April 24, 2002 | Using NASA's Rossi X-ray Timing Explorer satellite,
astronomers have found definitive proof that low-mass X-ray binary stars are
the precursors of millisecond pulsars. New observations of two X-ray binaries
provide convincing evidence that neutron stars are, indeed, whipped up to high
spin rates by mass transfer from a lower-mass companion star.
About 150 low-mass X-ray binaries (LMXBs) are known. In all cases, the X-rays
are due to gas from the companion sta
