Lessons from the curious case of the ‘fastest’ star in Gaia DR2

Lessons from the curious case of the ‘fastest’ star in Gaia DR2

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 differenc...
