ContextIn the absence of complete kinematic data it has not previously been possible to furnish accurate lists of member stars for all moving groups. There has been an unresolved dispute concerning the apparent inconsistency of the Hipparcos parallax distance to the Pleiades.AimsTo find improved candidate lists for clusters and associations represented among Hipparcos stars, to establish distances, and to cast light on the Pleiades distance anomaly.MethodsWe use a six dimensional fitting… Expand

Investigation of Galactic open cluster remnants: the case of NGC 7193
• Physics
• 2016
Galactic open clusters (OCs) that survive the early gas-expulsion phase are gradually destroyed over time by the action of disruptive dynamical processes. Their final evolutionary stages areExpand
Orbits, Distance, and Stellar Masses of the Massive Triple Star Sigma Orionis
We present interferometric observations of the sigma Orionis triple system using the CHARA Array, NPOI, and VLTI. Using these measurements, we spatially resolve the orbit of the close spectroscopicExpand
Two estimates of the distance to the Galactic Centre
• Physics
• 2014
We use recently updated globular cluster distances to estimate the distance to the Galactic centre, finding 7.4 \pm 0.2|stat \pm 0.2|sys kpc from symmetry considerations. We recalibrate the red clumpExpand
An application of the KNND method for detecting nearby open clusters based on Gaia-DR1
This paper presents a preliminary test of the k-th nearest neighbor distance (KNND) method for detecting nearby open clusters based on Gaia-DR1. We select 38 386 nearby stars (< 100 pc) from theExpand
The local standard of rest and the well in the velocity distribution
• Physics
• 2014
It is now recognised that the traditional method of calculating the LSR fails. We find an improved estimate of the LSR by making use of the larger and more accurate database provided by XHIP andExpand

A distance of 133–137 parsecs to the Pleiades star cluster
• Physics, Medicine
• Nature
• 2004
The orbital parameters of the bright double star Atlas in the Pleiades are reported, using long-baseline optical/infrared interferometry, to derive a firm lower bound of D > 127’pc, with the most likely range being 133 < D < 137 pc. Expand
