Description
The identification of two new southern planetary nebulae, IRAS 16455-3455 and IRAS 15154-5258, via low resolution spectroscopy, is reported. IRAS 16455-3455 is a high excitation planetary nebula with an extension of 9 arcsec, m(V) = 8.95 and E(B-V) = 1.21. Chemical abundances in this nebula are similar to the mean values for planetaries in the Galaxy. IRAS 15154-5258 is a hydrogen-poor nebula with a high infrared excess. The central star has a WC4 Wolf-Rayet spectrum.

    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

    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

    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
