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…

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…
