“…The unique observational property of J1023 is millisecond optical pulsations, first found by [2] and confirmed in subsequent studies (e.g. [3][4][5]). The pulse profile has two peaks with variable amplitudes, reaching about 1 percent in the maximum.…”

We report some results of optical observations of the transitional millisecond pulsar PSR J1023+0038, performed with the multi-channel panoramic photometer-polarimeter mounted on the 6-meter BTA telescope. The setup allowed us to register photons simultaneously in two channels ("red" and "blue") with the effective temporal resolution of about 1 𝜇s. We detected optical pulsations at the pulsar frequency with characteristics similar to the ones reported in other studies. In addition, during one of the nights we observed dramatic change in the pulse profile structure, mainly characterized by fast transition from double-peaked to single-peaked shape and back, and accompanied by flaring activity of the system. We analyse the results and discuss some aspects of their physical interpretation regarding the origin of the pulsing emission.

“…Soon after, we succeeded in detecting them with Aqueye+@Copernicus, for the first time with a 2-m class telescope (Zampieri et al, 2019a). Other detections both in the optical (Karpov et al, 2019) and UV bands (Jaodand et al, 2021) were also reported since then.…”

Fast sub-second optical variability exists in some important classes of astrophysical sources, in particular pulsars and X-ray binaries. We regularly perform ultra-fast optical photometric campaigns on some of the most interesting targets and transient events. At the same time, we are tackling new campaigns searching for fast optical variability in other types of sources (Fast Radio Bursts, magnetars). To this end we use and develop dedicated fast photon counting instrumentation in the visible band, an area in which our team is the leader. Observations are carried out within the framework of multiwavelength campaigns and in synergy with facilities operating at other wavelengths.Here we report on some of the most recent observing campaigns and technological developments, and on the outcome of a km-baseline experiment of stellar intensity interferometry carried out in photon counting mode.

“…Quite surprisingly, also the optical emission observed from PSR J1023+0038 turned out to be pulsed with an rms amplitude of 1% [142,56,143,144]. This made PSR J1023+0038 the first optical MSP to date.…”

Millisecond pulsars in tight binaries have recently opened new challenges in our understanding of physical processes governing the evolution of binaries and the interaction between astrophysical plasma and electromagnetic fields. Transitional systems that showed changes from rotation-powered to accretion powered states and vice versa have bridged the populations of radio and accreting millisecond pulsars, eventually demonstrating the tight evolutionary link envisaged by the recycling scenario. A decade of discoveries and theoretical efforts have just grasped the complex phenomenology of transitional millisecond pulsars from the radio to the gamma-ray band. This review summarises the main properties of the three transitional millisecond pulsars discovered so far, as well as of candidates and related systems, discussing the various models proposed to cope with the multifaceted behaviour.
