Linear Response of Rotating and Flattened Stellar Clusters: The Oblate Kuzmin–Kutuzov Stäckel Family by Kerwann Tep, Christophe Pichon, Michael S. Petersen

“…More realistic equilibria will be required to achieve a better match to the main sequence of fast–slow rotators. The corresponding code is made public.…”

Cross Helicity and the Helium Abundance as an In Situ Metric of Solar Wind Acceleration by B. L. Alterman, Raffaella D’Amicis

“…Nominally, the fast wind originates from solar sources that are continuously magnetically open to the heliosphere like coronal holes while the slow wind is from solar sources that are only intermittently open to the heliosphere like helmet streamers and pseudostreamers. …”
