Accurate Parameters of the Mass Distribution in Spiral Galaxies: 1. Fabry - Perot Observations of NGC 5585

Sebastien Blais-Ouellette, Claude Carignan, Philippe Amram +1

Using the example of the Sd galaxy NGC 5585, it is shown that high resolution 2-D HII kinematical data are necessary to determine accurately the parameters of the mass distribution…

The Star Formation History of the Starburst Region NGC 2363 and its Surroundings

L. Drissen, J. -R. Roy, C. Robert +2

We present HST optical images and UV spectra, as well as ground-based near-infrared images of the high surface brightness giant HII region NGC 2363 (NGC 2366-I) and its surrounding…

An Investigation of the Large-scale Variability of the Apparently Single Wolf-Rayet Star WR 1

T. Morel, L. N. Georgiev, Y. Grosdidier +3

In recent years, much studies have focused on determining the origin of the large-scale line-profile and/or photometric patterns of variability displayed by some apparently single…

Do galaxy mergers form elliptical galaxies? A comparison of kinematic and photometric properties

P. A. James, C. Bate, M. Wells +2

We present near-IR K-band imaging and spectroscopy of a sample of galaxy mergers, which we use to derive light profile indices, absolute magnitudes and central velocity dispersions…

A subarcsecond resolution near-infrared study of Seyfert and `normal' galaxies: I. Imaging data

R. F. Peletier, J. H. Knapen, I. Shlosman +5

We present new high-resolution near-infrared observations in the J,H and K bands, obtained to study the properties of Seyfert host galaxies. The dataset consists of images in the t…

Angular momentum redistribution by waves in the Sun

Pawan Kumar, Suzanne Talon, Jean-Paul Zahn

We calculate the angular momentum transport by gravito-inertial-Alfvén waves and show that, so long as prograde and retrograde gravity waves are excited to roughly the same amplitu…

A 2.3-Day Periodic Variability in the Apparently Single Wolf-Rayet Star WR 134: Collapsed Companion or Rotational Modulation?

T. Morel, S. V. Marchenko, P. R. J. Eenens +8

We present the results of an intensive campaign of spectroscopic and photometric monitoring of the peculiar Wolf-Rayet star WR 134 from 1989 to 1997. This unprecedentedly large dat…
