  • Jets, Knots, and Tails in Planetary Nebulae: NGC 3918, K1-2, and Wray 17-1

    We analyze optical images and high-resolution, long-slit spectra of three planetary nebulae that possess collimated, low-ionization features. NGC 3918 is composed of an inner, spindle-shaped shell mildly inclined with respect to the plane of the sky. Departing from the polar regions of this shell, we find a two-sided jet expanding with velocities

  • JHK photometry of Vega-type and PMS stars (Eiroa+, 2001)

    File table1.dat contains near-infrared JHK magnitudes of a sample of 18 Vega-like and post-T Tauri stars observed by the EXPORT collaboration. File table2.dat contains near-infrared JHK magnitudes of a sample of 4 pre-main sequence stars observed by EXPORT. The data were taken during four observing runs in the period May 1998 to January 1999. (3

  • KIC 4768731: a bright long-period roAp star in the Kepler field

    We report the identification of 61.45 d-1 (711.2 μHz) oscillations, with amplitudes of 62.6 μmag, in KIC 4768731 (HD 225914) using Kepler photometry. This relatively bright (V = 9.17) chemically peculiar star with spectral type A5 Vp SrCr(Eu) has previously been found to exhibit rotational modulation with a period of 5.21 d. Fourier analysis

  • Kinematic profiles of dumbbell galaxies with twisted radio jets.

    We study the orbital properties of dumbbell galaxies which harbor twisted radio jets. Velocity and velocity dispersion profiles for four dumbbell pairs (3C66B, 3C75, 3C449, 0326+39) are presented. We analyze optical CCD images in search of isophote off-centering and large isophote twists. Combining the kinematic and isophotal information, we

  • Knots in the Outer Shells of the Planetary Nebulae IC 2553 and NGC 5882

    We present images and high-resolution spectra of the planetary nebulae IC 2553 and NGC 5882. Spatiokinematic modeling of the nebulae shows that they are composed of a markedly elongated inner shell and of a less aspherical outer shell expanding at a considerably higher velocity than the inner one. Embedded in the outer shells of both nebulae are

  • L iquid Crystal Variable Retarders For Aerospace Applications

    Polarization modulators based on Liquid Crystal Variable Retarders (LCVRs) are envisaged as a powerful and versatile solution whose main advantage is the lack of mechanisms (i.e. rotating plates). An extensive test campaign has been carried out in order to demonstrate the feasibility of the LCVRs for the IMaX/SUNRISE magnetograph in environmental
