Since the release of the Hipparcos catalog in 1997, the distance to the Pleiades open cluster has been heavily debated. The distance obtained from Hipparcos and those by alternative methods differ by 10 to 15 %. As accurate stellar distances are key to understanding stellar structure and evolution, this dilemma puts the validity of stellar evolution models into question. Using our model-independent method to determine parallaxes based on twin stars, we report individual parallaxes of 15 FGK… Expand

A revised moving cluster distance to the Pleiades open cluster
Aims: We provide a new distance estimate for the Pleiades based on the moving cluster method, which will be useful to further discuss the so-called Pleiades distance controversy and compare it withExpand
The Pleiades apex and its kinematical structure
A study of cluster characteristics and internal kinematical structure of the middle-aged Pleiades open star cluster is presented. The individual star apexes and various cluster kinematical parametersExpand
Fundamental Properties of Co-Moving Stars observed by $Gaia$
We have estimated fundamental parameters for a sample of co-moving stars observed by $Gaia$ and identified by Oh et al. (2017). We matched the $Gaia$ observations to the 2MASS and WISE catalogs andExpand
Climbing the cosmic ladder with stellar twins in RAVE with Gaia
We apply the twin method to determine parallaxes to 232 545 stars of the RAVE survey using the parallaxes of Gaia DR1 as a reference. To search for twins in this large data set, we apply theExpand
The RAVE-on catalog of stellar atmospheric parameters and chemical abundances for chemo-dynamic studies in the Gaia era
The orbits, atmospheric parameters, chemical abundances, and ages of individual stars in the Milky Way provide the most comprehensive illustration of galaxy formation available. The Tycho-GaiaExpand
Eclipsing Binary Stars as Benchmarks for Trigonometric Parallaxes in the Gaia Era
We present fits to the broadband photometric spectral energy distributions (SEDs) of 158 eclipsing binaries (EBs) in the Tycho-2 catalog. These EBs were selected because they have highly preciseExpand
Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties
Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7.Expand
With the best data, I find that nearly all 0.5 to 1.2 M main sequence stars converge to a single rotational mass-dependent sequence after 750 Myr; when M > 0.8 M , most of them converge in ≈ 120 Myr.Expand
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

Computing the Parallax of the Pleiades from the Hipparcos Intermediate Astrometry Data: An Alternative Approach
The inconsistency between the mean parallax of the Pleidaes open cluster from the Hipparcos catalog and that obtained from the stellar evolution theory and photometric measurements is probed byExpand
The problem of the Pleiades distance - Constraints from Strömgren photometry of nearby field stars
The discrepancy between the Pleiades cluster distance based on Hipparcos parallaxes and main sequence tting is investigated on the basis of Stromgren photometry of F-type stars. Field stars with theExpand
A distance of 133–137 parsecs to the Pleiades star cluster
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
Climbing the cosmic ladder with stellar twins
Distances to stars are key to revealing a three-dimensional view of the Milky Way, yet their determination is a major challenge in astronomy. Whilst the brightest nearby stars benefit from directExpand
A VLBI resolution of the Pleiades distance controversy
An absolute trigonometric parallax distance measurement to the Pleiades cluster that uses very long baseline radio interferometry (VLBI) is presented, which is the most accurate and precise yet presented for the cluster and is incompatible with the Hipparcos distance determination. Expand
The distance to the Pleiades: Main sequence fitting in the near infrared
Hipparcos parallax measurements of stars in the Pleiades notoriously result in a cluster distance of 118 pc, which is approximately 10% shorter than the "classical" result obtained from earlier mainExpand
