Notes. Results and statistical uncertainties (“Stat.” row) are given as median values and 1σ confidence limits, which are derived through a Monte Carlo simulation. The Galactic coordinate system is introduced in Fig. 3. Plane-crossing quantities are labeled by the subscript “p” and are based on all orbits that crossed the Galactic plane within twice the estimated stellar lifetime to account for the star’s finite age (for HVS 3 this limit is set to 200 Myr, see text for details). The Galactic rest-frame velocity vGrf = (vx2 + vy2 + vz2)1/2, the local Galactic escape velocity vesc, the Galactocentric radius r = (x2 + y2 + z2)1/2, the ejection velocity vej (defined as the Galactic rest-frame velocity relative to the rotating Galactic disk), and the flight time τflight are listed in addition to Cartesian positions and velocities. The probability Pb is the fraction of Monte Carlo runs for which the star is bound to the Milky Way.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
