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…
Stacking transmission spectra of different exoplanets
James Kirk, James E. Owen
In many areas of astronomy, spectra of different objects are co-added or stacked to improve signal-to-noise and reveal population-level characteristics. As the number of exoplanets…
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…
Aerosol dynamics on hot exoplanets: the role of radiation pressure
James E. Owen, Ruth A. Murray-Clay
Aerosols appear to be ubiquitous in exoplanetary atmospheres. However because our understanding of the physical processes that govern aerosols is incomplete, their presence makes t…
BOWIE-ALIGN: Sub-stellar metallicity and carbon depletion in the aligned TrES-4b with JWST NIRSpec transmission spectroscopy
Annabella Meech, Alastair B. Claringbold, Eva-Maria Ahrer +19
The formation and migration history of a planet is expected to be imprinted in its atmosphere, in particular its carbon-to-oxygen (C/O) ratio and metallicity. The BOWIE-ALIGN progr…
The past, present and future of observations of externally irradiated disks
Planet formation environments collaboration, Megan Allen, Rossella Anania +51
Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolutio…
Carving the Edges of the Rocky Planet Population
Eve J. Lee, James E. Owen
Short-period planets provide ideal laboratories for testing star-planet interaction. Planets that are smaller than 2 are considered to be largely rocky either havin…
