Explicit Periodic Solutions in a Delay Differential Equation
Anatoli Ivanov, Sergiy Shelyag
We construct stable periodic solutions for a simple form nonlinear delay differential equation (DDE) with a periodic coefficient. The equation involves one underlying nonlinearity…
Modelling host population support for combat adversaries
Mathew Zuparic, Sergiy Shelyag, Maia Angelova +2
We consider a model of adversarial dynamics consisting of three populations, labelled Blue, Green and Red, which evolve under a system of first order nonlinear differential equatio…
The Dynamics of Rapid Redshifted and Blueshifted Excursions in the Solar Halpha line
D. Kuridze, V. Henriques, M. Mathioudakis +5
We analyse high temporal and spatial resolution time-series of spectral scans of the Halpha line obtained with the CRisp Imaging SpectroPolarimeter (CRISP) instrument mounted on th…
Spectro-polarimetric simulations of the solar limb: absorption-emission FeI and line profiles and torsional flows in the intergranular magnetic flux concentrations
S. Shelyag
Using radiative magneto-hydrodynamic simulations of the magnetised solar photosphere and detailed spectro-polarimetric diagnostics with the FeI and $6302.5\mathrmÅ…
Understanding Astrophysical Noise from Stellar Surface Magneto-Convection
H. M. Cegla, C. A. Watson, S. Shelyag +1
To obtain cm/s precision, stellar surface magneto-convection must be disentangled from observed radial velocities (RVs). In order to understand and remove the convective signature,…
Vortices in the solar photosphere
S. Shelyag, V. Fedun, R. Erdélyi +2
Using numerical simulations of the magnetised solar photosphere and radiative diagnostics of the simulated photospheric models, we further analyse the physical nature of magnetic p…
