Nondetection of Helium in the Hot Jupiter WASP-48b
Hot Jupiters orbiting extremely close to their host star may experience atmospheric escape due to the large amounts of high-energy radiation they receive...
Nonequilibrium CO Chemistry in the Solar Atmosphere
Investigating the reliability of the assumption of instantaneous chemical equilibrium (ICE) for calculating the CO number density in the solar atmosphere is of...
Nonequilibrium ionization and ambipolar diffusion in solar magnetic flux emergence processes
Context. Magnetic flux emergence from the solar interior has been shown to be a key mechanism for unleashing a wide variety of phenomena. However, there are...
Nonextensive scalar field theories and dark energy models
Current astronomical measurements indicate that approximately 73% of the universe is made up of dark energy. Stochastically quantized self-interacting scalar...
Nonlinear flows along magnetic flux tubes - Mathematical structure and exact simple wave solutions
The mathematical structure of nonlinear, isentropic longitudinal flows of an ideal magnetohydrodynamic plasma confined to a magnetic flux tube embedded in a...
Nonlinear force-free modelling: influence of inaccuracies in the measured magnetic vector
Context. Solar magnetic fields are regularly extrapolated into the corona starting from photospheric magnetic measurements that can be affected by significant...
Nonlinear Instability of Kink Oscillations due to Shear Motions
First results from a high-resolution three-dimensional nonlinear numerical study of the kink oscillation are presented. We show in detail the development of a...
Nonlinear Numerical Simulations of Magneto-Acoustic Wave Propagation in Small-Scale Flux Tubes
We present results of nonlinear, two-dimensional, numerical simulations of magneto-acoustic wave propagation in the photosphere and chromosphere of small-scale...
Nonlinear time-evolution of kink-unstable magnetic flux tubes in the convective zone of the sun
The nonlinear development of the kink instability in a horizontal magnetic flux tube with a field strength exceeding the equipartition value lying initially in...
