Polarimetry towards star forming regions in our galaxy provides precious information on the physics of young stellar objects (YSOs) and their environment. Over the last few years, facilities like ALMA, VLA, VLT/SPHERE, Gemini/GPI, IRAM 30-m/NIKA2 have developed new capabilities that allow us to perform polarimetric measurements with increasing spatial resolution and sensitivity. These challenging and often time-consuming observations give us access to an otherwise inaccessible Universe: the intensity and morphology of magnetic fields and the properties of dust in protoplanetary disks.

This special session aims to:

• give an overview on the state-of-the art of the current instrumentation for polarimetry (optical to radio) and relative challenges
• discuss the different mechanisms generating polarised radiation as a function of evolution (embedded pre-stellar cores to debris disks) in young star forming regions in our galaxy
• present results from laboratory experiments on protoplanetary dust analogs and solar system samples
• bring together the communities working on polarimetric observations, laboratory measurements and theoretical predictions
• highlight the recent results and open issues in interpreting polarimetric observations, with a focus on magnetic fields and dust properties in young systems
• connect the results from the different areas of expertise and put them in the context of star formation, dust evolution and planet formation theories
