    Variable Very-High-Energy Gamma-Ray Emission from the Microquasar LS I +61 303
    Microquasars are binary star systems with relativistic radio-emitting jets. They are potential sources of cosmic rays and can be used to elucidate the physics...

    Variation in sunspot properties between 1999 and 2011 as observed with the Tenerife Infrared Polarimeter
    Aims: We study the variation in the magnetic field strength and the umbral intensity of sunspots during the declining phase of the solar cycle No. 23 and in the...
  • Publication
    Variation in sunspot properties between 1999 and 2014
    Aims: We study the variation in the magnetic field strength, area, and continuum intensity of umbrae in solar cycles 23 and 24. Methods: We analyzed a sample of...
  • Publication
    Variation of coronal line widths on and off the disk
    We present observations of a Mg X 625 Å coronal line, obtained with the CDS instrument on SoHO, extending from the disk part of the coronal hole to ~ 90 000 km...
  • Publication
    Variation of Fluxes of RR Tel Emission Lines Measured in 2000 with Respect to 1996
    The aim of this work is to make available unpublished non-Fe+ emission line fluxes from optical spectra of the symbiotic nova RR Tel, which were taken in 2000...
  • Publication
    Variation of Galactic Bar Length with Amplitude and Density as Evidence for Bar Growth over a Hubble Time
    Ks-band images of 20 barred galaxies show an increase in the peak amplitude of the normalized m=2 Fourier component with the R25-normalized radius at this peak...
  • Publication
    Variation of the frequencies of very low L p-modes
    Radial velocity observations performed using a resonant scattering instrument from 1980 to 1993 at the Observatorio del Teide have been used to calculate the...
  • Publication
    Variation of the low-degree solar acoustic mode parameters over the solar cycle
    VIRGO/SPM is a helioseismic sunphotometer on board SOHO that observes the disk-integrated sunlight irradiance at three different colors (red, green, and blue)...
  • Publication
    Variation of the stellar initial mass function in semi-analytical models. III. Testing the cosmic-ray regulated integrated galaxy-wide initial mass function
    Context. In our previous work, we derived the CR-IGIMF, which is a new scenario for a variable stellar initial mass function (IMF) that combines numerical...
