This item is a proper name referring to a specific person; its encyclopedic meaning (a Dutch astronomer) is referential and cannot be derived from the constituent name parts 'Jan', 'Hendrix', and 'Oort'. Knowing each word as a name does not allow a B1 learner to infer the biographical/professional information, so the expression is opaque.

Etymology

Jan Hendrix Oort was a Dutch scientist who studied the stars; he showed the Milky Way turns and suggested there is a distant 'Oort cloud' of icy objects around the Sun. That's why his name is used for that idea.
