As galáxias espirais normais possuem um núcleo, disco, bojo, halo e braços espirais. Esses sistemas despertam muita curiosidade, atração e questionamentos científicos e consequentemente, muitos estudos e técnicas são propostas para análise d

Determining the portion obscured by clouds in the night sky recorded in an image from a meteor monitoring station can be useful to help in the discussion and analysis of studies in this area. Thereby, this work presents a proposal to quantitatively m

The recent detection of a double Red Giant Branch in the optical color-magnitude diagram (CMD) of the bulge globular cluster HP1 (Ortolani et al. 1997), a more populated metal-poor steep one corresponding to the cluster itself, and another metal-rich

We investigate the interaction effects in the stellar and gas kinematics, stellar population and ionized gas properties in the interacting galaxy pair AM1209-292, composed by NGC4105 and NGC4106. The data consist of long-slit spectra in the range of

One of the algebraic potentials most commonly used to represent a galactic bar in the stellar orbits integration is the Ferrers potential. Some researchers may be inclined to implement a numerical differentiation for it in the motion or variational e

This paper aims to verify the influence of the bar, its pattern speed (Ω_b) and its rate of growth on the stability of the orbits in gravitational potentials. We studied the nature of the orbits in potentials representing galaxies with growing bars

In this study we define a new sample of distant powerful radio galaxies in order to study their host-galaxy properties and provide targets for future observations of HI absorption with new radio telescopes and to understand the fuelling and feedback
