The present investigation is a continuation of earlier work by Hasan & Christensen-Dalsgaard (1992) and Banerjee, Hasan & Christensen-Dalsgaard (1995), who has examined the eeects of a weak vertical magnetic eld on the normal adiabatic modes of an isothermal atmosphere by combining a semi-analytic approach, based on asymp-totic dispersion relations, with numerical solutions. In the present stud...

Abstract Light bridges (LBs) are bright lanes that divide one sunspot umbra into two or more parts. Though frequently observed in sunspots, their formation mechanisms have rarely been studied and thus not well understood. Here we present results from the first statistical investigation on of LBs. Using observations with Helioseismic Magnetic Imager board Solar Dynamics Observatory, identified 1...

This paper discusses the strategies, considerations, and implications of designing performing with a light-dependent digital musical interface (DMI), named light.void~. is introduced as replica light thing, an existing DMI designed popularized by British artist Leafcutter John. The rationale for reproducing this presented, followed discussion around guiding criteria establishing data-to-sound m...

We used the Swarm-C accelerometer data to invert orbital atmospheric density in this study. First, satellite mission were obtained from ESA’s public platform, and preliminary error correction was performed. This paper refers calibration method of GRACE-A data. It adds linear temperature on original basis. Moreover, study’s results compared with published by ESA. In order explore influence light...

ABSTRACT A light bridge is a magnetic intrusion into sunspot, it interacts with the main field and excites variety of dynamical processes. In letter, we studied connectivity between coronal loops rooted at sunspot. We used data Atmospheric Imaging Assembly onboard Solar Dynamics Observatory(SDO) to study features sunspots bridges. It found that if anchors umbra-penumbra boundary, could not be f...
