Flyby-induced high-eccentricity migration and the prevalence of hot Jupiters in M67
Mika V. Kontiainen, Cathie J. Clarke, Andrew J. Winter
Few planetary systems form in isolation. Rather, interactions in their birth environments may sculpt their architectures or drive them into unstable configurations. Here we study t…
Hot Jupiter formation in dense stellar clusters: A Monte Carlo model applied to 47 Tucanae
J. A. Wirth, C. J. Clarke, A. J. Winter
We study the efficiency of high-e migration as a pathway for Hot Jupiter formation in the dense globular cluster 47 Tuc. Gravitational N-body simulations are performed to investiga…
On Hot Jupiters and Stellar Clustering: The Role of Host Star Demographics
Mika V. Kontiainen, Cathie J. Clarke, Andrew J. Winter
The variation in hot Jupiter (HJ) occurrence across stellar environments holds clues as to the dominant formation channels of these extreme planets. Recent studies suggest HJ hosts…
Disc-planet misalignment from an unstable triple system: IRAS04125
Rebecca Nealon, Jeremy L. Smallwood, Hossam Aly +5
The IRAS01425+2902 wide binary system was recently reported to have both a young planet and a puzzling geometric arrangement, where the planet and binary both orbit edge-on, but mi…
XUE. Thermochemical Modeling Suggests a Compact and Gas-Depleted Structure for a Distant, Irradiated Protoplanetary Disk
Bayron Portilla-Revelo, Konstantin V. Getman, MarÃa Claudia RamÃrez-Tannus +14
Unveiling the physical structure of protoplanetary disk is crucial for interpreting the diversity of the exoplanet population. Until recently, the census of the physical properties…
