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 ...

Cross Catalogue Matching with Virtual Observatory and Parameterization of Stars
Open Astronomy, 2012 Virtual Observatory facilities allow users to make a fast and correct cross-matching of objects from various surveys. They yield multi-color photometry data (color indices) on registered objects and make it possible to determine stellar parameters.

On the Nature of the Core of α Centauri A: The Impact of the Metallicity Mixture
Frontiers in Astronomy and Space Sciences, 2019 Forward asteroseismic modeling plays an important role toward a complete understanding of the physics taking place in deep stellar interiors. With a dynamical mass in the range over which models develop convective cores while in the main sequence, the ...

Spectral Classification of Faint Carbon Stars
Open Astronomy, 2003 R-N classification of 187 faint carbon stars is based on the classical criteria adjusted to the yellow-red spectral region, with two new criteria added - the ratios of the red CN bands 6206/6332 (Å) and 6478/6631 (Å).

Accurate fundamental parameters for Lower Main Sequence Stars
, 2006 We derive an empirical effective temperature and bolometric luminosity calibration for G and K dwarfs, by applying our own implementation of the InfraRed Flux Method to multi-band photometry.

Nonlinear estimation of the fundamental matrix with minimal parameters [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2004 The purpose of this paper is to give a very simple method for nonlinearly estimating the fundamental matrix using the minimum number of seven parameters. Instead of minimally parameterizing it, we rather update what we call its orthonormal representation, which is based on its singular value decomposition.

Open Astronomy, 2003 We present a new color index vs. absolute magnitude calibration of 2MASS JHK photometry. For the A0 to ~G5 and M segments of the main sequence information on the amount of interstellar extinction and its location in space may be obtained.
