A volume-limited survey of mCP stars within 100 pc – I. Fundamental parameters and chemical abundances [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We present the first results of a volume-limited survey of main sequence (MS) magnetic chemically peculiar (mCP) stars. The sample consists of all identified intermediate-mass MS stars (mCP and non-mCP) within a heliocentric distance of $100\,{\rm pc ...

Laser-Induced Breakdown Spectroscopy for Determination of Spectral Fundamental Parameters

open access: yesApplied Sciences, 2020
In this review, we report and critically discuss the application of LIBS for the determination of plasma-emission fundamental parameters, such as transition probabilities, oscillator strengths, Stark broadening and shifts, of the emission lines in the ...

When a Period Is Not a Full Stop: Light Curve Structure Reveals Fundamental Parameters of Cepheid and RR Lyrae Stars [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
The period of pulsation and the structure of the light curve for Cepheid and RR Lyrae variables depend on the fundamental parameters of the star: mass, radius, luminosity, and effective temperature.

Asteroseismic Analysis of δ Scuti Components of Binary Systems: The Case of KIC 8504570

open access: yesGalaxies, 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 ...

Constraints on HD 113337 fundamental parameters and planetary system [PDF]

open access: yesAstronomy & Astrophysics, 2019
Context. HD 113337 is a main-sequence F6V field star more massive than the Sun. This star hosts one confirmed giant planet and possibly a second candidate, detected by radial velocities (RVs).

New Light Curve Analysis for Large Numbers of Eclipsing Binaries I. Detached and Semi-Detached Binaries [PDF]

open access: yesJournal 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 ...

Solar astrophysical fundamental parameters [PDF]

open access: yesSPIE Proceedings, 2014
The accurate determination of the solar photospheric radius has been an important problem in astronomy for many centuries. From the measurements made by the PICARD spacecraft during the transit of Venus in 2012, we obtained a solar radius of 696,156±145 kilometres. This value is consistent with recent measurements carried out atmosphere.

Parameter Identifiability of Fundamental Pharmacodynamic Models [PDF]

open access: yesFrontiers in Physiology, 2016
Issues of parameter identifiability of routinely used pharmacodynamics models are considered in this paper. The structural identifiability of 16 commonly applied pharmacodynamic model structures was analyzed analytically, using the input-output approach.

FUNDAMENTAL PARAMETERS OF MAIN-SEQUENCE STARS IN AN INSTANT WITH MACHINE LEARNING [PDF]

open access: yesarXiv.org, 2016
Owing to the remarkable photometric precision of space observatories like Kepler, stellar and planetary systems beyond our own are now being characterized en masse for the first time.

Fundamental Parameters For Microanalysis [PDF]

open access: yesMicroscopy Today, 1996
Abstract In order to perform quantitative X-ray microanalysis many parameters, representing the various stages of X-ray generation and transport through the specimen at the chosen experimental conditions, must be known for all of the elements that might be encountered.
