Modelling galactic spectra - II. Simultaneous study of stellar dynamics and stellar mix in NGC 3258.
DE BRUYNE V., DE RIJCKE S., DEJONGHE H. and ZEILINGER W.W.
Abstract (from CDS):
This paper reports on a dynamical stellar population study in NGC 3258, based on spectra in two different wavelength regions, the near-infrared Ca ii triplet around 8600 Å and the Ca H and K lines around 3900 Å. These absorption lines have discriminating power towards various stellar types. The dynamical model shows an increase in dwarfs (represented by G2V stars) towards the centre. Most of the rotation in the model is delivered by the giants (represented by M1III stars). Moreover, the different models that were considered indicate that establishing a potential for a galaxy is dependent on the wavelength range used for the modelling.
