Title: Magnetic fields evolution during stellar formation at intermediate-mass stars

Presenter: Evelyne Alecian


Magnetic fields in main-sequence intermediate-mass stars are rare (less than 10%) and are most likely shaped during star formation. To better understand the origin of those fossile fields we aim at analysing the magnetic properties of the evolutionary precursor of those stars. I will present recent results on an ESPaDOnS survey of intermediate-mass T Tauri stars, as well as our current conclusions on magnetic field evolution during the pre-main-sequence phase. I will also discuss how SPIRou can help us to provide additionnal constraints on theories for the origin of magnetic fields in intermediate-mass stars.
