A Far-Infrared View of Astrospheres Around Young and Old Stars
A Far-Infrared View of Astrospheres Around Young and Old StarsSPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan Between their stellar winds and the surrounding medium can give rise to spectacular looking bow shocks or bow waves which are part of a star’s astrosphere. Though the basic

Cosmic rays in astrospheres [PDF]
Astronomy and Astrophysics, 2015 Cosmic rays passing through large astrospheres can be efficiently cooled inside these "cavities" in the interstellar medium. Moreover, the energy spectra of these energetic particles are already modulated in front of the astrospherical bow shocks. We study the cosmic ray flux in and around lambda Cephei as an example for an astrosphere. The large-scale

Comic ray flux anisotropies caused by astrospheres [PDF]
Astroparticle Physics, 2016 Huge astrospheres or stellar wind bubbles influence the propagation of cosmic rays at energies up to the TeV range and can act as small-scale sinks decreasing the cosmic ray flux. We model such a sink (in 2D) by a sphere of radius 10\,pc embedded within a sphere of a radius of 1\,kpc.

Shock structures of astrospheres [PDF]
Astronomy and Astrophysics, 2016 The interaction between a supersonic stellar wind and a (super-)sonic interstellar wind has recently been viewed with new interest. We here first give an overview of the modeling, which includes the heliosphere as an example of a special astrosphere.
