DESCRIPTION:Dynamical studies suggest that most of the circumbinary discs s
 hould be coplanar\, i.e. the rotation vectors of the binary and the disc a
 re aligned. However\, some recent theoretical works show that under certai
 n conditions a circumbinary disc can become polar\, which means that its r
 otation vector is orthogonal with respect to the binary.\nWe study the evo
 lution of misaligned circumbinary discs and the dynamical evolution of the
 ir potential polar planets. Furthermore\, we produce dynamical maps for di
 fferent binary parameters and identify the combination of parameters that 
 lead to disc polar alignment. Finally\, we numerically test recent theoret
 ical predictions based on linear theory.\nWe found out that polar and retr
 ograde circumbinary discs are an expected outcome around misaligned binary
  systems. In such systems\, the resulting planetary architectures could be
  polar and retrograde as well. We show that polar planet configurations ar
 e stable over a wide range of binary parameters. Therefore\, despite their
  low probability of detection\, we suggest that polar (P-type) planets mig
 ht be more common than previously thought. https://astronomia.uc.cl/2jucex
