Fundamental Parameters of Massive Stars [PDF]

open access: yesEAS 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]

open access: yesNuclear 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

An Implementation of the Fundamental Parameters Approach for Analysis of X-ray Powder Diffraction Line Profiles. [PDF]

open access: yesJ Res Natl Inst Stand Technol, 2015
This work presents an open implementation of the Fundamental Parameters Approach (FPA) models for analysis of X-ray powder diffraction line profiles. The original literature describing these models was examined and code was developed to allow for their ...

Fundamental Parameters and Chemical Composition of Arcturus [PDF]

open access: yesThe Astrophysical Journal, 2011
We derive a self-consistent set of atmospheric parameters and abundances of 17 elements for the red giant star Arcturus: Teff = 4286+/-30 K, logg = 1.66+/-0.05, and [Fe/H] = -0.52+/-0.04.

New Limits on Fundamental Weak-Interaction Parameters from SuperallowedβDecay [PDF]

open access: green, 2005
A new critical survey of all world data on superallowed beta decays provides demanding tests of, and tight constraints on, the weak interaction. In confirmation of the conserved vector current (CVC) hypothesis, the vector coupling coupling constant is ...

Fundamental parameters of QCD [PDF]

open access: yes, 2002
The theory of strong interactions, QCD, is described in terms of a few parameters, namely the strong coupling constant alpha_s and the quark masses. We show how these parameters can be determined reliably using computer simulations of QCD on a space-time

Fundamental stellar parameters [PDF]

open access: green, 2004
I present a discussion of fundamental stellar parameters and their observational determination in the context of interferometric measurements with current and future optical/infrared interferometric facilities. Stellar parameters and the importance of their determination for stellar physics are discussed.

Accurate Fundamental Stellar Parameters [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
We combine results from interferometry, asteroseismology and spectroscopic analyses to determine accurate fundamental parameters (mass, radius and effective temperature) of 10 bright solar-type stars covering the H-R diagram from spectral type F5 to K1 ...

Photospheric properties and fundamental parameters of M dwarfs [PDF]

open access: yes, 2017
M dwarfs are an important source of information when studying and probing the lower end of the Hertzsprung-Russell (HR) diagram, down to the hydrogen-burning limit.
