Astrophysical: Infrared photometry

  • Publication
    Near-infrared photometry and spectrophotometry of two unusual novae
    We present near IR photometry and spectrophotometry of two unusual novae observed in 1991: Nova Herculis and Nova Scuti. Both are seen to have unusual spectral...
  • Publication
    Near-infrared photometry of high redshift quasars
    NIR (JHK) photometry of six quasars with redshifts ranging from 3 to 3.78 is reported. None of these objects has previously been observed in the IR. Their NIR...
  • Publication
    Near-infrared photometry of red giant and horizontal branch stars in M4
    Near-infrared photometry for the red-giant and horizontal branches in M4, obtained with the InSb detector mounted on the 1.54-m Tenerife Infrared flux collector...
  • Publication
    Optical and infrared observations of the H II region S201
    Optical spectroscopy, H-alpha interferometry, and near-IR mapping and photometry of the bipolar H II region S201 are reported. The observations are used to...
  • Publication
    Optical spectroscopy and near-infrared mapping of S 106
    The bipolar outflow region S 106 is studied with optical spectroscopy and IR mapping techniques. The physical conditions in the ionized region, the density...

    Parameter estimates for the orbits of M 32 and NGC 205 about the centre of mass of the M 31 system
    The authors used simple kinematic, dynamic and geometrical assumptions to infer the orbital parameters of M32 and NGC 205 about M31. They find that both...
  • Publication
    Photometric study of ER VUL
    The authors present simultaneous UBVRI and infrared JHKL light curves of the short-period RS CVn system ER Vul, and study both the mean level and depths of...
  • Publication
    Search for the near infrared counterparts of compact H II regions and/or H2O masers.
    The authors present the preliminary results of a search for near-infrared counterparts of compact H II regions and/or H2O masers in the Galactic Plane, probably...
  • Publication
    Spot activity and circumstellar matter in II Peg.
    Infrared and V band photometry of the RS CVn system II Peg, carried out in 1984 and 1986, has been analysed with a simple model in order to follow the evolution...
