Solar activity cycle frequency shifts of low-degree p-modes

We report on an extensive analysis of the low-degree p-mode frequency shifts over Solar Cycle n ̄ 22 (1984–1995) based on continuous data taken at the Observatorio del Teide (Tenerife). Aside from the known good correlation between frequency shifts and solar activity indices, we have also investigated on short and long time-scales correlations (from 2months to 1.5 years and from 1.5 to 11 years)...

EXCITATION OF SOLAR p-MODES

We investigate the rates at which energy is supplied to individual p-modes as a function of their frequencies v and angular degrees t. The observationally determined rates are compared with those calculated on the hypothesis that the modes are stochastically excited by turbulent convection. The observationally determined excitation rate is assumed to be equal to the product of the mode's energy...

Peak bagging for peptide mass fingerprinting

MOTIVATION Mass Spectrometry (MS)-based protein identification via peptide mass fingerprinting (PMF) is a key component in high-throughput proteome research. While PMF was the first commonly used protein identification method, provided higher throughput than the tandem MS-based method, its accuracy is lower than that of the tandem MS method. Thus, it is desirable to develop PMF-based algorithm ...

A framework for describing correlated excitation of solar p modes

In a previous paper we suggested that, for a given p mode, the excitation function is the same as the component of the solar background noise that has an identical surface spherical harmonic projection (over the corresponding range of temporal frequency). An important consequence of this surmise is that the excitation of overtones of a given angular degree and azimuthal order will be correlated...

Absorption / Emission of Solar P - modes : MDI

We search for sources and sinks of solar p-mode waves by creating absorption maps from Dopplergrams taken by the Michelson Doppler Interferometer (MDI) instrument on board SOHO. Although the maps are noisy, we present evidence for sources and sinks, of duration 0.5 { 1 hour or less, based on an autocorrelation analysis of maps made from sequential intervals of data. Emission and absorption near...
