    Anchoring the distance scale via X-ray/infrared data for Cepheid clusters: SU Cas 
    Gallo, Luigi C.; Turner, David Gerald, 1945-; Majaess, Daniel J.; Lane, D. J.; Gieren, W.; Bonatto, C.; Balam, D.; Berdnikov, L. (American Astronomical SocietyIOP Publishing, 2012-07-10)
    New X-ray (XMM-Newton) and JHK[subscript s] (Observatoire du Mont-Megantic) observations for members of the star cluster Alessi 95, which Turner et al. discovered hosts the classical Cepheid SU Cas, were used in tandem ...

    Investigating potential planetary nebula/cluster pairs 
    Moni Bidin, C.; Majaess, Daniel J.; Bonatto, C.; Mauro, F.; Turner, David Gerald, 1945-; Geisler, D.; Chene, A. -N.; Gormaz-Matamala, A. C.; Borissova, J.; Kurtev, R. G. (EDP Sciences, 2014-01)
    Context. Fundamental parameters characterizing the end-state of intermediate-mass stars may be constrained by discovering planetary nebulae (PNe) in open clusters (OCs). Cluster membership may be exploited to establish the ...

    Massive open star clusters using the VVV survey I. Presentation of the data and description of the approach 
    Majaess, Daniel J.; Chene, A.-N.; Borissova, J.; Clarke, J. R. A.; Bonatto, C.; Bidin, C. Moni; Sale, S. E.; Mauro, F.; Kurtev, R.; Baume, G. (EDP Sciences for European Southern Observatory, 2012-09)
    Context. The ESO Public Survey “VISTA Variables in the Vía Láctea” (VVV) provides deep multi-epoch infrared observations for unprecedented 562 sq. degrees of the Galactic bulge, and adjacent regions of the disk. Aims. The ...

    Massive open star clusters using the VVV survey II. Discovery of six clusters with Wolf-Rayet stars 
    Majaess, Daniel J.; Chene, A.-N.; Borissova, J.; Bonatto, C.; Baume, G.; Clarke, J. R. A.; Kurtev, R.; Schnurr, O.; Bouret, J.-C.; Catelan, M. (EDP Sciences for European Southern Observatory, 2013-01)
    Context. The ESO Public Survey “VISTA Variables in the Vía Láctea” (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge, and adjacent regions of the disk. Nearly ...

    On the crucial cluster Andrews-Lindsay 1 and a 4% distance solution for its planetary nebula 
    Majaess, Daniel J.; Carraro, G.; Moni Bidin, C.; Bonatto, C.; Turner, David Gerald, 1945-; Moyano, M.; Berdnikov, L.; Giorgi, E. (EDP Sciences, 2014-07)
    Andrews-Lindsay 1 is a pertinent open cluster because it may host the planetary nebula (PN) PHR 1315-6555, yet ambiguities linger concerning its fundamental parameters (>50% scatter). New multiband BV JHW1−4 ...

    Strengthening the open cluster distance scale via VVV photometry 
    Majaess, Daniel J.; Turner, David Gerald, 1945-; Bidin, C. Moni; Geisler, D.; Borissova, J.; Minniti, D.; Bonatto, C.; Gieren, W.; Carraro, G.; Kurtev, R. (EDP Sciences, 2012-01)
    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 ...
