A 2018 Gaia DR1 study of the Hyades Cluster determined a (U, V, W) group velocity of (−41.92 ± 0.16, −19.35 ± 0.13, −1.11 ± 0.11) km/sec, based on the space velocities of the 138 core stars. <ref>{{Cite journal |last1=Reino |first1=Stella |last2=de Bruijne |first2=Jos |last3=Zari |first3=Eleonora |last4=d'Antona |first4=Francesca |last5=Ventura |first5=Paolo |date=2018-03-28 |title=A Gaia study of the Hyades open cluster |journal=Monthly Notices of the Royal Astronomical Society |volume=477 |issue=3 |pages=3197–3216 |doi=10.1093/mnras/sty793 |doi-access=free |issn=0035-8711|arxiv=1804.00759 }}</ref>

A 2019 Gaia DR2 study finds a (U, V, W) group velocity of (−42.24, −19.00, −1.48) km/sec, in very close agreement with the 2018 DR1 derivation. <ref>{{Cite journal |last1=Röser |first1=Siegfried |last2=Schilbach |first2=Elena |last3=Goldman |first3=Bertrand |date=2019-01-01 |title=Hyades tidal tails revealed by Gaia DR2 |url=https://www.aanda.org/articles/aa/abs/2019/01/aa34608-18/aa34608-18.html |journal=Astronomy & Astrophysics |language=en |volume=621 |pages=L2 |doi=10.1051/0004-6361/201834608 |arxiv=1811.03845 |bibcode=2019A&A...621L...2R |s2cid=118909033 |issn=0004-6361}}</ref>

Another DR2 study from 2019 focused on mapping the 3D Topology & Velocities of the Hyades main body out to 30 parsecs, and included Sub-Stellar members as well. They identified 1764 member candidates, including 10 Brown Dwarfs and 17 White Dwarfs. The White Dwarfs included 9 single stars, and 4 binary systems. <ref>{{Cite journal |last1=Lodieu |first1=N. |last2=Smart |first2=R.

A 2022 Hyades study utilizing Gaia EDR3 derived a (U, V, W) group velocity of (-42.11±6.50, - 19.09±4.37, -1.32±0.44) km/sec, also with close agreement to DR1 and DR2 studies.<ref>{{Cite journal |last1=Elsanhoury |first1=Waleed |last2=Al-Johani |first2=Amnah |last3=Al-anzi |first3=Aneefah |last4=Al-jaber |first4=Bashayr |last5=Al-Bishi |first5=Fatmah |last6=Kanaan |first6=Nourah |last7=Al-atwi |first7=Ragwa |last8=Al-khubrani |first8=Reem |last9=Al-anzi |first9=Sarah |date=2022-03-16 |title=The Hyades Kinematical Structure with Gaia Era |url=http://op.niscpr.res.in/index.php/IJPAP/article/view/58781 |journal=Indian Journal of Pure & Applied Physics |language=en |volume=60 |issue=3 |pages=268–273 |doi=10.56042/ijpap.v60i3.58781 |s2cid=251335023 |issn=0975-1041|doi-access=free }}</ref>
