TL;DR
This paper reconstructs magnetic fields of exoplanet host stars and simulates their stellar winds to understand star-planet interactions and potential habitability, using adapted solar wind models for other stars.
Contribution
It introduces a method to reconstruct stellar magnetic fields from spectropolarimetric data and applies wind simulations to a specific star, expanding stellar wind modeling beyond the Sun.
Findings
Wind velocity structures are complex and correlate with magnetic topology.
Simulations provide insights into star-planet space weather interactions.
Preliminary results for $ au$ Bo"otis$ show magnetic influence on wind behavior.
Abstract
The field of exoplanetary science is one of the most rapidly growing areas of astrophysical research. As more planets are discovered around other stars, new techniques have been developed that have allowed astronomers to begin to characterise them. Two of the most important factors in understanding the evolution of these planets, and potentially determining whether they are habitable, are the behaviour of the winds of the host star and the way in which they interact with the planet. The purpose of this project is to reconstruct the magnetic fields of planet hosting stars from spectropolarimetric observations, and to use these magnetic field maps to inform simulations of the stellar winds in those systems using the Block Adaptive Tree Solar-wind Roe Upwind Scheme (BATS-R-US) code. The BATS-R-US code was originally written to investigate the behaviour of the Solar wind, and so has been…
