The Sun loses angular momentum through the solar wind, at a rate which is challenging to model or measure. We have produced a new direct measurement using data from the Wind spacecraft over the last 25 years. Accepted to ApJL and on arxiv https://t.co/HmQPM8ELCm (1/4)
We show how the wind torques vary, based on MHD simulations (see Figure), and compare these to the torques required to fit the observed spin-evolution of low-mass stars. We find the spin-ev torques to be 3-30 times larger than the MHD torques.. (2/2) Read:https://t.co/TjSETp1HM1
How do the angular momentum loss rates of low-mass stars vary in time? In our new paper, @AWESoMeStarsERC examines stars which have been repeatedly monitored using Zeeman-Doppler imaging, and have mass loss rates constrained by Ly-alpha obs. (1/2) @AstroVictorSee@UoE_Astro

RT @AdamF_Astro Interested in the current spin down rate of the Sun? Look no further! I've just published some work using results from my MHD simulations: https://t.co/Og9VC5EaAI Our results indicate the torque on the Sun due to the solar wind is less th…
Hurray! Poster 86 at #CoolStars20 If you would like to see how the angular momentum loss rate of the Sun has varied over the last 22 years! @AWESoMeStarsERC
