  • Spectroscopic Classification of Late-M and L Field Dwarfs
    We present spectra for 12 new ultracool dwarfs found in the DENIS infrared survey. Seven of them have spectral types at the bottom of the M-class (M8-M9.5), and the other five belong to the cooler ``L'' class. We also present spectra for the two new L dwarfs found by the EROS 2 proper-motion survey. We introduce a scheme for L dwarf classification

  • Photometry of UCM galaxies (Perez-Gonzalez+, 2000)
    We present Johnson B CCD photometry for the whole sample of galaxies of the Universidad Complutense de Madrid (UCM) Survey Lists I and II (Cat. and ). They constitute a well-defined and complete sample of galaxies in the Local Universe with active star formation. The data refer to 191 S0 to Irr galaxies at an averaged redshift of 0.027, and

  • Phase Differences and Gains between Intensity and Velocity in Low-Degree Acoustic Modes Measured by SOHO
    Helioseismic instruments aboard SOHO are making possible a more accurate way of investigating the internal structure of the Sun. Making use of the different techniques and characteristics of these instruments, it is possible to measure solar oscillations as variations of the photospheric velocity (GOLF, MDI) or as irradiance and radiance

  • On the parallax of WD 0346++246: a halo white dwarf candidate
    We present a parallax measurement for the very cool degenerate WD 0346+246, the serendipitous discovery of which was reported by Hambly et al. We find an absolute parallax of 36+/-5mas, yielding a distance estimate of 28+/-4pc. The resulting absolute visual magnitude of the object is MV=16.8+/-0.3, making it the second-lowest luminosity white dwarf

  • Homotopy of state orbits
    Let M be a von Neumann algebra, f a faithful normal state and denote by M^f the fixed point algebra of the modular group of f. Let U_M and U_{M^f} be the unitary groups of M and M^f. In this paper we study the quotient U_M/U_{M^f} endowed with two natural topologies: the one induced by the usual norm of M (called here usual topology), and the one
