             abstract = "Recently, a braking index for the pulsar PSR J1640-4631 has been 
                         measured. With a braking index of n = 3.15 +/- 0.03, this pulsar 
                         has the highest braking index ever measured. As it is well known, 
                         a pure magnetic dipole brake yields n = 3, whereas a pure 
                         gravitational wave (GW) brake yields n = 5. Therefore, each of 
                         these mechanisms alone can not account for the braking index found 
                         for PSR J1640-4631. Here we consider in detail that such a braking 
                         index could be accounted for if the spindown model combines 
                         magnetic dipole and GW brakes. Then, we briefly discuss the 
                         detectability of this pulsar by aLIGO and the planned Einstein 
                         Telescope. In particular, we show that the amplitude of the GW 
                         that comes from our model is around a factor four lower than the 
                         amplitude modeled exclusively by GW energy loss. Another 
                         interesting outcome of our modeling is that it is possible to 
                         obtain the ellipticity from the braking index and other pulsar
