Planet-driven spiral arms in protoplanetary disks: I. Formation mechanism
Jaehan Bae, Zhaohuan Zhu
Protoplanetary disk simulations show that a single planet can excite more than one spiral arm, possibly explaining recent observations of multiple spiral arms in some systems. In t…
The Chemical Composition of Mercury
Larry R. Nittler, Nancy L. Chabot, Timothy L. Grove +1
The chemical composition of a planetary body reflects its starting conditions modified by numerous processes during its formation and geological evolution. Measurements by X-ray, g…
Elemental Abundances of Kepler Objects of Interest in APOGEE. I. Two Distinct Orbital Period Regimes Inferred from Host Star Iron Abundances
Robert F. Wilson, Johanna Teske, Steven R. Majewski +13
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) has observed 600 transiting exoplanets and exoplanet candidates from \textit{Kepler} (Kepler Objects of In…
ALMA and VLA Observations of the HD 141569 System
Jacob Aaron White, A. C. Boley, M. A. MacGregor +2
We present VLA 9 mm (33 GHz) observations of the HD 141569 system from semester 16A. The observations achieve a resolution of 0.25 arcsec ( au) and a sensitivity of $4.7~μ\…
The Architecture of the GW Ori Young Triple Star System and Its Disk: Dynamical Masses, Mutual Inclinations, and Recurrent Eclipses
Ian Czekala, Sean M. Andrews, Guillermo Torres +15
We present spatially and spectrally resolved Atacama Large Millimeter/submillimeter Array (ALMA) observations of gas and dust orbiting the pre-main sequence hierarchical triple sta…
Whole planet coupling between climate, mantle, and core: Implications for the evolution of rocky planets
Bradford J. Foley, Peter E. Driscoll
Earth's climate, mantle, and core interact over geologic timescales. Climate influences whether plate tectonics can take place on a planet, with cool climates being favorable for p…
The Pan-Pacific Planet Search VII: The most eccentric planet orbiting a giant star
Robert A. Wittenmyer, M. I. Jones, Jonathan Horner +9
Radial velocity observations from three instruments reveal the presence of a 4 M_jup planet candidate orbiting the K giant HD 76920. HD 76920b has an orbital eccentricity of 0.856$…
Thermal effects of late accretion to the crust and mantle of Mercury
Stephen J. Mojzsis, Oleg Abramov, Elizabeth A. Frank +1
Impact bombardment on Mercury in the solar system late accretion phase (ca. 4.4 to 3.8 Ga) caused considerable mechanical, chemical and thermal reworking of its silicate reservoirs…
Planet-driven spiral arms in protoplanetary disks: II. Implications
Jaehan Bae, Zhaohuan Zhu
We examine whether various characteristics of planet-driven spiral arms can be used to constrain the masses of unseen planets and their positions within their disks. By carrying ou…
Magellan/PFS Radial Velocities of GJ 9827, a late K dwarf at 30 pc with Three Transiting Super-Earths
Johanna K. Teske, Sharon X. Wang, Angie Wolfgang +5
The Kepler mission showed us that planets with sizes between that of Earth and Neptune appear to be the most common type in our Galaxy. These "super-Earths" continue to be of great…
A possible dynamically Cold Classical contact binary: (126719) 2002 CC249
Audrey Thirouin, Scott S. Sheppard
Images of the Kuiper belt object (126719) 2002 CC249 obtained in 2016 and 2017 using the 6.5m Magellan-Baade Telescope and the 4.3m Discovery Channel Telescope are presented. A lig…
A Six-Planet System Around the Star HD 34445
Steven S. Vogt, R. Paul Butler, Jennifer Burt +10
We present a new precision radial velocity dataset that reveals a multi-planet system orbiting the G0V star HD 34445. Our 18-year span consists of 333 precision radial velocity obs…
Finding the Needles in the Haystacks: High-Fidelity Models of the Modern and Archean Solar System for Simulating Exoplanet Observations
Aki Roberge, Maxime J. Rizzo, Andrew P. Lincowski +10
We present two state-of-the-art models of the solar system, one corresponding to the present day and one to the Archean Eon 3.5 billion years ago. Each model contains spatial and s…
The Science Case for an Extended Spitzer Mission
Jennifer C. Yee, Giovanni G. Fazio, Robert Benjamin +45
Although the final observations of the Spitzer Warm Mission are currently scheduled for March 2019, it can continue operations through the end of the decade with no loss of photome…
Steamworlds: atmospheric structure and critical mass of planets accreting icy pebbles
John Chambers
In the core accretion model, gas-giant planets first form a solid core, which then accretes gas from a protoplanetary disk when the core exceeds a critical mass. Here, we model the…
Formation, stratification, and mixing of the cores of Earth and Venus
Seth A. Jacobson, David C. Rubie, John Hernlund +2
Earth possesses a persistent, internally-generated magnetic field, whereas no trace of a dynamo has been detected on Venus, at present or in the past, although a high surface tempe…
PSYM-WIDE: a survey for large-separation planetary-mass companions to late spectral type members of young moving groups
Marie-Eve Naud, Étienne Artigau, René Doyon +5
We present the results of a direct-imaging survey for very large separation (100 au), companions around 95 nearby young K5-L5 stars and brown dwarfs. They are high-likelihood ca…

Marie-Eve Naud, Étienne Artigau, Jason F. Rowe +5
We present a photometric -band variability study of GU Psc b, a T3.5 co-moving planetary-mass companion (9-13) to a young (150 Myr) M3 member of the AB Dorad…
Obliquity Evolution of the Potentially Habitable Exoplanet Kepler-62f
Billy Quarles, Jason W. Barnes, Jack J. Lissauer +1
Variations in the axial tilt, or obliquity, of terrestrial planets can affect their climates and therefore their habitability. Kepler-62f is a 1.4 R planet orbiting within…
