The Earth transiting the Sun as seen from Jupiter's moons: detection of an inverse Rossiter-McLaughlin effect produced by the opposition surge of the icy Europa
Earth transit in front of the sun as seen from Jupiter.
Model of the inverse Rossiter–McLaughlin RV drift induced by an increase in the Solar emissivity in the region behind the Earth’s transit trajectory due to the opposition surge. The thin black line shows the drift expected from a small area moving with the Earth, while the thick line shows a drift coming from a larger area with a radius of about 10 arcminutes required to match the start of the radial velocity drift. The blue dotted line shows the expected Rossiter–McLaughlin effect amplified by a factor of 50. The inverse RM effect detected is about 400 times larger than the expected RM due to the Earth’s transit.
