Description
The solar wind in the preset is well studied using remote and in situ measurements. Not much is known about the evolution of the solar wind over the lifetime of our star, posing the question, what was the solar wind like over evolutionary timescales? To answer this question we turn to solar-like stars that we can use as proxies for the solar wind at different ages. There currently exists little information on the winds of solar-like stars as observations are difficult to conduct due to their rarefied nature which leads to diminished emissions. We present 3D MHD simulations of a sample of solar analogues from which we determine global wind parameters such as mass- and angular momentum-loss rates. From our simulations we calculated the thermal bremsstrahlung expected from these winds using a developed numerical tool, comparing them to the sensitivities of current and future radio telescopes.
