Boxy/peanut shaping of a mature galactic bar in action-angle space
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova +1
We study vertical resonant trapping and resonant heating of orbits. These two processes both lead to the growth of a boxy/peanut-shaped bulge in a typical -body model. For the f…
Isochrone Fitting of Galactic Globular Clusters -- VI. High-latitude Clusters NGC5024 (M53), NGC5053, NGC5272 (M3), NGC5466, and NGC7099 (M30)
G. A. Gontcharov, S. S. Savchenko, A. A. Marchuk +7
We fit various colour-magnitude diagrams (CMDs) of the high-latitude Galactic globular clusters NGC\,5024 (M53), NGC\,5053, NGC\,5272 (M3), NGC\,5466, and NGC\,7099 (M30) by isochr…
Positive Lynden-Bell derivative as a ticket to the bar trap?
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova
We have translated the results of -body simulations of one barred model into the language of action variables and frequencies. Using this language, we analysed the behaviour of…
Galaxies decomposition with spiral arms -- II: A multiwavelength case study of M 51
Alexander A. Marchuk, Ilia V. Chugunov, George A. Gontcharov +7
Spiral structure can contribute significantly to a galaxy's luminosity. However, only rarely are proper photometric models of spiral arms used in decompositions. As we show in the…
Isochrone fitting of Galactic globular clusters -- V. NGC6397 and NGC6809 (M55)
George A. Gontcharov, Charles J. Bonatto, Olga S. Ryutina +8
We fit various colour-magnitude diagrams (CMDs) of the Galactic globular clusters NGC\,6397 and NGC\,6809 (M55) by isochrones from the Dartmouth Stellar Evolution Database (DSED) a…
