Abstract: Non-axisymmetric components, such as spirals and central bars, play a major role in shaping galactic discs. An important aspect of the disc secular evolution driven by these perturbers is the radial migration of stars. It has been suggested recently that migration can populate a thick-disc component from inner-disc stars with high vertical energies. Since this has never been demonstrated in simulations, we study in detail the effect of radial migration on the disc velocity dispersion and disc thickness, by sep… Show more

“…This naturally results in disc flaring, as shown in Fig. 7 by Minchev et al (2012a). We explained this as the conservation of vertical action as opposed to conservation of the vertical energy assumed before.…”

“…More detailed dynamical studies Minchev et al 2012a;Vera-Ciro et al 2014) have more recently shown that migration does not contribute to any significant level to disc thickening, but on the opposite, it suppresses flaring when external perturbations are included (Grand et al 2016;Minchev et al 2014a). This is discussed further in Sect.…”
