SUMMARY:The Milky Way galaxy: from the radial migration of stars to GAIA DR
 2 data analysis
DESCRIPTION:The Milky Way galaxy: from the radial migration of stars to GAI
 A DR2 data analysis\nDr. Roman Nagy\n\n\n\n\nThe radial migration of stars
  in the Galactic disc has been intensively studied during the last two dec
 ades. Many papers, investigating the effects of the Galactic bar, the spir
 al pattern and their resonances on the radial migration of stars and mixin
 g of the Galactic disc, have been published in the recent years. In the fi
 rst part of the presentation, we will focus on the results of our simulati
 ons. We will compare two approaches, the first one considers the NFW dark 
 matter halo, the second one takes into account the non-Newtonian gravity b
 ased on the paper by McGaugh et al. (2016).\nThe second part of the talk w
 ill be dedicated to the research conducted during my ERASMUS+ stay at IAC.
 In collaboration with Dr. Martín López-Corredoira and his te
 am, we have focused on the analysis of the kinematic maps of GAIA-DR2. We 
 have used maps by López-Corredoira & Sylos Labini (2019), 
 providing data for extended range of Galactocentric distances R<20kpc. 
 We concentrated on the study of the Galactic flare, the increase of the sc
 ale-height with increasing Galactocentric distance. We will show prelimina
 ry results of our analysis, which shed some light on possibility of the fl
 aring of the Galactic disc in the remote regions of the Galaxy.\n\n\n
