Brown dwarf variability directly probes atmospheric dynamics beyond the Solar System, and recent JWST time-resolved spectroscopy has opened a new window into these processes. Principal component analy...

Static retrieval frameworks are leading tools for interpreting exoplanet observations, yet time-independent modelling leaves them prone to degeneracy and unable to resolve exoplanets' histories. The c...

Exoplanet characterization relies on precise measurements of planetary orbital and physical parameters. This is particularly important for planetary dynamics and atmospheric evolution, as orbital para...

Mapping the Cloud-driven Atmospheric Dynamics and Chemistry of an Isolated Exoplanet Analog with Harmonic Signatures, Plummer, Michael K., Cocchini, Francis P., Kearns, Peter A., McCarthy, Allison M., Artigau, Étienne, Cowan, Nicolas B., Akhmetshyn, Roman, Vos, Johanna M., Nasedkin, Evert, Visscher, Channon, Benneke, Björn, Doyon, René, Metchev, Stanimir A., Rowe, Jason F., Suárez, Genaro

Ultra-cool T- (T$_{\mathrm{eff}} \approx$ 500 - 1200 K) and Y-dwarfs (T$_{\mathrm{eff}}$ $\lessapprox 500$ K) have historically been found only a few hundred parsecs from the Sun. The sensitivity and ...

Young planetary-mass objects and brown dwarfs near the L/T spectral transition exhibit enhanced spectrophotometric variability over field brown dwarfs. Patchy clouds, auroral processes, stratospheric ...

The new infrared spectrograph NIRPS, built with the participation of the Instituto de Astrofísica de Canarias (IAC) and installed on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile, has...

In the latest of our #UndergradResearch series, discover how Diya Talesara uses IR spectroscopy to study biosignatures in exoplanet data.

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-dependent Variability Driven by Multiple Mechanisms, McCarthy, Allison M., Vos, Johanna M., Muirhead, Philip S., Bil...
