Description
The identification of the optical companions to binary millisecond pulsars
(MSPs) is fundamental to characterize the formation and evolutionary
processes of these exotic objects and to constrain the neutron star mass.
In Globular Clusters (GCs) it also represents a crucial tool for quantifying
the occurrence of dynamical interactions and understanding the effects of
high stellar densities on the evolution of binaries.
In this context I will present the main results recently obtained with the use of
HST images that allowed us to succesfully increase the number of identified
companions to MSPs in GCs. In particular, I will focus my attention to the
optical companion to the transient IGR J18245-2452/PSR J1824-2452I in the GC
M28.
