    Spectroscopic and Asteroseismic Analysis of the Secondary Clump Red Giant HD 226808
    In order to clarify the properties of the secondary clump star HD 226808 (KIC 5307747), we combined four years of data from Kepler space photometry with high...

    Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
    Context. The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area have focused on highly active objects, those with small...

    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...

    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...
  • Publication
    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...
  • Publication
    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...
