hydrogen on the star’s surface can well represent both the optical and X-ray data without invoking any additional components. The large proper moti...
متن کامل0 The Proper Motion , Parallax , and Origin of the Isolated Neutron Star RX J 185635 - 3754
The isolated neutron star RX J185635-3754 is the closest known neutron star to the Sun. Based on HST WFPC2 obervations over a 3 year baseline, I report its proper motion (332±1 mas yr at a position angle of 100.3±0.1) and parallax (16.5±2.3 mas; 61 pc). This proper motion brings the neutron star from the general vicinity of the Sco-Cen OB association. For an assumed neutron star radial velocity...
متن کاملOn the Crab Proper Motion
Owing to the dramatic evolution of telescopes as well as optical detectors in the last 20 yrs, we are now able to measure anew the proper motion of the Crab pulsar, after the classical result of Wyckoff and Murray (1977) in a time span 40 times shorter. The proper motion is aligned with the axis of symmetry of the inner Crab nebula and, presumably, with the pulsar spin axis.
متن کاملProper motion in Cygnus A
Our recent VLBI observations of the prominent FR II radio galaxy Cygnus A with the EVN and the VLBA reveal a pronounced two-sided jet structure. from which we could derive the kinematics of the jet and counter-jet. On the jet side and on mas scales, the jet seems to accelerate from βapp ≈ 0.1 − 0.2 (Krichbaum et al. 1998) at core-separations near 1 mas to βapp ≈ 0.4 − 0.6 at r ≥ 4 mas (H0 = 100...
