The JWST weather report: Unravelling the atmospheric variability of isolated worlds using principal component analysis
Merle A. Schrader, Johanna M. Vos, Evert Nasedkin +17
The paper uses principal component analysis on JWST/NIRSpec time‑series spectra of the brown dwarf SIMP‑0136 to identify two dominant patterns of variability, linking them to tempe…
Assessing Ariel's capabilities to observe free-floating brown dwarfs
Roman Akhmetshyn, Nicolas B Cowan, Sarah Casewell
The primary goal of the Ariel space telescope is to conduct the biggest spectroscopic survey of transiting exoplanets to characterize their atmospheres and weather. We propose to e…
Coupled orbital and interior structure evolution of lava planets
Mahesh Herath, Nicolas B. Cowan, Charles-Ãdouard Boukaré +1
Lava planets likely did not form in their current orbits, instead migrating inward via orbital decay, which influenced the evolution of their magma oceans. We introduce a coupled t…
Mapping the Cloud-Driven Atmospheric Dynamics & Chemistry of an Isolated Exoplanet Analog with Harmonic Signatures
Michael K. Plummer, Francis P. Cocchini, Peter A. Kearns +12
Young planetary-mass objects and brown dwarfs near the L/T spectral transition exhibit enhanced spectrophotometric variability over field brown dwarfs. Patchy clouds, auroral proce…
Rock vapour is opaque: implications for dynamics and observations of lava planets
T. Giang Nguyen, Nicolas B. Cowan, Gunnar Montseny Gens +3
Extreme instellation on lava planets causes the rocky surface to melt and vaporize. Because the rock vapour composition is intrinsically tied to the mantle, atmospheric characteriz…
Heat Reveals What Clouds Conceal: Global Carbon & Longitudinally Asymmetric Chemistry on LTT 9779 b
Reza Ashtari, Sean Collins, Jared Splinter +17
LTT-9779 b is an ultra-hot Neptune (Rp ~ 4.7 Re, Mp ~ 29 Me) orbiting its Sun-like host star in just 19 hours, placing it deep within the "hot Neptune desert," where Neptunian plan…
