Your second citation only cites your first, which is not a debunking but a comment in an interview - which says 75% of the gap is due to career choice - but the link I provided shows gaps by career, making that distinction moot.
Apologies - I included the citation because I just copied someone else's comment that I found appropriate. I felt bad not citing where it was from.
With regard to your article - it does not analyze difference in hours worked. Perhaps someone working 3 days a week after taking a few years off for maternity leave should earn less than someone working full-time with no experience gaps? Please see my other comment in this thread that cites more thorough research.
