NOEMA redshift measurements of bright Herschel galaxies
Using the IRAM NOrthern Extended Millimeter Array (NOEMA), we conducted a program to measure redshifts for 13 bright galaxies detected in the Herschel...
Noise properties of the CoRoT data. A planet-finding perspective
In this short paper, we study the photometric precision of stellar light curves obtained by the CoRoT satellite in its planet-finding channel, with a particular...
Noise reduction in helioseismic power spectra by non-orthogonal wavelets
We present a method to reduce noise in helioseismic power spectra using a non-orthogonal wavelet transform based on quadratic spline functions. The quality of...
Non-grey dimming events of KIC 8462852 from GTC spectrophotometry
We report ground-based spectrophotometry of KIC 8462852 obtained during its first dimming events since the end of the Kepler mission. The dimmings show a clear...
Non-linear radial pulsation models for the early-type helium stars V652 Her and BX Cir
We report new non-linear pulsation models of the helium stars V652 Her and BX Cir. Linear theory has previously shown their pulsations to be due to iron-group...
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-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...
