Fundamental parameters of BE UMa revised

Astronomy Reports, 2008
We have determined a complete set of parameters for the young pre-cataclysmic variable BE UMa from a comprehensive photometric and spectroscopic analysis using model atmospheres. Our precise photometry and spectroscopy were acquired with the 6-m telescope and Zeiss-1000 telescope of the Special Astrophysical Observatory and the 1.5-m Russian-Turkish ...

Fundamental Parameters of Antennas

2009
The most basic properties of an antenna are its radiation pattern, gain, impedance, and polarization. These properties are identical for linear passive antennas used either as a transmitter or receiver by virtue of the reciprocity theorem [1]. A complete definition of the terms used for antennas can be found in [2]. The radiation pattern is defined in

The Fundamental Parameters of Cosmology

Publications of the Astronomical Society of the Pacific, 1999
I describe the evidence for the big bang, including the various cosmological parameters. There is general concordance on their values, although the uncertainties remain large enough to justify the ensuing debate. Structure formation is reviewed, and here there is consensus on the hierarchical nature of the sequence of formation.

The Fundamental Parameters of Massive Stars

AIP Conference Proceedings, 2009
We analyzed far‐UV (FUSE), UV (HST, IUE) and optical spectra of hot massive stars in the Milky Way with non‐LTE, line‐blanketed models with sphericity and expanding winds. We were able to reconcile previously discrepant diagnostics from Hα to highly ionized transitions (e.g.

Analysis of fundamental parameters for V477 Lyr

Astronomy Letters, 2008
We analyze the photometric and spectroscopic observations of the young pre-cataclysmic variable (pre-CV) V477 Lyr. The masses of both binary components have been corrected by analyzing their radial velocity curves. We show that agreement between the theoretical and observed light curves of the object is possible for several sets of its physical ...
