A physical limit to the magnetic fields of T Tauri stars.
SAFIER P.N.
Abstract (from CDS):
Recent estimates of magnetic field strengths in T Tauri stars yield values of B=1-4 kG. In this Letter, I present an upper limit to the photospheric values of B by computing the equipartition values for different surface gravities and effective temperatures. The values of B derived from the observations exceed this limit, and I examine the possible causes for this discrepancy.
