Patrick VanhouckeHistorian Margaret W. #Rossiter exposed the long-standing erasure of women scientists and named it the #MatildaEffect, after Matilda Joslyn #Gage. Through decades of research, she restored hundreds of women to the scientific record and reshaped how history is written.
Dr. Alexandre Santerne 🌍The #Rossiter-#McLaughlin effect is also called the spectroscopic transit. Since the #star is rotating, one side is coming towards us and is blue-shifted while the other side is moving away from us and is red-shifted. As the planet is crossing the stellar disk, it blocks a part of the blue-, then red-shifted part. The Rossiter-McLaughlin is a radial velocity anomaly during transit.
