Interactions between reversed granulation , p - modes , and magnetism ? Alfred

چکیده
We investigate features that are observed in Ca ii H sequences from Hinode in places where reversed granulation seems to interact with pmodes. These features appear ubiquitously in the quiet sun. They are cospatial with reversed granulation, and display similar general properties, but have sharper edges and show fast brightness changes. They also appear predominantly above wide intergranular lanes, indicating a potential connection with magnetism. We report on the appearance and dynamics of these features using high-resolution, high-cadence observations from Hinode, and we discuss their possible origin.

The role of the f-mode in the relation between solar intensity oscillations and granulation
A series of white-light images is used to examine the relation of solar intensity oscillations and the granulation structure. Much of the oscillation power lies on the f-mode ridge in the diagnostic diagram. Filters are constructed to separate granulation, p-modes, and the f-mode. The filtered data are used to investigate the relation between rms-amplitudes of the oscillations and the granulati...
متن کاملComparison of the Effects of Different Negative Pressure Wound Therapy Modes—Continuous, Noncontinuous, and With Instillation—on Porcine Excisional Wounds
OBJECTIVE Negative pressure wound therapy (NPWT) can be delivered in continuous or noncontinuous modes, while NPWT with instillation (NPWTi) couples NPWT with automated delivery and removal of topical wound treatment solutions and suspensions. This porcine study compared granulation response of NPWTi (instillation foam dressing with saline) to NPWT (standard foam dressing) in continuous and non...
متن کاملمثالی از پیچیدگی در مغناطیس: ساختارهای پیچیده مغناطیسی در میان فلزات نادر خاکی
We present and compare the magnetic structures of limit compounds, between the ferromagnetism and antiferromagnetism in the pseudobinary compounds of type RNi/Pt/Cu, where R = Tb, Gd, Nd or Ce, appearing when we substitute the transition metal. All of them are examples of complex magnetic structures as the result of different magnetic interactions, inhomogeneities and disorder. This overview p...
متن کاملVariations of the solar granulation motions with height using the GOLF / SoHO experiment
Context. Below 1 mHz, the power spectrum of helioseismic velocity measurements is dominated by the spectrum of convective motions (granulation and supergranulation) making it difficult to detect the low-order acoustic modes and the gravity modes. Aims. We want to better understand the behavior of solar granulation as a function of the observing height in the solar atmosphere and with magnetic a...
متن کاملEffects of granulation on the visibility of solar oscillations
Context. The interaction of solar oscillations with near surface convection is poorly understood. These interactions are likely the cause of several problems in helioand astero-seismology, including the so-called surface effect and apparently unphysical travel time shifts as a function of center to limb distance. There is thus a clear need for further theoretical understanding and observational...
