    X-ray and optical observations of the millisecond pulsar binary PSR J1431–4715
    We present the first X-ray observation of the energetic millisecond pulsar binary PSR J1431‑4715, performed with XMM-Newton and complemented with fast optical...

    X-Ray States of Redback Millisecond Pulsars
    Compact binary millisecond pulsars with main-sequence donors, often referred to as "redbacks," constitute the long-sought link between low-mass X-ray binaries...

    XTE J1751-305 going back to its quiescent state
    After the recent reports of activity of the accreting millisecond pulsar XTE J1751-305 (ATELs #1045, #1046 and #1051) we obtained another Swift/XRT (~4.3ksec)...

    XTE J1855-026 is a supergiant X-ray binary
    The eclipsing X-ray pulsar XTE J1855-026 (Corbet & Mukai 2002, ApJ 577, 923) has been unambiguously identified by a recent Swift observation (Romano et al...
