Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect
Olivia Lim, René Doyon, Ryan J. MacDonald +25
In just over three years of operation, JWST has observed all seven planets of the TRAPPIST-1 system. The two innermost planets were found to have little to no atmosphere, barring t…
Early evidence for isotropic planetary obliquities in young super-Jupiter systems
Michael Poon, Marta L. Bryan, Hanno Rein +3
This decade has seen the first measurements of extrasolar planetary obliquities, characterizing how an exoplanet's spin axis is oriented relative to its orbital axis. These measure…
Diversity of Exoplanets
Diana Valencia, Amaya Moro-Martin, Johanna Teske
This review article delves into the study of low-mass exoplanets: super-Earths, mini-Neptunes and the new categories within and between that we are starting to discover. We provide…
A potential exomoon from the predicted planet obliquity of Pictoris b
Michael Poon, Hanno Rein, Dang Pham
Planet obliquity is the alignment or misalignment of a planet spin axis relative to its orbit normal. In a multiplanet system, this obliquity is a valuable signature of planet form…
Observation uncertainty effects on the precision of interior planetary parameters
Mykhaylo Plotnykov, Diana Valencia
Determining compositions of low-mass exoplanets is essential in understanding their origins. The certainty by which masses and radius are measured affects our ability to discern pl…
TRACE: a code for Time-Reversible Astrophysical Close Encounters
Tiger Lu, David M. Hernandez, Hanno Rein
We present TRACE, an almost time-reversible hybrid integrator for the planetary N-body problem. Like hybrid symplectic integrators, TRACE can resolve close encounters between parti…
