Proper motions of stars in the region close to the Quintuplet cluster. Red-coloured diamonds denote hot star candidates we classified as being located in the GC, and blue cross-symbols denote those stars we classified as non-GC stars or stars with unknown status. The red arrows indicate the proper motions of our hot star candidates from Hosek et al. (2022). The arrow lengths are multiplied by a factor of 3000 for better visualisation. The grey arrows are a subset of the Hosek et al. (2022) proper motions, showing 33% of the stars with more than 80% cluster probability. Black dashed lines denote the approximate outline of our FOV. The dashed purple circle denotes Quintuplet’s core radius r_c, the solid purple circle its tidal radius r_t (adopted from Rui et al. 2019), and the purple arrow pointing at the centre denotes the direction of the orbit of Quintuplet (Fig. 6 in Hosek et al. 2022). Green coloured squares denote spectroscopic hot Quintuplet stars from Clark et al. (2018a), magenta triangles are Paschen α candidates from Dong et al. (2011).
