    • The deep OB-star population in Carina from the VST Photometric H-alpha Survey (VPHAS+) 

      Mohr-Smith, M.; Drew, Janet; Napiwotzki, Ralf; Simon-Diaz, S.; Wright, N. J.; Barentsen, Geert; Eisloeffel, J.; Farnhill, Hywel; Greimel, R.; Monguio, Maria; Kalari, V.; Parker, Q. A.; Vink, Jorick S. (2017-02-21)
      Massive OB stars are critical to the ecology of galaxies and yet our knowledge of OB stars in the Milky Way, fainter than V ∼ 12, remains patchy. Data from the VST Photometric Hα Survey (VPHAS+) permit the construction of ...

    • The Gaia-ESO Survey: pre-main-sequence stars in the young open cluster NGC 3293 

      Delgado, A. J.; Sampedro, L.; Alfaro, E. J.; Costado, M. T.; Yun, J. L.; Frasca, A.; Lanzafame, A. C.; Drew, J. E.; Eislöffel, J.; Blomme, R.; Morel, T.; Lobel, A.; Semaan, T.; Randich, S.; Jeffries, R. D.; Micela, G.; Vallenari, A.; Kalari, V.; Gilmore, G.; Flaccomio, E.; Carraro, G.; Lardo, C.; Monaco, L.; Prisinzano, L.; Sousa, S. G.; Morbidelli, L.; Lewis, J.; Koposov, S.; Hourihane, A.; Worley, C.; Casey, A.; Franciosini, E.; Sacco, G.; Magrini, L. (2016-08-11)
      The young open cluster NGC3293 is included in the observing program of the Gaia-ESO survey (GES). The radial velocity values provided have been used to assign cluster membership probabilities by means of a single-variable ...

    • New OB star candidates in the Carina Arm around Westerlund 2 from VPHAS+ 

      Mohr-Smith, M.; Drew, J.E.; Barentsen, G.; Wright, N. J.; Napiwotzki, R.; Corradi, R.L.M.; Eislöffel, J.; Groot, P.; Kalari, V.; Parker, Q. A.; Raddi, Roberto; Sale, S. E.; Unruh, Y.C.; Vink, J. S.; Wesson, R. (2015-07-11)
      O and early B stars are at the apex of galactic ecology, but in the Milky Way, only a minority of them may yet have been identified. We present the results of a pilot study to select and parametrise OB star candidates in ...
