Description
We present an analysis of time correlations between measurements of solar radius, neutrino flux data, and acoustic mode frequency shifts. We find significant anticorrelation of the first two quantities with the last one. Variations are found over time scales of order the 11 yr solar cycle and at shorter time scales. The shorter periods, of order 1 yr, are better detected during the period 1985-1991. These correlations strongly suggest the possibility that dynamical processes detected in upper solar layers are closely related with perturbations inside the sun, down to the core.

    Perspectives on the physics of late-type stars from beyond low earth orbit, the moon and mars
    With the new discoveries enabled thanks to the recent space missions, stellar physics is going through a revolution. However, these discoveries opened the door to many new questions that require more observations. The European Space Agency's Human and Robotic Exploration program provides an excellent opportunity to push forward the limits of our

    Echo-free quality factor of a multilayer axion haloscope
    We report a methodology to determine the quality factor ( Q) of wavy dark matter detectors equipped with multilayered resonators, including Fabry-Pérot interferometers and the so-called dielectric haloscope. An anechoic chamber enables the observation of the resonance frequency and its amplitude for an unlimited series of layers for the first time

    Magnetic diffusion in solar atmosphere produces measurable electric fields
    The efficient release of magnetic energy in astrophysical plasmas, such as during solar flares, can in principle be achieved through magnetic diffusion, at a rate determined by the associated electric field. However, attempts at measuring electric fields in the solar atmosphere are scarce, and none exist for sites where the magnetic energy is
