Helium Variation across Two Solar Cycles Reveals a Speed-dependent Phase Lag

B. L. AltermanORCID; Justin C. KasperORCID

<jats:title>Abstract</jats:title> <jats:p>We study the relationship between the solar wind helium-to-hydrogen abundance ratio (<jats:italic>A</jats:italic> <jats:sub>He</jats:sub>), solar wind speed (<jats:italic>v</jats:italic> <jats:sub>sw</jats:sub>), and sunspot number (SSN) over solar cycles 23 and 24. This is the first full 22 year Hale cycle measured with the <jats:italic>Wind</jats:italic> spacecraft covering a full cycle of the solar dynamo with two polarity reversals. While previous studies have established a strong correlation between <jats:italic>A</jats:italic> <jats:sub>He</jats:sub> and SSN, we show that the phase delay between <jats:italic>A</jats:italic> <jats:sub>He</jats:sub> and SSN is a monotonic increasing function of <jats:italic>v</jats:italic> <jats:sub>sw</jats:sub>. Correcting for this lag, <jats:italic>A</jats:italic> <jats:sub>He</jats:sub> returns to the same value at a given SSN over all rising and falling phases and across solar wind speeds. We infer that this speed-dependent lag is a consequence of the mechanism that depletes slow wind <jats:italic>A</jats:italic> <jats:sub>He</jats:sub> from its fast wind value during solar wind formation.</jats:p>
