We quantify the
mass-dependent mode suppression mass-dependence in Fig. 3 by
showing the relative number of
stars with suppressed
dipole modes stars (those below the dashed
line in Fig. 2) in narrow mass intervals.
We see no
stars with reduced power suppression in
the dipole modes stars below
1.1\msun, while above this threshold there
is first a gradual increase followed by a rapid increase above approximately
1.5\msun, and a drop beyond 2.0\msun.
The onset of suppression beyond 1.1\msun, 1.1\msun.
This coincides with the mass
above below
which stars
are thought to do not form convective cores during their hydrogen-core burning phase \citep{Kippenhahn_1990}.
We believe The onset of magnetic suppression above this
shows evidence for threshold suggests the
establishment existence of
convectively driven dynamos in the cores of
at least some hydrogen-core burning
stars that are only 10-20\% more massive than the Sun
\citep{Charbonneau_2001,MacGregor_2003,Brun_2005}. (main-sequence)
stars. This agrees well with theoretical predictions based on 3D hydrodynamical modeling
\citep{Brun_2005}.
%[THE SENTENCE BEFORE AND AFTER DONT REALLY WORK TOGTHER BUT I FEEL WE NEED TO SAY SOMEHOW WHAT IS SAID IN THE FOLLOWING SENTENCE]
The resulting strong magnetic fields must survive long after the dynamo terminates at the end of hydrogen-core burning in order to be detected during the red giant
phase. phase; [REPHRASE REST OF SENTENCE OR REMOVE] a results that was not certain from the 3D hydrodynamical simulations.
% The gradual increase in suppression may result from the increasing size of

Stars above $1.6 M_\odot$ show a 50-60\% suppression rate, much larger than
can be accounted for by the up to 10\% of A-type stars known to show strong surface fields,
\citep{2008CoSka..38..443P}. This shows
