As this binary has a spectral classification of G4V I suggest the dip in the light curve is due to chromospheric
Such a model can account for the presence of both He I and He II emission lines in the chromospheric
On Aug 8 a spectacular 'horned' dark filament graced the SE quadrant which was still present the following day, matching the alignment of chromospheric
disturbance in the SW quadrant.
They cover interior, convection, and dynamo, the formation and evolution of sunspots and active regions; flux emergence and submergence; waves, reconnection, and chromospheric
and coronal heating; magnetic fields as structuring agents of the solar atmosphere; flares, eruptions, and particle acceleration; solar wind and the interplanetary space; and Hinode and Solar Dynamics Observatory.
6 arcsec pixels, in temperatures ranging from chromospheric
around 10,000 K up to about 10 million K, with images every 12 seconds, without interruption.
Starting at roughly 6,000 kelvins at the sun's surface, the solar atmosphere's temperature falls to nearly 4,300 kelvins at an altitude of 500 kilometers before rising to typical chromospheric
As the chromospheric
ribbon swept across the region signaling the reconnection of the field lines that were opened during the eruption, the same cells reappeared immediately behind the ribbon.
we assumed that the distribution in the continuous chromospheric
spectrum is the same as that of a black body at 5700[degrees], and that the continuous spectrum from the extreme edge is that of a black body at 4700[degrees].
In any event, chromospheric
heating, from turbulent motion, wave motion, magnetic fields, or 5-minute oscillations , is not required to support the great spatial extent of the chromosphere in the LMH model.
6 mag in the V band and interpreted as the rotationally modulated effect of cool spots on their surfaces, a result of increased chromospheric
Among the topics are gravitational wave foreground radiation from neutron star-dwarf binaries, the chromospheric
activity of late-type stars of the different rotational periods, spectrophotometry and model atmosphere flux fitting, the light-time effect and tertiary companions in close binary stars, the age of the local interstellar bubble, and the current status and outreach activities of radio astronomy in Malaysia.
In introducing 54 papers that presented a sample of its first results and related theoretical models at the 2007 ASP conference, Matthews (UCL Mullard Space Science Laboratory, Surrey, UK) and coauthors from NASA and the National Astronomical Observatory of Japan explain Hinode's mission to provide information on how solar magnetic fields are formed, evolve, and interact with plasmas to create the photospheric and chromospheric
