Our results show that main-sequence stars with no observable magnetic field  at the surface can still harbour strong fields in the core that survive  into the red giant phase.   The presence of internal magnetic fields might play an important role for  angular momentum transport.   [AND potentially influence mixing processes in their interiors REF TO WHAT  REF-2 TALKS ABOUT]  Fields too weak to suppress dipolar oscillation modes may exist in normal  red giants, and these fields may nevertheless transport enough angular  momentum to help explain the measured rotation rates of red giant cores  \citep{Mosser_2012,Cantiello_2014}.   After some time, intermediate-mass red giants also start burning helium in  their cores. Suppressed dipolar modes in those so-called red clump stars  will reveal whether the fields survive until helium-core burning, and  whether they can account for magnetic fields observed in stellar remnants  such as white dwarfs. Like intermediate-mass stars, more massive stars  ($M>10$\msun) also undergo convective hydrogen-core burning that generates  a magnetic dynamo, and which may produce the magnetic fields observed in  many neutron stars.
