Description
Position data of sunspot groups from the period 1874-1902 are used to investigate the differential rotation of the Sun and the meridional motions of the sunspots. The equatorial velocity is higher than in the period 1940-1968 investigated by Balthasar and Wöhl (1980), while differences between the northern and southern hemispheres are less. For cycle 12 we find meridional motions towards north while in cycle 13 the motions are directed towards south like in the period 1940-1968. Our other results are comparable to those of Balthasar and Wöhl (1980) for the period 1940-1968.

    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
