  Pad\'e approximants to truncated post-Newtonian neutron star models are
constructed. The Pad\'e models converge faster to the general relativistic (GR)
solution than the truncated post-Newtonian ones. The evolution of initial data
using the Pad\'e models approximates better the evolution of full GR initial
data than the truncated Taylor models. In the absence of full GR initial data
(e.g., for neutron star binaries or black hole binary systems), Pad\'e initial
data could be a better option than the straightforward truncated post-Newtonian
(Taylor) initial data.
