Carbon-enhanced metal-poor stars
We revisit the observed frequencies of carbon-enhanced metal-poor (CEMP) stars as a function of the metallicity in the Galaxy, using data from the literature with available... -
Limb-darkening coefficients for eclipsing WD*
We present extensive calculations of linear and nonlinear limb-darkening coefficients as well as complete intensity profiles appropriate for modeling the light-curves of... -
Synthetic spectra of dark stars
The first stars in the history of the Universe are likely to form in the dense central regions of {sim.to}10^5^-10^6^ M_{sun} cold dark matter halos at z{approx}10--50. The... -
X-ray spectra of bursting neutron stars
X-ray burst sources represent a class of accreting neutron stars in close binary systems which do not exhibit any traces of the magnetic field. We present new method of hot... -
Calibration of synthetic photometry
We present a new calibration of optical (UBV, Stroemgren uvby{beta}, and Geneva) and near-IR (Johnson RIJHK and Two Micron All Sky Survey) photometry for B and early A stars... -
Improved properties for cool stars
We present new grids of colors and bolometric corrections for F-K stars having 4000 K {<=} Teff {<=} 6500 K, 0.0 {<=} log(g) {<=} 4.5, and -3.0 {<=} [Fe/H]... -
Color-temperature relations of M giants
As part of a project to model the integrated spectra and colors of elliptical galaxies through evolutionary synthesis, we have refined our synthetic spectrum calculations of M... -
Chromospheric emission in late-type stars.
More than 800 southern stars within 50pc have been observed for chromospheric emission in the cores of the Ca II H and K lines. Most of the sample targets were selected to be G... -
Limb-darkening coefficients in binaries
We present monochromatic, passband-specific, and bolometric limb-darkening coefficients for a linear as well as nonlinear logarithmic and square root limb-darkening laws. These... -
CO and HCN observations of circumstellar envelopes
We have searched the literature for all observations of the ^12^CO(1-0), ^12^CO(2-1), and HCN(1-0) lines in circumstellar envelopes of late type stars published between January... -
B to G stars calibration in Geneva photometry
We have used recent Kurucz models and many standard stars to revise previous calibrations of the Geneva photometric parameters in terms of Teff, logg, and [M/H]. In addition,... -
Limb-darkening coefficients for R I J H K
We have computed limb-darkening coefficients for five commonly used near infrared photometric bands, namely R, I, J, H, and K, using the stellar atmosphere models by Kurucz... -
LTE model atmospheres coeff.
Linear, quadratic and square root limb-darkening coefficients have been computed by means of least squares fits to model atmospheres by Kurucz (1991) with the main purpose of... -
Heterochromatic Atmospheric Extinction
In synthetic versions of two broadband photometric systems, Johnson-Cousins and Washington, we find the dependence of atmospheric extinction corrections on colour and on macro... -

M dwarfs model photospheres. II.
We present a table of new "classical" model photospheres for M dwarfs computed with an extensive set of atomic and molecular opacities treated with the accurate and realistic... -

Limb-darkening coefficients for JWST
Modeling observations of transiting exoplanets or close binary systems by comparing the observations with theoretical light curves requires precise knowledge of the distribution... -
Entropy-calibrated stellar modeling
Modeling the convection process is a long-standing problem in stellar physics. To date, all ad hoc models have relied on a free parameter, alpha, (among others) that has no real... -
Power-2 limb-darkening coefficients
The phenomenon of limb-darkening is relevant to many topics in astrophysics, including the analysis of light curves of eclipsing binaries, optical interferometry, measurement of...
