  • GALPROP programme

    We exploit synchrotron radiation to constrain the low-energy interstellar electron spectrum, using various radio surveys and connecting with electron data from Fermi-LAT and...
  • Visibilities of stellar oscillation modes

    Kepler produces a large amount of data used for asteroseismological analyses, particularly of solar-like stars and red giants. The mode amplitudes observed in the Kepler...
  • Grid of Lya radiation transfer models

    Ly{alpha} is a key diagnostic for numerous observations of distant star-forming galaxies, but detailed radiation transfer models are required for interpreting them. We provide...
  • Limb-darkening coefficients

    The degree of complexity of physics due to proximity effects in close binary stars is one of the most important challenges in theoretical stellar physics. The knowledge of how...
  • X-ray bursting neutron star atmosphere models

    X-ray bursting neutron stars in low mass X-ray binaries constitute an appropriate source class to constrain masses and radii of neutron stars, but a sufficiently extended set of...
  • Algorithm for correcting CoRoT raw light curves

    We introduce the CoRoT Detrend Algorithm (CDA) for detrending CoRoT stellar light curves. CDA has the capability to remove random jumps and systematic trends encountered in...
  • Sensitivity analysis list of chemical reactions

    Because of new telescopes that will dramatically improve our knowledge of the interstellar medium, chemical models will have to be used to simulate the chemistry of many regions...
  • Reduction of integral-field spectrograph code P3D

    The reduction of integral-field spectrograph (IFS) data is demanding work. Many repetitive operations are required to convert raw data into, typically, a large number of...
  • Teff and Fbol from Infrared Flux Method

    Various effective temperature scales have been proposed over the years. Despite much work and the high internal precision usually achieved, systematic differences of order 100K...
  • Grid of solar-metallicity wind models

    Knowing how the mass loss of carbon-rich AGB stars depends on stellar parameters is crucial for stellar evolution modelling, as well as for the understanding of when and how...
  • Magnetic fields in white dwarfs

    A large number of magnetic white dwarfs discovered in the SDSS have so far only been analyzed by visual comparison of the observations with relatively simple models of the...
  • Dust coagulation in molecular clouds

    The cores in molecular clouds are the densest and coldest regions of the interstellar medium (ISM). In these regions ISM-dust grains have the potential to coagulate. This study...
  • Physical parameters from JHK flux

    The effective temperature scale of FGK stars, especially at the lowest metallicities remains a major problem in the chemical abundance analysis of metal-poor stars. We present a...
  • Barnes-Evans relations for dwarfs

    Barnes-Evans type relations provide an empirical relationship between the surface brightness of stars and their color. They are widely used for measuring the distances to stars...
  • UBVJHK synthetic photometry of Galactic O stars

    The development of powerful infrared observational techniques enables the study of very extincted objects and young embedded star-forming regions. This is especially interesting...
  • Modelling the Galactic Interstellar Extinction

    The Two Micron All Sky Survey (Cat. ), along with the Stellar Population Synthesis Model of the Galaxy, developed in Besancon, is used to calculate the extinction distribution...
  • Late-type giants BVRIJHKL and Teff calibration

    We present new synthetic broad-band photometric colors for late-type giants based on synthetic spectra calculated with the PHOENIX model atmosphere code. The grid covers...
  • Fundamental parameters of fast-rotating B stars

    In this paper we develop a calculation code to account for the effects carried by fast rotation on the observed spectra of early-type stars. Stars are assumed to be in rigid...
  • Non-linear limb-darkening law for LTE models. III.

    Continuing our studies on stellar atmospheres (Claret, 2000, Cat. , 2003, Cat. ), we present in this paper the limb-darkening coefficients for the Sloan photometric system. The...
  • Relativistic corrections to Sunyaev-Zeldovich effect

    These tables contain numerical values for the distortion of the spectral intensity {Delta}I/y defined by the equation {Delta}I/y = 1/y * X^3^/(e^X^-1) * {Delta}n(X)/n0(X) =...
