The impact of disc photoevaporation on the long-term evolution of giant planets in mean motion resonances

Emmanuel J. Greenfield, James E. Owen

We investigate the long-term impact of disc photoevaporation on the dynamical stability and evolution of giant planet pairs in mean motion resonances. Using two-dimensional hydrody…

BOWIE-ALIGN: Sub-solar C/O ratio and metallicity atmosphere of the misaligned hot Jupiter HAT-P-30b

Alastair B. Claringbold, Chloe E. Fisher, James Kirk +18

We present the JWST NIRSpec/G395H transmission spectrum of the misaligned hot Jupiter HAT-P-30b from 2.8--5.2 m as part of the BOWIE-ALIGN survey, a comparative survey designed…

A young progenitor for the most common planetary systems in the Galaxy

John H. Livingston, Erik A. Petigura, Trevor J. David +39

The Galaxy's most common known planetary systems have several Earth-to-Neptune-size planets in compact orbits. At small orbital separations, larger planets are less common than the…

Resolving the flat-spectrum conundrum: clumpy aerosol distributions in sub-Neptune atmospheres

James E. Owen, James Kirk

Transmission spectroscopy of sub-Neptunes was expected to reveal their compositions and hence origins, yet many show flat near- to mid-infrared spectra. Such spectra can be explain…

A dust condensation instability in AGN atmospheres: failed winds and the broad line region

James E. Owen, Douglas N. C. Lin

Active galactic nuclei (AGN) are important drivers of galactic evolution; however, the underlying physical processes governing their properties remain uncertain. In particular, the…

BOWIE-ALIGN: Weak spectral features in KELT-7b's JWST NIRSpec/G395H transmission spectrum imply a high cloud deck or a low-metallicity atmosphere

Eva-Maria Ahrer, Charlotte Fairman, James Kirk +20

Hot Jupiters and their atmospheres are prime targets for transmission spectroscopy due to their extended atmospheres and the corresponding large signal-to-noise, providing the best…
