A Solar System Survey of Forced Librations

Introduction: Physical librations in longitude are forced periodic variations of a body’s rotation rate. If the torque producing the librations can be calculated, then observations of the phase and amplitude of librations can provide information on mass distribution, and effective strength of the body. In the near future prospects for observing physical librations look quite promising. Radio in...

Flickering Events in Wind and Solar Power

This paper reports stochastic properties of renewable wind and solar energy resources by studying their conditional probability distribution functions (cpdf) in different time lags. The empirical results are obtained for data of global horizontal irradiance measured by a single sensor and the power output of a single wind turbine, as well as for an averaged solar sensor field and an aggregated ...

Modelling explosive events in the solar atmosphere

High–resolution ultraviolet (UV) spectra of the outer solar atmosphere show transient brightenings often referred to as explosive events. These are localized regions of small spatial extent that show sudden enhancements in the intensities of lines formed between 20,000 and 200,000 K, accompanied by strong non-gaussian profiles. The present work is an attempt to extract observational consequence...

Explosive events in the solar atmosphere

Two examples of explosive events observed with SUMER in transition region spectral lines are reported here; one detected in C iv 1548 Å, in a region within the northern polar coronal hole, and the other in O vi 1032 Å, in an active region. The event measured in C iv lasted ∼ 3 min and extended approximately a region of 8 arc sec along the slit (N-S) and 8 arc sec in the E-W direction. Velocitie...
