Analysis of Umbral Dots (5)<br />
Conclusions:<br />
Riethmüller et al., 2008<br />
�� inversion results are<br />
remarkably similar to<br />
simulations of Schüssler &<br />
Vögler (2006)<br />
� UDs differ from their surrounding<br />
mainly y in lower layers y<br />
� T higher by ~ 550 K<br />
� B lower by ~ 500 G<br />
�� upflow ~ 800 m/s<br />
� differences to V&S:<br />
� field strength g of DB is found to be<br />
depth dependent<br />
� surrounding downflows are<br />
present, but not as strong and as<br />
narrow as in MHD (resolution?)<br />
