CARMENES detection of the CaII infrared triplet and possible evidence of HeI in the atmosphere of WASP-76b

N. Casasayas-Barris, J. Orell-Miquel, M. Stangret +25

Ultra-hot Jupiters are highly irradiated gas giants with equilibrium temperatures typically higher than 2000K. Atmospheric studies of these planets have shown that their transmissi…

Detection of Fe and evidence for TiO in the dayside emission spectrum of WASP-33b

D. Cont, F. Yan, A. Reiners +23

Theoretical studies predict the presence of thermal inversions in the atmosphere of highly irradiated gas giant planets. Recent observations have identified these inversion layers.…

Evidence of energy-, recombination-, and photon-limited escape regimes in giant planet H/He atmospheres

M. Lampón, M. López-Puertas, S. Czesla +14

Hydrodynamic escape is the most efficient atmospheric mechanism of planetary mass loss and has a large impact on planetary evolution. Three hydrodynamic escape regimes have been id…

A He I upper atmosphere around the warm Neptune GJ 3470b

E. Palle, L. Nortmann, N. Casasayas-Barris +24

High resolution transit spectroscopy has proven to be a reliable technique for the characterization of the chemical composition of exoplanet atmospheres. Taking advantage of the br…

He I 10830 Å in the transmission spectrum of HD 209458 b

F. J. Alonso-Floriano, I. A. G. Snellen, S. Czesla +27

Context: Recently, the He I triplet at 10830 Å has been rediscovered as an excellent probe of the extended and possibly evaporating atmospheres of close-in transiting planets. This…

Retrieval of nitric oxide in the mesosphere and lower thermosphere from SCIAMACHY limb spectra

Stefan Bender, Miriam Sinnhuber, John P. Burrows +3

We use the ultra-violet (UV) spectra in the range 230--300 nm from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) to retrieve the nitric oxid…

Exploring Extreme Space Weather Factors of Exoplanetary Habitability

V. S. Airapetian, V. Adibekyan, M. Ansdell +46

It is currently unknown how common life is on exoplanets, or how long planets can remain viable for life. To date, we have a superficial notion of habitability, a necessary first s…
