Eta Carinae: Binarity Confirmed

Augusto Damineli, Andreas Kaufer, Bernhard Wolf +3

We report the recovery of a spectroscopic event in eta Carinae in 1997/98 after a prediction by Damineli (1996). A true periodicity with P = 2020+-5 days (0.2% uncertainty) is obta…

Two Galaxy Clusters: A3565 and A3560

C. N. A. Willmer, M. A. G. Maia, S. O. Mendes +4

We report 102 new redshifts and magnitudes for a sample of galaxies to RF ~ 15.5 mag in a 2.17 deg x 2.17 deg region centered on the galaxy IC 4296, the most luminous member of the…

The abundance of nitrogen in starburst nucleus galaxies

R. Coziol, R. E. Carlos Reyes, S. Considere +2

We show that the excess of nitrogen emission observed in a large sample of Starburst Nucleus Galaxies (SBNGs) can only be explained at a given metallicity by an overabundance of ni…

Spectropolarimetry of the Luminous Narrow-Line Seyfert Galaxies IRAS 20181-2244 and IRAS 13224-3809

Laura E. Kay, A. M. Magalhaes, F. Elizalde +1

We observed the narrow-line Seyfert 1 galaxies IRAS 20181-2244 and IRAS 13324-3809 with a new spectropolarimeter on the RC spectrograph at the CTIO 4m telescope. Previously it had…
