A series of about forty long-slit spectra of Halley's comet has been secured in the optical wavelength region, using different instruments, at resolution ranging from 0.05 to 1.6 nm. The interval of heliocentric distance r covered by these observations is 1.7 to 0.9 a.u. before perihelion, while r = 0.95 a.u. after perihelion. The main characteristics of the pre-perihelion spectra are described. In particular, some emissions due to the OH[SUP]+[/SUP] (0,1) and CH[SUP]+[/SUP](1,0) bands have been detected for the first time. [less ▲]

Spectra of P/Halley were taken at very high resolution (0.15A) to evaluate contamination of the forbidden oxygen doublet by NH2 features at low resolution. Comparison is made with other bright comets. Appreciable variations are found in the NH2/(OI) ratio and in the relative intensities of the NH2 emissions themselves. The accuracy obtained on the oxygen abundance derived from the (OI) lines is discussed. Mapping of these emissions over the coma is required to correctly remove any important NH2 contribution at low resolution. This should also provide information on the origin of the oxygen atoms in the 1D level. [less ▲]

Photoelectric observations of P/Halley were carried out during several weeks between 15 Sept. 1985 and 25 June 1986. All measurements were made using the standard IAU/IHW cometary filters. Large amplitude night-to-night changes over periods of several days superimposed on the general trend of slow brightness variation were seen. Smooth and irregular variations with a range up to 0.2 mag on time scales of several hours were observed. Present photometric scans of comet Halley through the various filters are presented. Successive integrations were made every 5 arc sec, radially from the center out to a distance of 5 arcmin, essentially along the sunward-antisunward direction and in the direction perpendicular to it.

Afin d'élimine(r les salissures qui se développent sur les parois des dispositifs de refroidissement, des chlorations sont pratiquées régulièrement dans les centrales électriques. La présente étude concernait la problématique des chlorations à la centrale de Tihange 1 et avait pour objectifs : i) de comprendre les différents processus physico-chimiques qui se passent à l'intérieur des circuits de la centrale et dans la Meuse; ii) de déterminer de quelle manière les processus de chloration ont un impact sur la qualité des eaux de la Meuse et sur le fonctionnement de son écosystème [less ▲]

Differential uvby observations of Spica are presented and analyzed. No coherent short-period light or colour index variations are found. An analysis of the ellipsoidal light variation leads to a new value of the radius of the primary component, which agrees very well with the radius determined by means of the Narrabri stellar intensity interferometer. The analysis also shows that the photometric data are consistent with the spectrographic period of the rotation of the line of apsides. In addition, recent hypotheses concerning the apparently extinct pulsations of the primary component are discussed. It is pointed out that the enhanced surface helium models of Cox (1985) predict pulsation constants substantially larger than the pulsation constant derived from the observationally determined mass and radius.
