    The Optical Spectral Line List of RR Telescopii
    The symbiotic nova RR Telescopii has been observed with the 1.5 m telescope of the Cerro Tololo Inter-American Observatory (CTIO), using the 1.5 m bench-mounted...

    The optical variability of 3C 345
    The behavior of the light curve of 3C 345 is analyzed using all B magnitudes available in the literature, thus extending the number of points in the compiled...
  • Publication
    The optical variability of 3C 345
    B-magnitudes have been compiled from the literature for 3C 345, covering a period from 1965 to 1980, 905 values in all. Since the last major study of the light...

    The optical warp of NGC 5907
    The optical warps of NGC 5907 is studied by means of CCD photometry, for the U and I filters, as well as for a narrow band filter centered at H-alpha. The...

    The Optical/IR Counterpart of the 1998 July 3 Gamma-Ray Burst and Its Evolution
    We imaged the X-ray error box of GRB 980703, beginning 22.5 hr after the gamma-ray event, in both the optical R and near-infrared H bands. A fading optical/IR...

    The Orbit and Companion of PSR J1622-0315: Variable Asymmetry and a Massive Neutron Star
    The companion to PSR J1622-0315, one of the most compact known redback millisecond pulsars, shows extremely low irradiation despite its short orbital period. We...
  • Publication
    The Orbit and Origin of the Ultra-faint Dwarf Galaxy Segue 1
    We present the first proper motion measurement for an ultra-faint dwarf spheroidal galaxy, Segue 1, using data from the Sloan Digital Sky Survey (SDSS) and the...
  • Publication
    The orbit of the close spectroscopic binary varepsilon Lup and the intrinsic variability of its early B-type components
    We subjected 106 new high-resolution spectra of the double-lined spectroscopic close binary varepsilon Lup, obtained in a time-span of 17 days from two...
  • Publication
    The orbital period of CY UMa
    We present intermediate resolution spectroscopy of the dwarf nova CY UMa in quiescence. From the radial velocities of the Hα emission, we derive an orbital...
