Stellar Wind and the Efficiency of Plasma Radio Emission from Exoplanets
AbstractWe present the results of our study of the influence of stellar activity on the efficiency of the plasma radio emission generation mechanism...

Interaction of the Exoplanet Hat–P–11b with Stellar Wind
AbstractWe discuss possible existence of a magnetodisk around the exoplanet HAT–P–11b. We used available observations to determine properties of the...

Kinetic Model of the Effect of the Stellar Wind on the Extended Hydrogen Atmosphere of the Exoplanet π Men c
AbstractIn this work, the kinetic model of aeronomy of the upper atmosphere of an exoplanet is extended by including the effect of stellar wind...

Transition from Super-Alfvénic to Sub-Alfvénic Stellar Wind Flow Passing by an Exoplanet, Using the Example of HD 209458b
AbstractDepending on the distance of the exoplanet from the central star and the properties of this star, different regimes of stellar wind flow...

Magnetic Barrier in Front of Exoplanets Interacting with Stellar Wind
The interaction between the magnetized stellar wind plasma and the hydrodynamic flow from the upper atmosphere of a non-magnetic exoplanet is...

Interaction of the Supersonic Stellar Wind with Free Stream of the Interstellar Medium: the Effect of the Azimuthal Magnetic Field of the Star
AbstractThe problem of the interaction of a hypersonic stellar wind with the surrounding interstellar medium is considered. The media are assumed to...

Evolution of the X-ray Binary System Sco X-1 within the Framework of the Induced Stellar Wind Model
AbstractWithin the framework of the induced stellar wind (ISW) model, the possible evolution of the X-ray binary system Sco X-1 after the formation...
-
Stellar Dynamos
In the previous chapter we discussed the various aspects of stellar activity. In this chapter we will outline the underlying theoretical background...
-
Stellar Rotation and Stellar Activity
Stellar rotation is an important factor that also determines stellar activity. This was explained in the previous section when an overview of stellar...
-
Stellar Magnetic Fields
Stellar magnetic fields are directly detected or inferred across the whole Hertzsprung--Russell Diagram. Attention in this chapter is concentrated on...
-
Ultraviolet spectropolarimetry: investigating stellar magnetic field diagnostics
Magnetic fields are important for stellar photospheres and magnetospheres, influencing photospheric physics and sculpting stellar winds. Observations...

Scaling and Evolution of Stellar Magnetic Activity
Magnetic activity is a ubiquitous feature of stars with convective outer layers, with implications from stellar evolution to planetary atmospheres....
-
An abrupt change in the stellar spin-down law at the fully convective boundary
Unlike partially convective stars such as the Sun, fully convective stars do not possess a radiative core. Whether a star needs this core to generate...

Magnetically Confined Wind Shock
Many stars across all classes possess strong enough magnetic fields to influence dynamical flow of material off the stellar surface. For the case of...

Interaction between Internal Shocks and the Reverse Shock for a GRB in a Dense Stellar Wind
In the most popular scenario for GRBs a relativistic shell is produced by a compact central source (collapsar, BH + WD, BH + NS or NS + NS merger)...
-
Computational methods for collisional stellar systems
Dense star clusters are spectacular self-gravitating stellar systems in our Galaxy and across the Universe—in many respects. They populate disks and...
-
Stellar Coronae
The vast majority of “normal” hydrogen-burning stars are of mass equal to or lower than that of our Sun, and they share with our host star the...
-
Stellar Rotation Along the HR-Diagram
The HR-diagram (Hertzsprung-Russell diagram, HR-diagram) has already been discussed in the introductory chapter. It is a plot of stellar temperatures...

Science with a Small Two-Band UV-Photometry Mission II: Observations of Stars and Stellar Systems
We outline the impact of a small two-band UV-photometry satellite mission on the field of stellar physics, magnetospheres of stars, binaries, stellar...

Optical Characteristics of a Magnetocentrifugal Disk Wind in the Visual, Ultraviolet, and X-ray Spectral Ranges
AbstractThe optical characteristics of a magnetocentrifugal disk wind from T Tauri stars that we calculated based on the MHD models of Safier (1993a,...
