Description

A stellar photometer is in preparation as a joint project of the University of Rome and the Astrophysical Observatory of Catania. It is based on a suitable version of the Magneto-Optical Filter (MOF). The aim is to detect magnetic and velocity signals on stars. The basic idea is shown in the figure. The photometer is able to maximize the collection of photons. As far as the magnetic field measurement is concerned we consider only the transverse component of the magnetic field that should provide detectable U and Q Stokes parameter (linear polarization). Tests on the sun are part of this program
