1998A&A...335..912K Seyfert galaxies and environment: Seyferts in galaxy pairs and groups. Kelm B., Focardi P., Palumbo G.G.C. Received 20 May 1997/Accepted 14 April 1998 Abstract. The occurrence of Seyfert galaxies in 6 samples representative of different cosmological environments (i.e. isolated pairs, compact and loose groups) is analysed. To avoid biases linked to subjective sample selection criteria only canonical samples, taken from the literature, are considered. It is found that the average frequency of Seyferts in all samples, is near 2%. Most Seyferts lying in pairs and compact groups show disturbed morphological appearance, whilst in loose groups disturbed and ``isolated'' Seyferts have roughly the same proportion. Then, within each sample, structures which host a Seyfert are compared to structures which do not. No appreciable differences regarding dynamical properties are found. Key words: galaxies: interactions - galaxies: Seyfert
