Project Abstract: In the overarching quest for habitable worlds, the field of radial velocity (RV) exoplanet detection stands at a highly potent juncture as a new generation of “extreme precision” planet hunting spectrographs is deployed. Once these sophisticated systems are able to overcome prior instrumental limits, astrophysical noise or ‘jitter’ caused by stellar magnetic activity will become the fundamental obstacle to the detection of small planetary signatures. This research project will use NASA and NSF's flagship Doppler RV instrument, NEID, to study the Sun as our best target for detailed activity characterization. The PI is part of the NEID team, as well as several other extreme precision radial velocity (EPRV) instruments — therefore, this project will also involve collaboration across some of the leading exoplanet research groups as we combine resources towards a common goal.
