Using mainly the 1600 angstrom continuum channel, and also the 1216 angstrom Lyman-alpha channel (which includes some UV continuum and C IV emission), aboard the TRACE satellite, we observed the compl...
The nonmagnetic interior of supergranulation cells has been thought since the 1940s to be heated by the dissipation of acoustic waves.But all attempts to measure the acoustic flux have failed to show ...

High frequency acoustic oscillations were suggested as the source of mechanical heating in the chromosphere. In this work the radial component of the oscillations in the frequency interval 3 mHz to ...
Brazilian Solar Spectroscope (BSS), operating in the frequency range of (1000 ¡ 2500) MHz with high time and frequency resolutions, has observed various fine structures showing intensity variati...
