Dynamical Tides during High-Eccentricity Migration produces the Hot Jupiter Pile-up, Neptune Ridge, and Neptune Desert
J. J. Zanazzi, Morgan MacLeod, Marta L. Bryan +1
The period distribution of hot gaseous exoplanets depends strongly on mass. Clustering between the orbital periods of 3 to 5-6 days is seen for sub-Saturns ("Neptune ri…
The breaking of cold traps and onset of titanium in ultra-hot Jupiter atmospheres: WASP-189b in context
Stefan Pelletier, Romain Allart, Valentina Vaulato +56
Condensates are ubiquitous to all Solar System planets with significant (10mbar) atmospheres. The same is true for most exoplanets with characterised atmospheres, with even ultr…
An early look at how gas giants shape small planet bulk compositions
Joseph Y. Tang, Marta L. Bryan, Eve J. Lee
Gas giants may shape the reservoir of solids and gas in the inner disk in which the small planets assemble. To test this possibility, we collect a sample of 43 exoplanetary systems…
Stellar separation shapes spin-orbit alignment in visual binaries
Michael Poon, Dang Pham, Marta L. Bryan +2
Stellar binaries may form through several formation pathways, including disk or core fragmentation. Their spin-orbit angles are a signature of formation, although individual measur…
Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
Drew Weisserman, Nicole Gromek, Ryan Cloutier +98
Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…
TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS
Avidaan Srivastava, René Doyon, François Bouchy +57
A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare a…
