    • Low-resolution near-infrared spectroscopic signatures of unresolved ultracool companions to M dwarfs 

      Cook, Neil; Pinfield, D. J.; Marocco, F.; Burningham, B.; Jones, H. R. A.; Frith, J.; Zhong, J.; Luo, A. L.; Qi, Z. X.; Cowan, N. B.; Gromadzki, M.; Kurtev, R.G.; Guo, Y. X.; Wang, Y. F.; Song, Y. H.; Yi, Z. P.; Smart, R. L. (2017-06-01)
      We develop a method to identify the spectroscopic signature of unresolved L-dwarf ultracool companions, which compares the spectra of candidates and their associated control stars using spectral ratio differences and ...

    • 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. ...
