  • Mass outflow and its consequences in the circumnuclear zones of galaxies
    Spectroscopic and photometric observations are used to determine the distributions of gas and the kinematics in the central zones of a number of spirals. In addition to a ring structure in the gas, there is often found a measurable expansion with high radial velocity near the nucleus. A significant correlation is noted between the absence of

  • Lithium and rotation in the Hyades late F and G stars
    Selecting stars with previously measured or estimated rotational periods we have measured equivalent widths of the Li doublet (6708 A) in 8 stars of the Hyades late main sequence and, combining our data with literature values, derive a homogeneous set of Li abundances. The graph of Li against period is monotonic, taking, not surprisingly, a similar

  • An explanation for the Stokes V asymmetry in solar faculae
    The asymmetry in the Stokes V profile observed in solar faculae can be explained by assuming that the magnetic field increases with height while downflow speed decreases. The MHD compatibility of such solution is briefly discussed together with an observational test for that possibility.

  • Parameter estimates for the orbits of M 32 and NGC 205 about the centre of mass of the M 31 system
    The authors used simple kinematic, dynamic and geometrical assumptions to infer the orbital parameters of M32 and NGC 205 about M31. They find that both galaxies rotate in a retrograde sense compared to M31 indicating a possible common origin independent of the mother galaxy. Their periods, each ≅108yr, and their orbital radii, ≅12 kpc, are

  • On the application of iteration factors for temperature correction in stellar atmospheres
    The authors present an improved iterative method for deriving temperature corrections in stellar atmospheres. At each step of iteration, the procedure computes, from the current values of the radiation field, a set of depth-dependent factors, averaged over angles and frequencies. Even a crude initial estimate of the radiation field leads to a

  • Narrow band 1 micron-4 micron infrared photometry of 176 stars
    Observations of 176 stars have been obtained by filter photometry over the 1-4 micron range at the Observatorio del Teide in Tenerife. Measurements for Jn, Kn, and Ln relative to Vega are presented, along with the probable errors of those stars observed for several nights during two of the three observing sessions. Mean quoted probable errors of 0
