    Spectroscopic and Photometric Analysis of the HW Vir Star PTF1 J011339.09+225739.1
    HW Vir systems are rare eclipsing binary systems including a subdwarf B star (sdB) with a faint companion, mostly M-dwarfs. Up to now, 19 HW Vir systems have...

    Spectroscopic and photometric evidence of two stellar populations in the Galactic globular cluster NGC 6121 (M 4)
    Aims: We present abundance analysis based on high resolution spectra of 105 isolated red giant branch (RGB) stars in the Galactic Globular Cluster NGC 6121 (M 4...
  • Publication
    Spectroscopic and photometric periods of six ultracompact accreting binaries
    Ultracompact accreting binary systems each consist of a stellar remnant accreting helium-enriched material from a compact donor star. Such binaries include two...

    Spectroscopic and physical parameters of Galactic O-type stars. I. Effects of rotation and spectral resolving power in the spectral classification of dwarfs and giants
    Context. The modern-era spectral classification of O-stars relies on either the Walborn or the Conti-Mathys scheme. Since both of these approaches have been...
  • Publication
    Spectroscopic and physical parameters of Galactic O-type stars. II. Observational constraints on projected rotational and extra broadening velocities as a function of fundamental parameters and stellar evolution
    Context. Rotation is of key importance for the evolution of massive star, including their fate as supernovae or gamma-ray bursts. However, the rotational...

    Spectroscopic and seismic analysis of red giants in eclipsing binaries discovered by Kepler
    Eclipsing binaries (EBs) are unique targets for measuring accurate stellar properties and constraining stellar evolution models. In particular, it is possible...

    Spectroscopic Atlas of the Central 24^''x20^'' of the Seyfert 2 Galaxy NGC 1068
    Two-dimensional spectroscopy of the central 24^''x20^'' of the Seyfert 2 galaxy NGC 1068 has been obtained using a fiber-optic system (2D-FIS). The homogeneity...
  • Publication
    Spectroscopic characterization of a sample of metal-poor solar-type stars from the HARPS planet search program. Precise spectroscopic parameters and mass estimation
    Stellar metallicity strongly correlates with the presence of planets and their properties. To check for new correlations between stars and the existence of an...

    Spectroscopic characterization of the known O-star population in Cygnus OB2. Evidence of multiple star-forming bursts
    Context. Cygnus OB2 provides a unique insight into the high-mass stellar content in one of the largest groups of young massive stars in our Galaxy. Although...
