Low Redshift BAL QSOs in the Eigenvector 1 Context
Marziani, P.; Zamanov, R.; Braito, V. +4 more
We attempt to characterize the geometry of Broad Absorption Line (BAL) QSOs by studying a low redshift sample of 12 sources. We find that the majority of these sources are Population A quasars as defined in Sulentic et al. (2000a, broad HbetaFWHM ≤ 4000 km s(-1) ). A possible correlation between terminal velocity and absolute V magnitude suggests …
uvby - β Photoelectric Photometry of the Open Cluster α Per
Sareyan, J. -P.; Peña, J. H.
Absolute photoelectric photometry of stars in the direction of the Open Cluster α Per has been secured and is presented along with an analysis reinforced with all the available data in Strömgren uvby-β photometry compiled from the literature. Cluster membership is analyzed and the physical characteristics of the stars have been deduced. The member…
