Description
Nine type I post-main-sequence nebulae were observed in CO J = 2-1 using the NRAO 12-m antenna at Kitt Peak. It is found that, at the most, 20 percent of type I sources have antenna temperatures of greater than 0.2 K. The results suggest secondary kinematic splitting of the primary emission shell, and confirm the presence of high velocity outflows distinguished by an anomalous spatiokinematic morphology.

    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
