  • The quiet Sun magnetic field observed with ZIMPOL on THEMIS. I. The probability density function

    Context: The quiet Sun magnetic field probability density function (PDF) remains poorly known. Modeling this field also introduces a magnetic filling factor that is also poorly known. With these two quantities, PDF and filling factor, the statistical description of the quiet Sun magnetic field is complex and needs to be clarified. Aims: In the

  • The rapid fading of V1647 Orionis: the sudden end of a FUor-type eruption?

    The young eruptive star V1647 Ori started a rapid fading in October 2005 and now is only 1 mag above the pre-outburst level. Colour changes indicate that the fading is not due to increasing extinction.

  • The Rise of Twisted Magnetic Tubes in a Stratified Medium

    First results from a two-dimensional numerical study of the buoyant rise of twisted magnetic flux tubes in the solar convection zone are presented. We show in detail the process by which the transverse component of the field can suppress the splitting of the rising tube into two vortex filaments. For the suppression to be effective, the pitch angle

  • The Role of the Accretion Disk, Dust, and Jets in the IR Emission of Low-luminosity Active Galactic Nuclei

    We use recent high-resolution infrared (IR; 1-20 μm) photometry to examine the origin of the IR emission in low-luminosity active galactic nuclei (LLAGN). The data are compared with published model fits that describe the spectral energy distribution (SED) of LLAGN in terms of an advection-dominated accretion flow, truncated thin accretion disk, and

  • The role of the tropopause layer altitude on the infrared quality of astronomical sites

    The infrared sky quality is an important parameter to take into account for the evaluation of astronomical sites. The traditional idea of considering higher altitude sites as better for infrared astronomical observations than sites at lower altitudes is not in agreement with observational data. It has been shown that the observational infrared
