Dynamics of Y Dwarf Atmospheres
C. Akın, E. K. H. Lee, L. Gkouvelis +1
The global circulation regime of the coolest brown dwarfs, the Y dwarfs, remains largely unexplored. We investigate the interplay between convection, rotation, and cloud thermal fe…

Global flow regimes of hot Jupiters
C. Akın, K. Heng, J. M. Mendonça +2
In hot and ultra-hot Jupiters, stellar irradiation is a primary driver of atmospheric circulation and the wave structures that sustain it. We aim to investigate how variations in r…

Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b. Detection of Fe and CO emission lines and evidence for inefficient heat transport
D. Cont, L. Nortmann, F. Lesjak +32
The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 K and 4500 K, an unexplored thermal regime that separates KELT-9b, the ho…
