    Detections of diffuse interstellar bands toward the SN 1987A in the Large Magellanic Cloud

    The authors report the results of high resolution and high S/N observations of diffuse interstellar bands (DIBs) towards SN 1987A in the LMC. For the first time...

    Interacting binary galaxies. V - NGC 4782/4783 (3C 278): Unbound colliders, not a supermassive pair

    The authors have determined the masses and orbital parameters for the galaxies in the strongly interacting binary NGC 4782/4783 by finding a numerical...

    Interpreting asymmetric line profiles in merger remnants

    Absorption line profile asymmetries in ellipticals with peculiar core kinematics, and their role as diagnostics of mergers, are analyzed using self-consistent...

    Interstellar and intergalactic gas in the direction of SN 1993J in M81

    During the first few nights following its discovery, we observed the interstellar Ca II and Na I lines towards supernova 1993J at high spectral resolution (full...

    Long slit spectroscopy of NGC 5506

    The galaxy NGC 5506 hosts an active nucleus, that presents characteristics that are intermediate between Sy1 and Sy2. We discuss long slit spectra of NGC 5506...

    LTE polarized radiative transfer through interlaced atmospheres

    We show that the solution of the radiative transfer equation (RTE) through a line of sight that pierces several times two alternate atmospheres can be obtained...

    Observed differences between large and small sunspots

    We confirm recent results about the differences in temperature and magnetic field strength between the umbra of large and small sunspots. Five Stokes I- and V...

    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...

    Solar core rotation

    Data from solar line of sight velocity measurements are presented to demonstrate the existence of a synodic signal with a 6.5 m/sec amplitude. Recordings of...
