    A spectroscopic and proper motion search of Sloan Digital Sky Survey: red subdwarfs in binary systems
    Red subdwarfs in binary systems are crucial for both model calibration and spectral classification. We search for red subdwarfs in binary systems from a sample...
  • Publication
    A spectroscopic atlas of post-AGB stars and planetary nebulae selected from the IRAS point source catalogue
    Aims.We study the optical spectral properties of a sample of stars showing far infrared colours similar to those of well-known planetary nebulae. The large...

    A spectroscopic study of the blue stragglers in M67
    Based on spectrophotometric observations from the Guillermo Haro Observatory (Cananea, Mexico), a study of the spectral properties of the complete sample of 24...
  • Publication
    A spectroscopic study of the β Cephei star 12 (DD) Lacertae
    We present first results of a spectroscopic multisite campaign for 12 (DD) Lacertae (hereinafter 12 Lac). This star is one of the best observed β Cephei stars...
  • Publication
    A spectroscopic survey of Abell 1703: is it a rare relaxed cluster hosting a radio halo or a usual merging system?
    We present the study of the internal dynamics of the intriguing galaxy cluster Abell 1703, a system hosting a probable giant radio halo whose dynamical status...
