  • Molecular and low excitation emission in high mass post-main-sequence nebulae
    A broad range of type I post-main-sequence nebulae have been mapped and studied spectroscopically in the J = 1 - 0, J = 2 - 1, and J = 3 - 2 transitions of CO using the 12-m antenna at Kitt Peak and the 45-m facility at the Nobeyama Radio Observatory. CO J = 2 - 1 emission associated with NGC 3132 and NGC 6445 is detected; the location of CO J = 1

  • Estimating the Degradation of Brightness Power Spectra of Solar Granulation from Images Outside the Disk Centre
    A method is presented to estimate the influence of the atmospheric turbulence and the telescope on the mean power spectra of the granulation brightness distribution at positions outside the disk centre, derived using the determination of Fried's parameter. The procedure is based on the differential degradation suffered by the directions

  • A Polarized Accretion Disk Flare in OJ:287
    A very rapid swing in the polarization position angle (PA) in the optical region was observed in blazar OJ 287 during one night of our five nights UBVRI photopolarimetric monitoring in January 1991 with the Nordic Optical Telescope. During this PA swing the flux increased ~40% in five hours, while the polarization level was very stable and quite

  • A 6.5-day periodicity in the recurrent nova V404 Cygni implying the presence of a black hole
    Two years after its outburst in 1989, the William Herschel Telescope has been used to find absorption features in V404 Cyg characteristic of a late G or early K star with a radial velocity curve of amplitude 211 +/- 4 km/s and period 6.473 +/- 0.001 days. The deduced mass function of 6.26 +/- 0.31 solar masses is a firm lower limit to the mass of
