Research into the Magnetic Configuration of Eruptive Filaments with a High-class Flare
The Astrophysical JournalFilament eruptions are the source of coronal mass ejections, and these phenomena are likely to pose a serious threat to space weather safety. The magnetic structures that carry the filament material are considered the core structures of the eruption, and

Quasiperiodic Slow-propagating Extreme-ultraviolet “Wave” Trains after the Filament Eruption
The Astrophysical Journal LettersThe eruption of the filament/flux rope generates the coronal perturbations, which further form extreme-ultraviolet (EUV) waves. There are two types of EUV waves, namely, fast-mode magnetosonic waves and slow waves.

Boreas, EarlyView.The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Initiation Route of Coronal Mass Ejections. II. The Role of Filament Mass
The Astrophysical JournalA thorough understanding of the initiation of coronal mass ejections (CMEs), which is manifested as a slow rise of pre-eruptive structures before the impulsive ejection in kinematics, is key for forecasting solar eruptions.

Solar filaments: characteristics and evolution
, 2011 Este trabalho tem como principal objectivo o estudo dos flamentos solares, começando com um estudo estatístico que levou à criação e implementação de um modelo computacional. Os estudos estatísticos realizados estão relacionados com a longitude e latitude de Carrington, com o comprimento, a curvatura e a orientação dos filamentos.

International Journal of Cosmetic Science, EarlyView.UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

The Structures, Mass Motions And Footpoints Of Solar Filaments
, 2014 This thesis focuses on identifying the mechanism by which solar filaments acquire mass. Some of the speculations for how a filament gets its mass are 1) injection of mass from the chromosphere into the filament structure, and 2) condensation of mass from

Meteoritics &Planetary Science, EarlyView.Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...
