For those interested in an amazing tour de force of extreme precision radial velocity measurements, check out this new paper from Shubham Kanodia (PSU) and the HPF team. It is described in this excellent post which also includes great diagrams and video content. Take a look and learn how HPF+HET is making some of the most precision measurements possible of Earth-like planets in the habitable zones of M dwarf stars!
