Las estructuras visibles en la corona en esos momentos sugieren que est n configuradas por campos magn ticos y, por lo tanto, que la corona est constituida por plasma. Por ejemplo, los cortos "penachos" que se elevan desde las regiones polares del Sol tienen la apariencia de la l neas de campo saliendo de una barra imantada, que sugieren que el Sol tiene, adem s de los intensos campos de las manchas, un campo magn tico global como el de la Tierra. ...

The Sun's corona . ... For instance, short "plumes" rising from the polar regions of the Sun look very much like field lines coming out of the end of a bar magnet, and they therefore suggest that the Sun, in addition to the intense fields of sunspots, also has a global magnetic field like the Earth's. Arches above the . Sun's surface . ... It is brightest near sunspots, whose arched field lines apparently hamper the outflow of solar wind which carries away energy and helps cool the corona. ...

In 2007, R Coronae Borealis (R CrB) went into a historically deep and long decline. ... The evidence pointing toward a white dwarf merger or a final-helium-shell flash origin for R CrB is contradictory. ... Along with the fact that R CrB shows significant lithium in its atmosphere, this supports the final-helium-shell flash. However, the relatively high inferred mass of R CrB and its high fluorine abundance support a white dwarf merger. ...

... Empirical and theoretical modeling of 3-D structures in the solar corona is confronted by the tremendous amount of data needed to represent phenomena with a large dynamic range both in size and magnitude, and with a rapid temporal evolution. Octree representation of the 3-D coronal electron distribution offers the right compromise between resolution and size, allowing computation of synthetic images of the solar corona. ... The time interval between images is one day. ...
