a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on a dramatic shift in our understanding of how PRV measurements should be made. We propose a new paradigm which brings the high precision, high cadence domain of transit photometry as demonstrated by Kepler and TESS to the challenges of PRV measurements at the cm/s level. This new paradigm takes advantage of: 1) broad wavelength coverage from the UV to NIR which is only possible from space to minimize the effects of stellar activity; 2) extremely compact, highly stable, highly efficient spectrometers (R>150,000) which require the diffraction-limited imaging possible only from space over a broad wavelength range; 3) the revolution in laser-based wavelength standards to ensure cm/s precision over many years; 4) a high cadence observing program which minimizes sampling-induced period aliases; 5) exploiting the absolute flux stability from space for continuum normalization for unprecedented line-by-line analysis not possible from the ground; and 6) focusing on the bright stars which will be the targets of future imaging missions so that EarthFinder can use a ~1.5 m telescope.", "doi": "10.48550/arXiv.2006.13428", "publisher": "arXiv", "publication_date": "2020-06-24" }, { "id": "authors:c7xbe-28m60", "collection": "authors", "collection_id": "c7xbe-28m60", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190424-142121489", "type": "publication_whitepaper", "title": "Astro2020 Science White Paper: Triggered High-Priority Observations of Dynamic Solar System Phenomena", "author": [ { "family_name": "Chanover", "given_name": "Nancy", "clpid": "Chanover-N" }, { "family_name": "Wong", "given_name": "Michael H." }, { "family_name": "Greathouse", "given_name": "Thomas" }, { "family_name": "Trilling", "given_name": "David" }, { "family_name": "Conrad", "given_name": "Al" }, { "family_name": "Pater", "given_name": "Imke de" }, { "family_name": "Gaidos", "given_name": "Eric" }, { "family_name": "Cartwright", "given_name": "Richard" }, { "family_name": "Lucas", "given_name": "Michael" }, { "family_name": "Meech", "given_name": "Karen" }, { "family_name": "Orton", "given_name": "Glenn" }, { "family_name": "Pinilla-Alonso", "given_name": "Noemi" }, { "family_name": "Sayanagi", "given_name": "Kunio" }, { "family_name": "Schwamb", "given_name": "Megan E." }, { "family_name": "Tiscareno", "given_name": "Matthew" }, { "family_name": "Veillet", "given_name": "Christian" }, { "family_name": "Holler", "given_name": "Bryan" }, { "family_name": "de Kleer", "given_name": "Katherine", "orcid": "0000-0002-9068-3428", "clpid": "de-Kleer-K-R" }, { "family_name": "Hammel", "given_name": "Heidi" }, { "family_name": "Hendrix", "given_name": "Amanda" }, { "family_name": "Otarola", "given_name": "Angel" }, { "family_name": "Nixon", "given_name": "Conor" }, { "family_name": "Benecchi", "given_name": "Susan" }, { "family_name": "Simon", "given_name": "Amy" }, { "family_name": "Mandt", "given_name": "Kathleen" }, { "family_name": "Verbiscer", "given_name": "Anne" }, { "family_name": "Giles", "given_name": "Rohini" }, { "family_name": "Retherford", "given_name": "Kurt" }, { "family_name": "Fry", "given_name": "Patrick" }, { "family_name": "Bell", "given_name": "James F." }, { "family_name": "Milam", "given_name": "Stefanie" }, { "family_name": "Rivkin", "given_name": "Andy" }, { "family_name": "Luszcz-Cook", "given_name": "Statia" } ], "abstract": "Unexpected dynamic phenomena have surprised solar system observers in the past and have led to important discoveries about solar system workings.
