Accelerated Orbital Expansion and Secular Spin-down of the Accreting Millisecond Pulsar Sax J1808.4−3658

Accelerated Orbital Expansion and Secular Spin-down of the Accreting Millisecond Pulsar Sax J1808.4−3658

The accreting millisecond pulsar SAX J1808.4-3658 has shown a peculiar orbital evolution in the past with an orbital expansion much faster than expected from standard binary evolutionary scenarios. Previous limits on the pulsar spin frequency derivative during transient accretion outbursts were smal...
