The refractory fraction of phosphorus in planet-forming discs
Sandipan P. D. Borthakur, Mihkel Kama, Luca Fossati +3
Context. Phosphorus (P) is an essential element for life on Earth and a potential tracer of planet formation history. However, there has been no detection of P-bearing molecules in…
Investigating Circumstellar Atomic Radiation-driven Dynamics
A. Lehtmets, M. Kama, L. Fossati +1
The interactions between stars and their orbiting planets, driven by forces such as stellar radiation and gravity, play an essential role in shaping exoplanetary atmospheres and ga…
Warm, water-depleted rocky exoplanets with surface ionic liquids: A proposed class for planetary habitability
Rachana Agrawal, Sara Seager, Iaroslav Iakubivskyi +6
The discovery of thousands of exoplanets and the emergence of telescopes capable of exoplanet atmospheric characterization have intensified the search for habitable worlds. Due to…
NLTE atmospheric modelling of the ultra-hot Jupiter WASP-178b and comparison with UV and optical observations
L. Fossati, A. G. Sreejith, T. Koskinen +6
We model the atmosphere of the ultra-hot Jupiter (UHJ) WASP-178b accounting for NLTE effects and compare synthetic transmission spectra with NUV and optical observations. We use th…
Vertical and radial distribution of atomic carbon in HD 163296
F. Urbina, J. Miley, M. Kama +1
In protoplanetary disks, atomic carbon is expected to originate from the PDR at the disk surface where CO is dissociated by UV photons coming from the stellar, or external interste…
KELT-9 and its ultra-hot Jupiter: stellar parameters, composition, and planetary pollution
Mihkel Kama, Colin P. Folsom, Adam S. Jermyn +1
KELT-9b is an ultra-hot Jupiter observed to be undergoing extreme mass loss. Its A0-type host star has a radiative envelope, which makes its surface layers prone to retaining recen…
