New and Updated Rossiter-McLaughlin Measurements for Three Hot Jupiter-Hosting M Dwarfs
Drew Weisserman, Ryan Cloutier, Alexandra Rochon +12
Evidence suggests that Kozai-Lidov high-eccentricity migration (HEM) is the dominant migration channel for short-period Giant Exoplanets around M dwarf Stars (GEMS). However, it is…
The SPACE Program II: No discernible spectral features in the transmission spectrum of the sub-Neptune HD 191939 b observed with HST/WFC3
Cyril Gapp, Lorena Acuña-Aguirre, Reza Ashtari +17
The atmospheres of sub-Neptunes provide a window into their internal structure and history, shedding light on the origin of this common, but enigmatic, class of exoplanets. However…
The majority of hot Jupiters formed beyond the water ice line
Yaxing He, Bertram Bitsch, Adrien Houge +2
Atmospheric compositions of giant exoplanets can retain information about their formation environments, as volatile species condense at different temperatures in protoplanetary dis…
The panchromatic JWST dayside spectrum of WASP-121 b reveals a refractory-rich formation
K. Angelique Kahle, Paul Mollière, Laura Kreidberg +16
One path to understand how planets form is to link their present-day atmospheric composition to predictions from planet formation models. For the hottest planets, the abundances of…
Simulating the interplay between the snowline pebble flux and ongoing planet formation and migration
Danila Astrakhantsev, Sebastiaan Krijt, Sofia Savvidou +1
Pebble drift plays a central role in modern planet formation models. In this work we carry out planet formation simulations (including pebble accretion and migration) for a range o…
Locked In Ice: how Pebble Drift and Volatile Entrapment can Significantly Impact Carbon and Oxygen Ratios in Evolving Protoplanetary Discs
Joe Williams, Sebastiaan Krijt, Bertram Bitsch +2
The complex interplay between the growth, drift, and sublimation of ice-covered pebbles can strongly influence the volatile distribution and evolution of disc composition, and ther…
Aligned Stellar Obliquities for Two Hot Jupiter-hosting M Dwarfs Revealed by MAROON-X: Implications for Hot Jupiter Formation
Drew Weisserman, Erik Gillis, Ryan Cloutier +14
Hot Jupiters (HJs) are less common around early M dwarfs than around AFGK stars, suggesting that HJs may form and/or migrate via distinct pathways around different type…
Changing disc compositions via internal photoevaporation I: Solar-mass stars
Julia Lena Lienert, Bertram Bitsch, Thomas Henning
The chemical evolution of protoplanetary discs is not fully understood, several factors influence the final distribution of disc material. One such factor are inward drifting and e…
Close-in ice lines and the super-stellar C/O ratio in discs around very low-mass stars
J. Mah, B. Bitsch, I. Pascucci +1
The origin of the elevated C/O ratios in discs around late M dwarfs compared to discs around solar-type stars is not well understood. Here we endeavour to reproduce the observed di…
