  • HST/STIS spectra of alpha Cen A

    This table is part of a paper is which a study of the alpha Cen A spectrum recorded with the E140 grating by HST/STIS between 1140 and 1670{AA} is presented. In this spectrum...
  • The CORALIE survey for extrasolar planets. XII

    The paper summarizes the information gathered for 16 exoplanet candidates discovered with the CORALIE echelle spectrograph mounted on the Euler Swiss telescope at La Silla...
  • BVRIJK and velocities for MC Cepheids

    We present high precision and well sampled BVRIJK light curves and radial velocity curves for a sample of five (+1) Cepheids in the SMC. In addition we present radial velocity...
  • Deprojection of spiral galaxies

    We present two methods that can be used to deproject spirals, based on Fourier analysis of their images, and discuss their potential and restrictions. Our methods perform...
  • High-frequency polarization of Kuehr sources

    We have observed 250 of the 258 southern sources in the complete 5GHz 1Jy sample by Kuehr et al. (1981, Cat. ) using the Australia Telescope Compact Array (ATCA) at 18.5GHz....
  • Mount Stromlo Abell Cluster Supernova Search

    Table 1 lists SNe discovered by the Mount Stromlo Abell Cluster Supernova Search. The SNIa? were classified through the goodness of fit of the template light curves and hence...
  • Radial velocities of 10 Galactic Cepheids

    We present here the appendix to the paper with the new high precision radial velocities for a sample of Galactic Cepheids. The stars are: SU Cas, EV Sct, del Cep, CV Mon, U Sgr,...
  • Redshifts behind the Southern Milky Way

    As part of our efforts to unveil extragalactic large-scale structures behind the southern Milky Way, we here present redshifts for 764 galaxies in the Hydra/Antlia, Crux and...
  • UBVRI surface brightness of 26 bright galaxies

    The UBVRI images of 26 bright spiral galaxies were decomposed in disks and bulges. Correlations of the resulting structural parameters are investigated, giving clues to the...
  • Near-IR photometry of PMS stars in rho Oph

    The aim of this paper is to provide a measurement of the mass accretion rate in a large, complete sample of objects in the core of the star forming region rho Oph. The sample...
  • EIS: infrared observations of CDF-S and HDF-S

    This paper presents infrared data obtained from observations carried out at the ESO 3.5m New Technology Telescope (NTT) of the Hubble Deep Field South (HDF-S) and the Chandra...
  • RR Tel JHKL photometry 1975-2002

    A set of photometric observations of the symbiotic nova RR Tel in different wavelength bands - visual from 1949 to 2002 and near-infrared (JHKL) from 1975 to 2002 - are...
  • Spectra of Nova Scuti 2005 N.2 (V477 Sct)

    Our CCD photometry of Nova Scuti 2005 N.2 (=V477 Sct) shows it to be a very fast nova, which is characterized by t_2_=3 and t3_=_6 days, affected by a E(B-V)>=1.3mag...
  • BV light curve of V781 Tau

    We analyze light curves of the W UMa type eclipsing binary V781 Tauri from three epochs and radial velocity curves from two epochs simultaneously, including previously...
  • SCUBA ultracompact HII regions

    We present a SCUBA submillimetre (450 and 850{mu}m) survey of the environment of 105 IRAS point sources, selected from the Wood and Churchwell (1989ApJS...69..831W) and Kurtz et...
  • UBV(RI)c photometry of 4 open clusters

    Ages derived from the low mass stars still contracting onto the main sequence often differ from ages derived from the high mass ones that have already evolved away from it. We...
  • Extended envelopes around Galactic Cepheids II.

    We present the results of long-baseline interferometric observations of the classical Cepheids Polaris and delta Cep in the near infrared K' band (1.9-2.3 microns), using the...
  • HARPS observations of nine galactic Cepheids

    The ratio of pulsation to radial velocity (the projection factor) is currently limiting the accuracy of the Baade-Wesselink method, and in particular of its interferometric...
  • CCD positions for eight Jovian irregular satellites

    The astrometric positions of eight irregular Jovian satellites are given for the oppositions of the planet from 1995 to 1999. These positions were measured on 204 CCD frames...
  • Line-strength indices in IC 4200

    Optical spectroscopy, imaging and radio observations of the galaxy IC 4200 are analysed in order to determine the formation history of the galaxy. The two tables available...
