The characteristics of the astrospheres of convective dwarf stars, such as their radii, mass loss rates, and steady-state outflow rates, are shown by dimensional considerations to be related by simple analytic formulas to the basic parameters of the stars, their mass, radius, and rotation velocity.

On the 3D transport of galactic cosmic rays in a selection of exoplanet-hosting astrospheres: the influence of stellar rotation [PDF]
Monthly Notices of the Royal Astronomical SocietyGalactic cosmic rays (GCRs) may influence the habitability of exoplanets. The recently proposed relationship between GCR intensities at exoplanetary locations and the rotation periods of their host stars is here investigated for several M-dwarf ...

The heliospheric hydrogen wall and astrospheres
Advances in Space Research, 2004Abstract Charge exchange processes in the outer heliosphere produce a population of hot hydrogen gas within the heliosphere, creating a “hydrogen wall” between the heliopause and bow shock. The heliospheric hydrogen wall scatters Lyα photons passing through it, producing a detectable absorption signature in observations of H I Lyα emission from ...

Habitable Zones Exposed: Astrosphere Collapse Frequency as a Function of Stellar Mass
Astrobiology, 2009Stellar astrospheres--the plasma cocoons carved out of the interstellar medium by stellar winds--are one of several buffers that partially screen planetary atmospheres and surfaces from high-energy radiation. Screening by astrospheres is continually influenced by the passage of stars through the fluctuating density field of the interstellar medium (ISM)

Lyman-α Absorption from the Heliospheric Interface and Astrospheres
AIP Conference Proceedings, 2004The collision between the solar wind and the interstellar medium populates the heliosphere with hot hydrogen gas, especially in between the heliopause and bow shock. This hydrogen can produce detectable H I Lyman‐α absorption in Hubble Space Telescope (HST) observations of nearby stars.

Heliophysics: active stars, their astrospheres, and impacts on planetary environments
Contemporary Physics, 2018Relative to the period between 1850 and 1900, global temperature is now 1 ± 0.2° higher.1 The world is getting warmer in other words.

Comparison of astrospheres around cool and hot stars
2017Simulations of astrospheres around hot and cool stars have recently move into the focus of scientific research. We describe here the differences between the astrospheres around hot and cool stars. While those around the former are huge (on pc scales) because of their high stellar wind momentum flow, those around cool stars are on a AU scale and the ...
