DESCRIPTION:Recently\, protoplanetary disc kinematics has gained significa
 nt interest\, as it directly traces the disc structure\, unveils planet-di
 sc interactions\, and tests the presence of hydrodynamical instabilities. 
 exoALMA\, an ALMA Large Program\, is dedicated to characterizing the kinem
 atics of planet-forming environments with unprecedented precision. In this
  talk\, I will present the work carried out by the exoALMA collaboration\,
  focusing on modelling rotation curves to constrain dynamical masses of st
 ars and discs. Rotation curves have long been used in galactic astronomy t
 o infer the presence of dark matter. In protoplanetary discs\, thanks to t
 he high spatial and spectral resolution of ALMA\, they provide a powerful 
 tool to probe the dynamical mass\, revealing key properties of both the ce
 ntral star and the surrounding disc.
