Hertzsprung-Russell diagram of the Hyades. The red and blue sources indicate Hyades members in the core and in the tails, respectively. The orange sources are only associated to the Hyades by Lodieu et al. (2019), sources outlined in black are detected X-rays. The theoretical main sequence adopted from Worthey & Lee (2011) is shown by the black solid line, while the dashed lines indicate the values 2.5 mag brighter and fainter than the main sequence.
