Context. In recent years the global seismic scaling relations for the frequency of maximum power, νmax ∝ g / √Teff, and for the large frequency separation, Δν ∝...
Non-local thermodynamic equilibrium inversions from a 3D magnetohydrodynamic chromospheric model
Context. The structure of the solar chromosphere is believed to be governed by magnetic fields, even in quiet-Sun regions that have a relatively weak...
Non-local thermodynamic equilibrium inversions of the Si I 10827 Å spectral line
Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic...
Non-LTE abundance corrections for late-type stars from 2000 Å to 3 µm. I. Na, Mg, and Al
Context. It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Making an accurate abundance determination requires...
Non-synchronous rotations in massive binary systems. HD 93343 revisited
Context. Most massive stars are in binary or multiple systems. Several massive stars have been detected as double-lined spectroscopic binaries and among these...
Non-transiting exoplanets as a means of understanding star–planet interactions in close-in systems
Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and...
Non-Vestoid candidate asteroids in the inner main belt
Context. Most howardite-eucrite-diogenite (HED) meteorites (analogues to V-type asteroids) are thought to originate from the asteroid (4) Vesta. However some...
Galaxy velocity mapsoften show the typical pattern of a rotating disk, consistent with the dynamical model where emitters rotate in circular orbits around the...
