The system consists of an inner moderately eccentric transiting mini-Neptune (TOI 560 b, P = 6.397438 \u00b1 0.000037 days, e = 0.294^(0.13)_(0.062)) initially discovered in the Sector 8 TESS mission observations, and a transiting mini-Neptune (TOI 560 c, P = 18.8779 \u00b1 0.0016 days) discovered in the Sector 34 observations, in a rare 1:3 orbital resonance. We utilize photometric data from TESS Spitzer, and ground-based follow-up observations to confirm the ephemerides and period of the transiting planets and vet false positive scenarios. We obtain follow-up spectroscopy and corresponding precise radial velocities (RVs) with the iSHELL spectrograph at the NASA Infrared Telescope Facility and the HIRES Spectrograph at Keck Observatory to validate the planetary nature of these signals, which we combine with published PFS RVs from Magellan Observatory. We place upper limits on the masses of both planets of <2.1 and <4.1 M_(Nep) for b and c, respectively. We apply a Gaussian Processes (GP) model to the TESS light curves to place priors on a chromatic radial velocity GP model to constrain the stellar activity of the TOI 560 host star. TOI 560 is a nearby moderately young multi-planet system with two planets suitable for atmospheric characterization with James Webb Space Telescope (JWST) and other upcoming missions. In particular, it will undergo six transit pairs separated by <6 hours before June 2027.", "doi": "10.48550/arXiv.2112.13448", "publisher": "arXiv", "publication_date": "2021-12-26" }, { "id": "authors:pq2ct-33n74", "collection": "authors", "collection_id": "pq2ct-33n74", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20220113-234547933", "type": "monograph", "title": "The California Legacy Survey III.

We find that 41\u207a\u2075\u208b\u2081\u2083%) of systems with a close-in, small planet also host an outer giant, compared to 17.6^(+2.4)_(\u22121.9)% for stars irrespective of small planet presence. This implies that small planet hosts may be enhanced in outer giant occurrence compared to all stars with 1.7\u03c3 significance.

We also find that more massive and close-in giant planets are not associated with small inner planets. Specifically, our sample indicates that small planets are less likely to host outer giant companions more massive than approximately 120 M_\u2295 and within 0.3--3 au than to host less massive or more distant giant companions, with \u223c2.2\u03c3 confidence. This implies that massive gas giants within 0.3--3 au may suppress inner small planet formation. Additionally, we compare the host-star metallicity distributions for systems with only small planets and those with both small planets and cold giants. In agreement with previous studies, we find that stars in our survey that only host small planets have a metallicity distribution that is consistent with the broader solar-metallicity-median sample, while stars that host both small planets and gas giants are distinctly metal-rich with \u223c2.3\u03c3 confidence.", "doi": "10.48550/arXiv.2112.03399", "publisher": "arXiv", "publication_date": "2021-12-06" }, { "id": "authors:2hh66-0m953", "collection": "authors", "collection_id": "2hh66-0m953", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20211124-203854733", "type": "monograph", "title": "Extreme Precision Radial Velocity Working Group Final Report", "author": [ { "family_name": "Crass", "given_name": "J.", "clpid": "Crass-Jonathan" }, { "family_name": "Gaudi", "given_name": "B.

Furthermore, it is generally acknowledged that, for the foreseeable future, the Extreme Precision Radial Velocity (EPRV) measurement technique is the only method potentially capable of detecting and measuring the masses and orbits of habitable-zone Earths orbiting nearby F, G, and K spectral-type stars from the ground. In particular, EPRV measurements with a precision of better than approximately 10 cm/s (with a few cm/s stability over many years) are required. Unfortunately, for nearly a decade, PRV instruments and surveys have been unable to routinely reach RV accuracies of less than roughly 1 m/s. Making EPRV science and technology development a critical component of both NASA and NSF program plans is crucial for reaching the goal of detecting potentially habitable Earthlike planets and supporting potential future exoplanet direct imaging missions such as the Habitable Exoplanet Observatory (HabEx) or the Large Ultraviolet Optical Infrared Surveyor (LUVOIR). In recognition of these facts, the 2018 National Academy of Sciences (NAS) Exoplanet Science Strategy (ESS) report recommended the development of EPRV measurements as a critical step toward the detection and characterization of habitable, Earth-analog planets. In response to the NAS-ESS recommendation, NASA and NSF commissioned the EPRV Working Group to recommend a ground-based program architecture and implementation plan to achieve the goal intended by the NAS. This report documents the activities, findings, and recommendations of the EPRV Working Group.", "doi": "10.48550/arXiv.2107.14291", "publisher": "arXiv", "publication_date": "2021-07-29" } ]
