A VLBI resolution of the Pleiades distance controversy.
Because of its proximity and its youth, the Pleiades open cluster of stars has been extensively studied and serves as a cornerstone for our understanding of the physical properties of young stars. This role is called into question by the "Pleiades distance controversy," wherein the cluster distance of 120.2 ± 1.5 parsecs (pc) as measured by the optical space astrometry mission Hipparcos is sign...
متن کاملToward a resolution of the Rorschach controversy.

متن کاملThe Distance of the Pleiades and Nearby Clusters
We have determined the distance to nearby open clusters from the means of Hipparcos parallaxes re-computed from the intermediate data. The rst result worth noticing is that Praesepe, Coma Ber, Persei and Blanco 1 deene the same main sequence in spite of their diierences in metallicity. The second and more surprising result is that the Pleiades, and probably IC 2391 and 2602, deene a sequence ab...
