Be/X-ray Pulsars in Quiescence

We propose to observe several transient Be/Xray binary pulsars in quiescence.While these sources have been extensively studied during outbursts, little isknow about their behaviour at low luminosities.There is a disctinct chance to observe centrifugal inhibition of accretion thesocalled propellereffect. If this is not observed, significant insight can begained into the accretion and emission geometry by comparing these results withthose obained while the sources were much brighter. The sources we propose toobserve are A0535+262, V0332+53 and A053866. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
