Azimuthal C/O Variations in a Planet-Forming Disk
Luke Keyte, Mihkel Kama, Alice S. Booth +8
The elemental carbon-to-oxygen ratio (C/O) in the atmosphere of a giant planet is a promising diagnostic of that planet's formation history in a protoplanetary disk. Alongside effo…
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…
Sulphur monoxide emission tracing an embedded planet in the HD 100546 protoplanetary disk
Alice S. Booth, John D. Ilee, Catherine Walsh +4
Molecular line observations are powerful tracers of the physical and chemical conditions across the different evolutionary stages of star, disk and planet formation. Using the high…
Inferring the Gas-to-Dust Ratio in the Main Planet-Forming Region of Disks
Adam S. Jermyn, Mihkel Kama
Measuring the amount of gas and dust in protoplanetary disks is a key challenge in planet formation studies. Here we provide a new set of dust depletion factors and relative mass s…
Iceline Variations Driven by Protoplanetary Disc Gaps
Madelyn Broome, Oliver Shorttle, Mihkel Kama +1
The composition of forming planets is strongly affected by the protoplanetary disc's thermal structure. This thermal structure is predominantly set by dust radiative transfer and v…
Chemical Habitability: Supply and Retention of Life's Essential Elements During Planet Formation
Sebastiaan Krijt, Mihkel Kama, Melissa McClure +5
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur (CHNOPS) play key roles in the origin and proliferation of life on Earth. Given the universality of physics and chemistry,…
