Investigating the role of magnetic fields in the formation of stars and planetary systems:
the MAPP project

MAPP (MAgnetic Protostars and Planets) is a new project aimed at investigating the role of magnetic fields in the formation of stars and planetary systems. Youth is indeed the period in the life of stars where magnetic fields are expected to have the strongest impact, eg through the magnetically-controlled accretion/ejection processes involved in the collapse of the protostellar cloud from which stars and planets form.

MAPP focusses especially on the core regions of protostellar accretion discs - including the newly born star and closely orbiting planets. By collecting new observational data and running dedicated multi-D MHD numerical simulations, MAPP is expected to unveil how magnetic fields modify the formation of stars and their protoplanetary systems.

The MAPP core team spreads between LATT (Toulouse), ENS (Lyon & Paris), LAOG (Grenoble), IAP (Paris) and CEA (Saclay); collaborators from Europe, North-America and Asia are also expected to participate in the project. MAPP is funded by the French "Agence Nationale de la Recherche" (ANR) and supported by the French national program on Stellar physics (PNPS).

MAPP is part of the MagIcS international initiative aimed at studying the origin and impact of magnetic fields on stars throughout the HR diagram.
