Lessons from the curious case of the ‘fastest’ star in Gaia DR2
- Abstract:
-
Gaia DR2 5932173855446728064 was recently proposed to be unbound from the Milky Way based on the −614.3 ± 2.5 km s−1 median radial velocity given in Gaia DR2. We obtained eight epochs of spectroscopic follow-up and find a very different median radial velocity of −56.5 ± 5.3 km s−1. If this difference were to be explained by binarity, then the unseen companion would be an intermediate-mass black hole; we therefore argue that the Gaia DR2 radial velocity must be in error. We find it likely that...
