WR 35a: A new double-lined spectroscopic binary
(EDP Sciences, 2014-02)
Aims. We present the first orbital solution for the Wolf-Rayet star, WR 35a, that was discovered by a spectroscopic monitoring of faint WN-type stars.
Methods. Spectral features of two different components were identified, ...
Spectroscopic metallicities of Vega-like stars
(EDP Sciences, 2008-10)
Aims. We aim to determine the metallicities of 113 Southern Hemisphere Vega-like candidate stars in relation to the giant exoplanet host group and field stars. Methods. We applied two spectroscopic methods of abundance ...
Spectroscopic and photometric analysis of the early-type spectroscopic binary HD 161853 in the centre of an H ii region (Research Note)
(Edp Sciences, 2015-12)
Aims. We study the O-type star HD 161853, which has been noted as a probable double-lined spectroscopic binary system.
Methods. We secured high-resolution spectra of HD 161853 during the past nine years. We separated the ...
Enhanced bulk and superficial hydrophobicities of starch-based bionanocomposites by addition of clay
(2013-10-01)
In this work, thermoplastic starch (TPS)-clay bionanocomposites were obtained by an innovative methodology using a combination of methodologies commonly used in the composites and nanocomposites preparations. The main ...

Spectroscopic study of early-type multiple stellar systems II. New binary subsystems.
(EDP Sciences, 2014-07)
Context. This work is part of a long-term spectroscopic study of a sample of 30 multiple stars with early-type components. In this second paper we present the results for six multiple systems in which new stellar components ...
Orbits for eighteen visual binaries and two double-line spectroscopic binaries observed with hrcam on the CTIO SOAR 4m telescope, using a new bayesian orbit code based on markov chain Monte Carlo
(IOP Publishing Ltd., 2017)
We present orbital elements and mass sums for 18 visual binary stars of spectral types B to K (five of which are new orbits) with periods ranging from 20 to more than 500 yr. For two double-line spectroscopic binaries with ...
Spectroscopic parameters and atmospheric chemistries of stars (SPECIES) I. Code description and dwarf stars catalogue
(Edp Sciences, 2018-07-17)
Context. The detection and subsequent characterisation of exoplanets are intimately linked to the characteristics of their host star. Therefore, it is necessary to study the star in detail in order to understand the formation ...
