Description
A Michelson interferometer has been built for use with the 91-cm telescope on NASA's Gerard P. Kuiper Airborne Observatory primarily to measure IR line emission from H II regions. Operation is in the rapid scan mode, and the achievable resolution is 0.02/cm in the wavelength range from 10 to around 300 microns. A minicomputer is used to provide on-line spectrum displays and to control and monitor the instrument performance. The design and use of the instrument is discussed, and a comparison is made between the theoretical performance and that actually achieved on the first flights when measurements of line emission from the Orion nebula and from the atmosphere were made.

    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
