Fundamental Parameters of Massive Stars [PDF]
EAS Publications Series, 2003 We discuss the determination of fundamental parameters of `normal' hot, massive OB-type stars, namely temperatures, luminosities, masses, gravities and surface abundances.

Reconstruction of Fundamental SUSY Parameters [PDF]
Nuclear Physics B - Proceedings Supplements, 2002 We summarize methods and expected accuracies in determining the basic low-energy SUSY parameters from experiments at future e$^+$e$^-$ linear colliders in the TeV energy range, combined with results from LHC. In a second step we demonstrate how, based on

Asteroseismic Analysis of δ Scuti Components of Binary Systems: The Case of KIC 8504570
Galaxies, 2020 The present work concerns the Asteroseismology of the Kepler-detached eclipsing binary KIC 8504570. Particularly, it focuses on the pulsational behaviour of the oscillating component of this system and the estimation of its physical parameters in order ...

New Light Curve Analysis for Large Numbers of Eclipsing Binaries I. Detached and Semi-Detached Binaries [PDF]
Journal of Astronomy and Space Sciences, 2010 Several survey observations have produced light curves of more than five thousand eclipsing binaries for last 15 years. Future missions such as the Large Synoptic Survey Telescope (LSST), the Panoramic Survey Telescope and Rapid Response System (Pan ...

Fundamental Parameters of Cepheids: Masses and Multiplicity [PDF]
, 2009 Masses determined from classical Cepheids in binary systems are a primary test of both pulsation and evolutionary calculations. The first step is to determine the orbit from ground-based radial velocities.

Analysis of Interstellar Extinction towards the Hypergiant Cyg OB2 No. 12
Open Astronomy, 2016 The Cyg OB2 stellar association hosts an entire zoo of unique objects, and among them – an enigmatic star Cyg OB2 No. 12 (Schulte 12, MT 304). MT 304 is enigmatic not only due to its highest luminosity (according to various estimates, it is one of the ...

Wide Field Multicolor CCD Photometry in the Vicinity of the Open Cluster King 7
Open Astronomy, 2010 We present the results of CCD photometry in the seven-color Vilnius system for 1549 stars down to V ∼16 mag in a 1.5 square degree field around the cluster King 7, at the Perseus and Camelopardalis border.

Studying the UV Mg II Resonance Lines in 20 Be Stars
Open Astronomy, 2011 Using the GR model, we analyze the UV Mg II resonance lines in the spectra of 20 Be stars of different spectral subtypes, in order to detect the presence of satellite or discrete absorption components. The values of some physical parameters – rotational,
