    Self-absorption effects in the equivalent width of the spectral lines in a neon microwave plasma at atmospheric pressure
    The ratio of the intensities is related to the emph{equivalent width}, W, of the spectral lines, which shape is approximated to a Voigt function resulting from...

    Self-consistent models for Coulomb heated X-ray pulsar atmospheres
    Calculations of accreting magnetized neutron star atmospheres heated by the gradual deceleration of protons via Coulomb collisions are presented. Self...

    Self-sustaining galactic winds in spiral galaxies with starburst nuclei
    In the circumnuclear zones of the disks of some spirals there is an absence of neutral interstellar hydrogen. A model is devised in which gaseous outflow is...

    Sensitivity of oscillation frequencies to temporal variations in the tachocline region
    We have analyzed the differences in the oscillation eigenfrequencies measured over four years of GONG, SOI/MDI and LOWL observations (1996 to 1999). We have...
