Photospheric properties and fundamental parameters of M dwarfs [PDF]
A&A 610, A19 (2018), 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. Being the most numerous and oldest stars in the galaxy, they carry fundamental information on its chemical history.

Accurate Fundamental Stellar Parameters [PDF]
Proceedings 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 ...

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

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.

Precision $Υ$ Spectroscopy and Fundamental Parameters From NRQCD [PDF]
Nucl.Phys.Proc.Suppl.34:417-424,1994, 1993 We present results from a high precision NRQCD simulation of the quenched $\Upsilon$ system at $\beta = 6$. We demonstrate a variety of important lattice techniques, including the perturbative improvement of actions, tadpole improvement, and multicorrelated fits for extracting the spectrum of excited states.

Fundamental parameters of QCD [PDF]
, 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 Parameters and Chemical Composition of Arcturus [PDF]
The 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.

Concluding Remarks on New Cosmological Data and the Values of the Fundamental Parameters [PDF]
arXiv, 2000 I review the reason for considering the prime purpose of the program of measurements of the fundamental parameters of cosmology to be the tests of cosmological models. I comment on the philosophy by which we are approaching this goal, offer an assessment of where we stand, and present some thoughts on where the tests may be headed.

Fundamental Parameters of Cepheids: Masses and Multiplicity [PDF]
AIP Conference Proceedings, 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.
