Can we establish a coherent picture of the role of the magnetic field in the star-formation sequence\u00a0across time and spatial scale, in spite of the diverse observational techniques and analysis tools\u00a0used to observe magnetic fields in molecular clouds, cores, protostars, disks and young stars\u00a0arriving on the main sequence?<\/p>\n

While it is believed that magnetic fields play important roles in star formation processes, in particular\u00a0to overcome both the angular momentum and magnetic flux problems, polarimetry from the optical to the\u00a0centimeter wavelengths has been so far the most powerful observing technique to study them. This Focus\u00a0Meeting aims at triggering a synergetic reflection on how to compare, combine, and synthesize\u00a0observational and theoretical knowledge of the end-to-end role of the magnetic fields in the\u00a0formation of stars. We hope to sample the landscape of state-of-the-art observations and models of\u00a0magnetic fields at the various stages and scales of the star-formation process, from molecular clouds\u00a0to young stars reaching the ZAMS.<\/p>\n

In this Focus Meeting we wish to gather the different communities working with magnetized models and\u00a0polarimetric observations of the various stages and objects along the star formation sequence. The\u00a0goal is to discuss how to compare constraints on magnetic fields at different evolutionary stages and physical scales such that we can establish a coherent view of their key role in the multi-scale process\u00a0of star formation. Combining observational results and theoretical expectations coming from diverse\u00a0techniques used in different communities is complex, so we especially welcome contributions that will emphasize how different measurements of the magnetic fields can be compared and interpreted into a\u00a0coherent picture despite widely varying observing techniques, and the very different objects and\u00a0physical scales that are involved all along the star formation sequence.<\/p>\n

The Focus meeting will stretch over two days at the end of the 30th IAU General Assembly in Vienna, on August 30-31 2018. We expect to be able to accommodate about 20 talks and unlimited number of posters.<\/p>\n
