Mapa del Sitio . Corona solar . ... 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. ...

R Coronae Borealis (RCB) stars are hydrogen-deficient, carbon-rich, pulsating, post-asymptotic giant branch stars that experience massive irregular declines in brightness caused by circumstellar dust formation. The mechanism of dust formation around RCB stars is not well understood. ... Effective temperatures of the eight RCB stars range from 4000 to 7250 K. The observed photospheric CO absorption bands were compared to line-blanketed model spectra of RCB stars. ... ADS Citation Query . ...
