    • New evidence supporting membership for TW nor in Lyngå 6 and the centaurus spiral arm 

      Majaess, D.; Turner, D.; Moni Bidin, C.; Mauro, F.; Geisler, D.; Gieren, W.; Chené, A.-N.; Minniti, D.; Saito, R.K.; Minniti, D.; Minniti, D.; Chené, A.-N.; Borissova, J.; Kurtev, R.; Lucas, P.W.; Dékny, I. (2011)
      The putative association between the 10. 8 classical Cepheid TW Nor and the open cluster Lyngå 6 has generated considerable debate in the literature.NewJHK photometry in tandem with existing radial velocities for Lyngå 6 ...

      The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is an ongoing time-series, near-infrared (IR) survey of the Galactic bulge and an adjacent portion of the inner disk, covering 562 square degrees of the sky, ...

    • Strengthening the open cluster distance scale via VVV photometry 

      Majaess, D.; Turner, D.; Moni Bidin, C.; Geisler, D.; Borissova, J.; Minniti, D.; Bonatto, C.; Gieren, W.; Carraro, G.; Kurtev, R.; Mauro, F.; Chené, A.-N.; Forbes, D.; Lucas, P.W.; Dékány, I.; Saito, R.K.; Soto, M. (2012)
      Approximately 14% of known Galactic open clusters possess absolute errors ≤20% as evaluated from n ≥ 3 independent distance estimates, and the statistics for age estimates are markedly worse. That impedes such diverse ...

    • Three galactic globular cluster candidates 

      Moni Bidin, C.; Mauro, F.; Geisler, D.; Chené, A.-N.; Minniti, D.; Catelan, M.; Hempel, M.; Valcarce, A.A.R.; Alonso-García, J.; Zoccali, M.; Valenti, E.; Carraro, G.; Valcarce, A.A.R.; Borissova, J.; Chené, A.-N.; Kurtev, R.G.; Lucas, P.W. (2011-10-27)
      Context. The census of Galactic globular clusters (GCs) is still incomplete, and about ten new objects are supposed to await discovery, hidden behind the crowded and reddened regions of the Galactic bulge and disk. Aims. ...
