Effects of Outer Giant Planets on In Situ Formation of Inner Super-Earths
Phoebe Sandhaus, Rebekah I. Dawson, Mariah G. MacDonald +2
Recent studies have found an observational correlation between the presence of outer giant planets and inner super-Earths, which implies that outer giants do not suppress the forma…
Effects of Pebble Accretion Isolation Mass on Observable Exoplanet Properties
Lucas Brefka, Rebekah I. Dawson, Mariah G. MacDonald +2
The Kepler Mission has discovered a plethora of planetary systems with super-Earth sized planets. These systems exhibit many properties, from widely-spaced planets with non-negligi…
Signatures of Atmospheric Mass Loss and Planet Migration in the Time Evolution of Short-Period Transiting Exoplanets
Rachel B. Fernandes, Galen J. Bergsten, Gijs D. Mulders +19
Comparative studies of young and old exoplanet populations offer a glimpse into how planets may form and evolve with time. We present an occurrence rate study of short-period (1…
TOI-1859b: A 64-Day Warm Jupiter on an Eccentric and Misaligned Orbit
Jiayin Dong, Songhu Wang, Malena Rice +31
Warm Jupiters are close-in giant planets with relatively large planet-star separations (i.e., ). Given their weak tidal interactions with their host stars, meas…
Longterm Stability of Planetary Systems formed from a Transitional Disk
Rory Bowens, Andrew Shannon, Rebekah Dawson +1
Transitional disks are protoplanetary disks with large and deep central holes in the gas, possibly carved by young planets. Dong, R., & Dawson, R. 2016, ApJ, 825, 7 simulated syste…
Statistical Analysis of the Dearth of Super-eccentric Jupiters in the Kepler Sample
Jonathan M. Jackson, Rebekah I. Dawson, Billy Quarles +1
Hot Jupiters may have formed in situ, or been delivered to their observed short periods through one of two categories of migration mechanisms: disk migration or high-eccentricity m…
Millimeter Dust Emission and Planetary Dynamics in the HD 106906 System
Anna Fehr, A. Meredith Hughes, Rebekah I. Dawson +10
Debris disks are dusty, optically thin structures around main sequence stars. HD 106906AB is a short-period stellar binary, host to a wide separation planet, HD 106906b, and a debr…
TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star
Alexis Heitzmann, George Zhou, Samuel N. Quinn +47
We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< Myr). This planet stands o…
Stellar obliquities in exoplanetary systems
Simon H. Albrecht, Rebekah I. Dawson, Joshua N. Winn
The rotation of a star and the revolutions of its planets are not necessarily aligned. This article reviews the measurement techniques, key findings, and theoretical interpretation…
Nature vs. Nurture: Investigating the Effects of Measurement Uncertainties in the Assessment of Potential Trends Between Planetary and Stellar Properties
Emily D. Safsten, Rebekah I. Dawson
Correlations between planetary and stellar properties, particularly age, can provide insight on planetary formation and evolution processes. However, the underlying source of such…
NEID Rossiter-McLaughlin Measurement of TOI-1268b: A Young Warm Saturn Aligned with Its Cool Host Star
Jiayin Dong, Chelsea X. Huang, George Zhou +56
Close-in gas giants present a surprising range of stellar obliquity, the angle between a planet's orbital axis and its host star's spin axis. It is unclear whether the obliquities…
TOI-3362b: A Proto-Hot Jupiter Undergoing High-Eccentricity Tidal Migration
Jiayin Dong, Chelsea X. Huang, George Zhou +39
High-eccentricity tidal migration is a possible way for giant planets to be emplaced in short-period orbits. If it commonly operates, one would expect to catch proto-Hot Jupiters o…
From Warm Planets to Perpendicular Hot Planets
Rebekah I. Dawson, Simon H. Albrecht
High eccentricity tidal migration (HEM) is a promising channel for the origins of hot Jupiters and hot Neptunes. In the typical HEM scenario, a planet forms beyond the ice line, bu…
A pair of warm giant planets near the 2:1 mean motion resonance around the K-dwarf star TOI-2202
Trifon Trifonov, Rafael Brahm, Nestor Espinoza +37
TOI-2202 b is a transiting warm Jovian-mass planet with an orbital period of P=11.91 days identified from the Full Frame Images data of five different sectors of the TESS mission.…
A Preponderance of Perpendicular Planets
Simon H. Albrecht, Marcus L. Marcussen, Joshua N. Winn +2
Observing the Rossiter-McLaughlin effect during a planetary transit allows the determination of the angle between the sky projections of the star's spin axis and the planet's o…
Warm Jupiters in TESS Full-Frame Images: A Catalog and Observed Eccentricity Distribution for Year 1
Jiayin Dong, Chelsea X. Huang, Rebekah I. Dawson +57
Warm Jupiters -- defined here as planets larger than 6 Earth radii with orbital periods of 8--200 days -- are a key missing piece in our understanding of how planetary systems form…
Hot Jupiters: Origins, Structure, Atmospheres
Jonathan J. Fortney, Rebekah I. Dawson, Thaddeus D. Komacek
We provide a brief review of many aspects of the planetary physics of hot Jupiters. Our aim is to cover most of the major areas of current study while providing the reader with add…
A backward-spinning star with two coplanar planets
Maria Hjorth, Simon Albrecht, Teruyuki Hirano +5
It is widely assumed that a star and its protoplanetary disk are initially aligned, with the stellar equator parallel to the disk plane. When observations reveal a misalignment bet…
Precise transit and radial-velocity characterization of a resonant pair: a warm Jupiter TOI-216c and eccentric warm Neptune TOI-216b
Rebekah I. Dawson, Chelsea X. Huang, Rafael Brahm +53
TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS Mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit transit timing…
Observable Predictions from Perturber-coupled High-eccentricity Tidal Migration of Warm Jupiters
Jonathan M. Jackson, Rebekah I. Dawson, Andrew Shannon +1
The origin of warm Jupiters (gas giant planets with periods between 10 and 200 days) is an open question in exoplanet formation and evolution. We investigate a particular migration…
Chains of Planets in Mean Motion Resonances Arising from Oligarchic Growth
Sarah J. Morrison, Rebekah I. Dawson, Mariah G. MacDonald
Exoplanet systems with multiple planets in mean motion resonances have often been hailed as a signpost of disk driven migration. Resonant chains like Kepler-223 and Kepler-80 consi…
Nature vs. nurture: a Bayesian framework for assessing apparent correlations between planetary orbital properties and stellar ages
Emily D. Safsten, Rebekah I. Dawson, Angie Wolfgang
Many exoplanets have orbital characteristics quite different from those seen in our own solar system, including planets locked in orbital resonances and planets on orbits that are…
