Observability of ultraviolet N I lines in the atmosphere of transiting Earth-like planets
Mitchell E. Young, Luca Fossati, Colin Johnstone +5
Nitrogen is a biosignature gas that cannot be maintained in its Earth-like ratio with CO under abiotic conditions. It has also proven to be notoriously hard to detect at optica…
Non-Local Thermodynamic Equilibrium Transmission Spectrum Modelling of HD209458b
Mitchell E. Young, Luca Fossati, Tommi T. Koskinen +3
Context - Exoplanetary upper atmospheres are low density environments where radiative processes can compete with collisional ones and introduce non-local thermodynamic equilibrium…
Modelling the He I triplet absorption at 10830 Angstroms in the atmosphere of HD 209458 b
M. Lampón, M. López-Puertas, L. M. Lara +16
HD 209458b is an exoplanet with an upper atmosphere undergoing blow-off escape that has mainly been studied using measurements of the Ly-alpha absorption. Recently, high-resolution…
Cryogenic platform for coupling color centers in diamond membranes to a fiberbased microcavity
M. Salz, Y. Herrmann, A. Nadarajah +6
We operate a fiberbased cavity with an inserted diamond membrane containing ensembles of silicon vacancy centers (SiV) at cryogenic temperatures K. The setup, sample f…
Near-ultraviolet Transmission Spectroscopy of HD 209458b: Evidence of Ionized Iron Beyond the Planetary Roche Lobe
Patricio E. Cubillos, Luca Fossati, Tommi Koskinen +5
The inflated transiting hot Jupiter HD 209458b is one of the best studied objects since the beginning of exoplanet characterization. Transmission observations of this system betwee…
