  • Multifrequency Analysis of the New Wide-Separation Gravitational Lens Candidate RX J0921+4529
    We report the discovery of a new two-image gravitational lens candidate. The system RX J0921+4529 contains two zs=1.66 quasars separated by 6.93" with an H-band magnitude difference of Δm=1.39. The HST NIC2 H-band images reveal an H=18.2 spiral galaxy between the quasar images, which is probably a member of a zl=0.32 X-ray cluster centered on the

  • Magnetic field oscillations in sunspots and active regions
    In order to investigate the oscillatory behaviour of the magnetic field in sunspots and pores, full Stokes measurements of 1.56 μm iron lines have been performed using the Tenerife Infrared Polarimeter (TIP) at the German Vacuum Tower Telescope on Tenerife. As expected, velocity oscillations have power peaks at five minutes. First results for

  • LOWL p-mode frequencies and their variation with solar activity
    We present an analysis of the frequency shift and the even terms of the frequency splitting coefficients carried out using six years of LOWL data, starting in 1994. The temporal variations, and their dependences with the frequency and degree are addressed. The results are consistent with previous analysis.

  • Low-Ionization Structures in Planetary Nebulae: Confronting Models with Observations
    Around 50 planetary nebulae (PNs) are presently known to possess ``small-scale'' low-ionization structures (LISs) located inside or outside their main nebular bodies. We consider here the different kinds of LISs (jets, jetlike systems, symmetrical and nonsymmetrical knots) and present a detailed comparison of the existing model predictions with the
