ABSTRACT Solar-type stars, which shed angular momentum via magnetized stellar winds, enter the main sequence with a wide range of rotational periods Prot. This initially contracts and has mostly vanished by age $t\sim {0.6}\, {\rm Gyr}$, after stars spin according to Skumanich relation $P_\text{rot}\propto \sqrt{t}$. Magnetohydrodynamic wind models can improve our understanding this convergence rotation periods. We present 15 young aged ∼24 Myr ∼0.13 Gyr. With previous ∼0.26 ∼0.6 Gyr we...
ABSTRACT AB Dor is a young solar-type star with surface large-scale magnetic field $10^2$ to $10^3$ times stronger than the that of Sun. Although strong fields are thought inhibit coronal mass ejections (CMEs), dimming signatures typically associated an eruptive CME were recently observed in Dor. The uninterrupted, long-duration signal suggests took place at high latitude, where it remained view as rotates. A high-latitude also consistent observations indicate hosts polar active regions. To...
