摘要：
We study the spin-down of a neutron star atmosphere during the type I X-ray burst in low mass X-ray binaries. Using polar cap acceleration models, we show that the resulting stellar "wind" torque on the burning shell due to the flowing charged particles ( electrons, protons and ions) from the star's polar caps may change the shell's angular momentum during the burst. We conclude that the net change in the angular momentum of the star's atmosphere can account for rather large frequency drifts observed during type I X-ray burst.
