The orbit of the LMC is close to being polar and thus the Galactic latitude of an LMC runaway star approximately determines its kinematics. An SFR of 0.2 MWe model the properties of stars ejected from binary systems in which one component goes SN using the Probability density distribution in velocity–colour space at the time of ejection from the progenitor binary of the runaways produced by our binary evolution grid assuming LMC metallicity Probability density distribution in velocity–colour space at the time of ejection from the progenitor binary of the runaways produced by our binary evolution grid assuming LMC metallicity The binary origin of the runaway stars that escape the LMC influences their subsequent evolution because prior to ejection more than 90 per cent experience mass transfer from the primary. Of the two outliers, Sk-67 2 is suggested as a candidate HVS based on … In fact, the majority of our runaways would be classed as walkaways, with 65 per cent of runaways having ejection velocities less than 10 km s −1, and hence indistinguishable from the disc population.

The bins are defined by a 100 × 100 grid over the range of each plot. (We can evaluate whether the observed HVSs originate in the LMC, whilst being agnostic about the mechanism, by considering the runaway stars in our model to be tracer particles of the kinematic distribution of stars ejected from the LMC. The Runaways call the cops, but receive no help (partly because the cops think it's a crank call, partly because Alex's parents have agents in the LAPD). January.
