AGNs with composite spectra II. Additional data
A. C. Goncalves, M. -P. Veron-Cetty, P. Veron
In a previous paper (Veron et al. 1997) we presented medium resolution (3.4 A FWHM) spectroscopic observations of 15 "transition objects", selected for having an ambiguous location…
On the QSO content of the First Byurakan Survey and the completeness of the Palomar Green Survey
P. Veron, A. M. Mickaelian, A. C. Goncalves +1
The second part of the First Byurakan Survey is aimed at detecting all bright (B < 16.5) UV-excess starlike objects in a large area of the sky. By comparison with major X-ray and r…
The emission-line spectrum of KUG 1031+398 and the Intermediate Line Region controversy
A. C. Goncalves, P. Veron, M. -P. Veron-Cetty
We present results based on the analysis of optical spectra of the Narrow-Line Seyfert 1 (NLS1) galaxy KUG 1031+398, for which evidence was reported of a line-emitting region "inte…
Preliminary results of dark-speckle stellar coronography
A. Boccaletti, A. Labeyrie, R. Ragazzoni
The dark-speckle method (Labeyrie 1995) combines features of speckle interferometry and adaptive optics to provide images of faint circumstellar material. We present preliminary re…
Determination of T_eff and log g for A0 type stars and its impact on the interpretation of the HR diagram with the HIPPARCOS results
M. Gerbaldi, R. Faraggiana, R. Burnage +3
The determination of the ``Fundamental Parameters'' T_eff and log g for a set of dwarf A0-type stars is discussed in terms of consistency when comparing these values determined thr…
The Structure of Radiative Shock Waves. I. The method of global iterations
Yu. A. Fadeyev, D. Gillet
The structure of steady plane-parallel radiative shock waves propagating through the hydrogen gas undergoing partial ionization and excitation of bound atomic states is investigate…
