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 contribution from small scales in galaxy-galaxy lensing: comparison of mitigation schemes
Recent cosmological analyses with large-scale structure and weak lensing measurements, usually referred to as 3 × 2pt, had to discard a lot of signal to noise...
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 line profiles, rotation, and magnetic fields in seven DA white dwarfs
Non-LTE calculations of H-alpha line profiles are presented and applied to derive rotational velocities from high-resolution spectra of DA white dwarfs. This...
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-LTE Determination of the Silicon Abundance Using a Three-dimensional Hydrodynamical Model of the Solar Photosphere
Confrontations of spectroscopic observations with local thermodynamic equilibrium (LTE) spectral syntheses in a three-dimensional (3D) hydrodynamical model of...
In this paper we address the problem of the non-LTE (NLTE) inversion of line profiles by means of a nonlinear least-squares minimization procedure combined with...
Non-LTE Inversion of Stokes Profiles Induced by the Zeeman Effect
This paper presents a new diagnostic tool for the inference of the thermal, dynamic, and magnetic properties of the solar chromosphere. It consists of a non-LTE...
Non-LTE Inversions of the Mg II h & k and UV Triplet Lines
The Mg ii h & k lines are powerful diagnostics for studying the solar chromosphere. They have become particularly popular with the launch of the Interface...
