Fundamental parameters of B type stars [PDF]

Proceedings of the International Astronomical Union, 2014
AbstractFundamental parameters of 26 well-studied sharp-lined single early B-type stars in OB associations and in the field within a distance of ≤400 pc from the Sun are compared to high-precision data from detached eclipsing binaries (DEBs). Fundamental parameters are derived from accurate and precise atmospheric parameters determined earlier by us ...

CHEMICAL COMPOSITION OF 4 STARS IN THE HYADES

Odessa Astronomical Publications, 2017
The parameters of atmospheres (Теf, 1оg g, [fе/Н], Vt) of 4 stars of Hyades are certain. Spectrums are got on a spectrograph ELODIE on a 1.93m telescope in the observatory of OHP (France). Overabundances  are got 0.1 dех for all investigated elements.

The Solar Twin Planet Search. I. Fundamental parameters of the stellar sample [PDF]

, 2014
Context. We are carrying out a search for planets around a sample of solar twin stars using the HARPS spectrograph. The goal of this project is to exploit the advantage offered by solar twins to obtain chemical abundances of unmatched precision.

Fundamental parameters of Be stars located in the seismology fields of COROT [PDF]

, 2005
In preparation for the COROT space mission, we determined the fundamental parameters (spectral type, temperature, gravity, vsini) of the Be stars observable by COROT in its seismology fields (64 Be stars).

Setting Up of the Strömvil System Standards and Standard Regions

Open Astronomy, 2003
CCD photometry of standard areas of the seven-color Strömvil photometric system in some open and globular clusters is described. The primary standards are being measured with a two-channel photoelectric photometer on the 1.5 meter telescope on Mt. Lemmon.

The First Comprehensive Photometric Study of the Neglected Binary System V345 Cassiopeiae [PDF]

Journal of Astronomy and Space Sciences, 2013
We present the first BVRI CCD photometric observations of V345 Cas made on 22 nights during the observing seasons in 2007-2008. Our light curves, resembling those of EB-type binary stars, are analyzed with the 2003 version of the Wilson- Devinney ...
