      We describe two ground based observing campaigns aimed at building a grid of approximately 200 spectrophotometric standard stars (SPSS), with an internal ~1% precision and tied to Vega within ~3%, for the absolute flux ...

      Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical ...

    • The young open cluster NGC 7067 using Stromgren photometry 

      Monguio, Maria; Negueruela, I.; Marco, A.; González-Fernández, C.; Alonso-Santiago, Javier; Costado, M. T.; Casamiquela, Laia; Lopez-Corredoira, M.; Molgo, J.; Vilardell, F.; Alfaro, E.; Antoja, T.; Figueras, Francesca; Garcia, Miriam; Jordi, C.; Romero-gomez, M. (2017-04-01)
      NGC 7067 is a young open cluster located in the direction between the first and the second Galactic quadrants and close to the Perseus spiral arm. This makes it useful for studies of the nature of the Milky Way spiral arms. ...
