With the increasing size of the ground based telescopes, the lines used to carry and distribute cryogenic gas or fluid to instruments need continuously to be longer. Cryogenic transfer lines of a few 10 meters will be common in future infrastructures. Transfer cryogenic fluid requires highly insulated lines in order to minimise the coolant

The magnetic field is the main driver of the activity in the solar upper atmosphere, but its measurement is notoriously difficult. In order to determine the magnetic field in the chromosphere, transition region, and corona, we need to measure and interpret the polarization signals that the scattering of anisotropic radiation and the Hanle and

Context. Comparing the properties of planets orbiting the same host star, and thus formed from the same accretion disc, helps in constraining theories of exoplanet formation and evolution. As a result, the scientific interest in multi-planetary systems is growing with the increasing number of detections of planetary companions. Aims: We report the

We present JWST/MIRI MRS spectroscopy of NGC 7319, the largest galaxy in the Stephan's Quintet, observed as part of the Early Release Observations (ERO). NGC 7319 hosts a type 2 active galactic nucleus (AGN) and a low-power radio jet (L 1.4 GHz = 3.3 × 10 22 W Hz −1) with two asymmetric radio hotspots at 430 pc (N2) and 1.5 kpc (S2) projected

Context. It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Making an accurate abundance determination requires taking those effects into account, but the necessary non-LTE (hereafter NLTE) calculations are often lacking. Aims: Our goal is to provide detailed estimates of NLTE effects for FGK type stars
