Two sides of the same spin: tracking optical and radio pulsations of SAX J1808.4-3658 from outburst to quiescence

C. Ballocco, A. Miraval Zanon, A. Papitto +25

High-time-resolution optical and UV observations have revealed bright coherent pulsations from accreting millisecond pulsars, exceeding the luminosity expected from thermal emissio…

Assessing transitional pulsar candidates through a quantitative estimation of their light-curve similarity

D. F. Torres, C. R. García, F. Coti Zelati +5

Transitional millisecond pulsars are often identified through X-ray light-curve morphology, especially by visual comparison with the prototype PSR J1023+0038. Such classifications…

Searching for optical pulsations from spider millisecond pulsars with the fast photometer SiFAP2

Christian Malacaria, Alessandro Papitto, Filippo Ambrosino +19

Optical pulsations from millisecond pulsars (MSPs) have recently been detected in a transitional MSP and an accreting MSP. Evidence for optical pulsations has also been found for a…

Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1

Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17

Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…

Fast optical spectroscopic observations of PSR J1023+0038 over one orbital period

M. M. Messa, M. C. Baglio, P. D'Avanzo +8

Transitional millisecond pulsars (tMSPs) are neutron-star binaries that switch between rotation-powered and accretion-powered states, providing a key link between low-mass X-ray bi…

A FAST search for radio pulsations during the dormant state of the AMSPs IGR J00291+5934 and MAXI J1957+032

A. Marino, E. Parent, F. Coti Zelati +15

Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries which can evolve into "recycled" radio millisecond pulsa…
