Fundamental parameters - Open Access .click

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.
