Horace Welcome Babcock (September 13, 1912 – August 29, 2003) was an American astronomer. He was the son of Harold D. Babcock.
Career
Babcock invented and built a number of astronomical instruments, and in 1953 was the first to propose the idea of
Babcock Model, a theory for the magnetism of sunspots
.
During
Caltech and his doctorate from University of California, Berkeley.[3]
Babcock's doctoral thesis contained one of the earliest indications of dark matter. He reported measurements of the rotation curve for Andromeda which suggested that the mass-to-luminosity ratio increases radially.[4] He, however, attributed it to either absorption of light within the galaxy or modified dynamics in the outer portions of the spiral and not to any form of missing matter.
He was director of the
Caltech
from 1964 to 1978.
