Query: Radio pulsar and accretion regimes of rapidly rotating magnetic neutron
  stars in early-type eccentric binaries   Rapidly rotating magnetic neutron stars in eccentric binary systems
containing an early type star provide a unique opportunity to investigate the
interplay between radio pulsar, stellar wind and accretion phenomena. We
summarise the radio pulsar-dominated and the accretion-dominated regimes,
discussing how the transition from one regime to another can take place as a
result of the varying orbital distance and relative velocity along the orbit,
as well as changes of the wind characteristics. We derive the conditions under
which the two known B star/radio pulsar binaries (PSR 1259-63 and PSR
J0045-7319) can undergo a transition to the accreting regime. A strong increase
of the mass loss ouflow from the companion is required, just to cause the onset
of accretion onto the magnetospheric boundary. We also show that the X--ray
transient A0538-66 is likely to undergo transitions from the accreting neutron
star regime, to the regime of accretion onto the magnetosphere. These two
regimes might correspond to the high (> 10^{38} erg/s) and the low-luminosity
(< 10^{38} erg/s) outbursts observed from this source. A radio pulsar might
become detectable in the long quiescent states of A0538-66. A new model of the
enigmatic high-energy binary LS I +61 303 involving accretion onto the
magnetosphere is also presented.
