    Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observations
    Context. The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE...

    Constraints on the cosmic equation of state: Age conflict versus phantom energy. Age-redshift relations in an accelerated universe
    The currently available values and confidence limits for Ωm0, H0 and globular cluster ages still indicate that the dark energy that dominates the Universe could...

    Constraints on the exosphere of CoRoT-7b
    Context. The small radius and high density of CoRoT-7b implies that this transiting planet belongs to a different species than all transiting planets previously...

    Constraints on the use of Be I lines for deriving beryllium abundances in late-type dwarf stars.
    Beryllium is a key element for constraining mixing processes taking place in the interiors of late-type dwarfs, and this paper investigates the use of neutral...

    Construction of coronal hole and active region magnetohydrostatic solutions in two dimensions: Force and energy balance
    Coronal holes and active regions are typical magnetic structures found in the solar atmosphere. We propose several magnetohydrostatic equilibrium solutions that...

    Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy γ-rays
    Aims: The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) γ-ray emitter by MAGIC, is one of the few non-blazar active galactic...

    Contribution of the disk emission to the broad emission lines in AGNs: Two-component model
    We present an investigation of the structure of the emission line region in a sample of 12 single-peaked Active Galactic Nuclei (AGNs). Using the high...

    Convection in the atmospheres and envelopes of turnoff and giant branch stars of globular clusters
    We explore the dependence of {T_eff}'s and colors of stellar models on the treatment of over-adiabatic convection, both in the atmosphere and in the interior...

    Convective core sizes in rotating massive stars. I. Constraints from solar metallicity OB field stars
    Context. Spectroscopic studies of Galactic O and B stars show that many stars with masses above 8 M ⊙ have been observed in the Hertzsprung-Russell (HR) diagram...
