Characterizing bar structures : application to NGC 1300 , NGC 7479 and NGC 7723
Detailed surface photometry has been carried out for three barred galaxies with use of high resolution CCD broadband images in the B, V and I bands. Using azimuthal luminosity profiles and their decomposition into Fourier Series, the structural parameters (length and strength) of the bars in the three galaxies have been obtained. We have also inferred the corotation radii (CR) using information...
متن کاملPhotometric and kinematic studies of open star clusters III . NGC 4103 , NGC 5281 , and NGC 4755 ⋆ , ⋆ ⋆
We present CCD photometry and proper motion studies of the three open star clusters NGC4103, NGC5281, and NGC4755 (κ Cru). By fitting isochrones to the colour magnitude diagrams, we found that all three objects are young open star clusters with ages of at most t = 45 Myr. They are located at distances from approx. 1600 pc to 2200 pc, derived from distance moduli (m−M)0 ranging from 11 mag to 12...
متن کاملThe velocity field of the barred spiral galaxy NGC 1300 revisited ?
The re-reduction, described in Jörsäter & van Moorsel (1995), of NGC 1300 VLA H i observations, originally obtained by M. England, motivates a new analysis of the velocity field and rotation curve. Fitting tilted ring models to the H i velocity data, we find the new values for the orientation parameters of NGC 1300 to be PAlon = 267◦ ± 2◦ and i = 35◦ ± 5◦. Subsequently, the H i rotation curve i...
متن کاملGas Dynamics of NGC 4472
We present preliminary results from a 100 ks XMM-Newton observation of the hot gas in the nearby massive early-type galaxy NGC 4472. This galaxy is the central member of a group of galaxies that is believed to be falling into the Virgo cluster. We find several structures in the gas indicative of a previous epoch of nuclear activity and of a complex interaction with the ICM of the Virgo cluster....
متن کاملOrbital dynamics of three-dimensional bars: III. Boxy/Peanut edge-on profiles
We present families, and sets of families, of periodic orbits that provide building blocks for boxy and peanut (hereafter b/p) edge-on profiles. We find cases where the b/p profile is confined to the central parts of the model and cases where a major fraction of the bar participates in this morphology. A b/p feature can be built either by 3D families associated with 3D bifurcations of the x1 fa...
