Spectra of Earth-like Planets Through Geological Evolution Around FGKM Stars
Sarah Rugheimer, Lisa Kaltenegger
Future observations of terrestrial exoplanet atmospheres will occur for planets at different stages of geological evolution. We expect to observe a wide variety of atmospheres and…
Innocent Bystanders: Orbital Dynamics of Exomoons during Planet-Planet Scattering
Yu-Cian Hong, Sean N. Raymond, Philip D. Nicholson +1
Planet-planet scattering is the leading mechanism to explain the broad eccentricity distribution of observed giant exoplanets. Here we study the orbital stability of primordial gia…
Effects of Disk Warping on the Inclination Evolution of Star-Disk-Binary Systems
J. J. Zanazzi, Dong Lai
Several recent studies have suggested that circumstellar disks in young stellar binaries may be driven into misalignement with their host stars due to secular gravitational interac…
Eccentricity evolution during planet-disc interaction
Enrico Ragusa, Giovanni Rosotti, Jean Teyssandier +3
During the process of planet formation, the planet-discs interactions might excite (or damp) the orbital eccentricity of the planet. In this paper, we present two long ($t\sim 3\ti…
The Ability of Significant Tidal Stress to Initiate Plate Tectonics
J. J. Zanazzi, Amaury H. M. J. Triaud
Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth's climate, and may be better understood by identifying rocky plane…
Rossby Vortices in Thin Magnetized Accretion Discs
Loren Matilsky, Sergei Dyda, Richard V. E. Lovelace +1
We study the Rossby wave instability (RWI) in a thin accretion disc threaded by an initially toroidal magnetic field using the magnetohydrodynamics (MHD) code PLUTO. We find that f…
Planet Formation in Disks with Inclined Binary Companions: Can Primordial Spin-Orbit Misalignment be Produced?
J. J. Zanazzi, Dong Lai
Many hot Jupiter (HJ) systems have been observed to have their stellar spin axis misaligned with the planet's orbital angular momentum axis. The origin of this spin-orbit misalignm…
Modeling synthetic spectra for transiting extrasolar giant planets: detectability of HS and PH with JWST
Dong Wang, Yamila Miguel, Jonathan Lunine
JWSTs large aperture and wide wavelength coverage will enable it to collect the highest quality transit spectra observed so far. For exoplanetary atmospheres we expect to retrie…
How do External Companions Affect Spin-Orbit Misalignment of Hot Jupiters?
Dong Lai, Kassandra R. Anderson, Bonan Pu
Consider a planet with its orbital angular momentum axis aligned with the spin axis of its host star. To what extent does an inclined distant companion (giant planet or binary star…
Aerosols and Methane in the Ice Giant Atmospheres Inferred from Spatially Resolved, Near-Infrared Spectra: I. Uranus, 2001-2007
Michael T. Roman, Don Banfield, Peter J. Gierasch
We present a radiative transfer analysis of latitudinally resolved H (1.487-1.783 micron) and K (2.028-2.364 micron) band spectra of Uranus, from which we infer the distributions o…
What confines the rings of Saturn?
Radwan Tajeddine, Philip D. Nicholson, Pierre-Yves Longaretti +2
The viscous spreading of planetary rings is believed to be counteracted by satellite torques, either through an individual resonance or through overlapping resonances. For the A ri…
Chaotic quadruple secular evolution and the production of misaligned exomoons and Warm Jupiters in stellar multiples
Evgeni Grishin, Dong Lai, Hagai B. Perets
We study the chaotic and secular evolution of hierarchical quadruple systems in the configuration, focusing on the evolution of mutual inclination of the inner binaries as th…
True Polar Wander of Enceladus From Topographic Data
Radwan Tajeddine, Krista M. Soderlund, Peter C. Thomas +4
Many obsects in the solar system are suspected to have experience reorientation of their spin axes. As their rotation rates are slow and their shapes are nearly spherical, the form…
Dynamical phenomena at the inner edge of the Keeler gap
Radwan Tajeddine, Philip D. Nicholson, Matthew S. Tiscareno +3
We analyze several thousand Cassini ISS images in order to study the inner edge of the Keeler gap in Saturn's outer A ring. We find strong evidence for an m=32 perturbation with a…
Ohmic Dissipation in Mini-Neptunes
Bonan Pu, Diana Valencia
In the presence of a magnetic field and weakly ionizing winds, ohmic dissipation is expected to take place in the envelopes of Jovian and lower-mass planets alike. While the proces…
Asteroseismic masses of retired planet-hosting A-stars using SONG
D. Stello, D. Huber, F. Grundahl +9
To better understand how planets form, it is important to study planet occurrence rates as a function of stellar mass. However, estimating masses of field stars is often difficult.…
Trapping of Low-Mass Planets Outside the Truncated Inner Edges of Protoplanetary Discs
Ryan Miranda, Dong Lai
We investigate the migration of a low-mass () planet near the inner edge of a protoplanetary disc using two-dimensional viscous hydrodynamics simulations. We…
The Rings of Jupiter
Imke de Pater, D. P. Hamilton, M. R. Showalter +2
A review of the jovian ring system
A warmer and wetter solution for early Mars and the challenges with transient warming
Ramses M. Ramirez
The climate of early Mars has been hotly debated for decades. Although most investigators believe that the geology indicates the presence of surface water, disagreement has persist…
Secular chaotic dynamics in hierarchical quadruple systems, with applications to hot Jupiters in stellar binaries and triples
Adrian S. Hamers, Dong Lai
Hierarchical quadruple systems arise naturally in stellar binaries and triples that harbour planets. Examples are hot Jupiters (HJs) in stellar triple systems, and planetary compan…
Inclination Evolution of Protoplanetary Disks Around Eccentric Binaries
J. J. Zanazzi, Dong Lai
It is usually thought that viscous torque works to align a circumbinary disk with the binary's orbital plane. However, recent numerical simulations suggest that the disk may evolve…
Moderately Eccentric Warm Jupiters from Secular Interactions with Exterior Companions
Kassandra R. Anderson, Dong Lai
Recent studies have proposed that most warm Jupiters (WJs, giant planets with semi-major axes in the range of 0.1-1 AU) probably form in-situ, or arrive in their observed orbits th…
Exoplanet Biosignatures: Understanding Oxygen as a Biosignature in the Context of Its Environment
Victoria S. Meadows, Christopher T. Reinhard, Giada N. Arney +13
Here we review how environmental context can be used to interpret whether O2 is a biosignature in extrasolar planetary observations. This paper builds on the overview of current bi…
Improving and Assessing Planet Sensitivity of the GPI Exoplanet Survey with a Forward Model Matched Filter
Jean-Baptiste Ruffio, Bruce Macintosh, Jason J. Wang +49
We present a new matched filter algorithm for direct detection of point sources in the immediate vicinity of bright stars. The stellar Point Spread Function (PSF) is first subtract…
