Hα Kinematics of the Isolated Interacting Galaxy Pair KPG 486 (NGC 6090)
Rosado, M.; Sánchez-Cruces, M.; Sardaneta, M. M.
In optical images, the barely studied isolated interacting galaxy pair KPG 486 (NGC 6090) displays similar features to the Antennae (NGC 4038/39) galaxy pair. To compare the distribution of ionized hydrogen gas, morphology and kinematic and dynamic behaviour of both galaxy pairs, we present observations in the Hα emission line of NGC 6090 acquired…
Spectral Behavior of the Symbiotic Nova HM Sge in the Ultraviolet
Sanad, M. R.; Abdel-Sabour, M. A.
Ultraviolet observations of the symbiotic nova HM Sge were obtained from the International Ultraviolet Explorer (IUE) through the interval from 1980 - 1992. Three line profiles demonstrating the variations of some emission lines at different dates are presented. We determined the reddening of HM Sge from the 2200 Å absorption feature; the estimate…
