Scientific paper

It is argued that the low-mass companion of PSR1829 - 10 began its life as a star and has been ablated down to its present mass by absorbing a portion of the pulsar's spindown energy. Similar phenomena have already been seen in two other binary pulsars, PSR1957 + 20 and PSR1744 + 24A. The final mass of the remnant is determined by the interplay between decreasing spindown luminosity, recession of the companion from the pulsar as a result of its mass loss, and most important, shrinkage of the companion due to convective cooling of its interior.
