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.…
A Spectral Survey of WASP-19b with ESPRESSO
Elyar Sedaghati, Ryan J. MacDonald, Núria Casasayas-Barris +10
High resolution precision spectroscopy provides a multitude of robust techniques for probing exoplanetary atmospheres. We present multiple VLT/ESPRESSO transit observations of the…
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…
Modelling the He I triplet absorption at 10830 Angstroms in the atmospheres of HD 189733 b and GJ 3470 b
M. Lampón, M. López-Puertas, J. Sanz-Forcada +16
Characterising the atmospheres of exoplanets is key to understanding their nature and provides hints about their formation and evolution. High-resolution measurements of the helium…
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…
Water vapor detection in the transmission spectra of HD 209458 b with the CARMENES NIR channel
A. Sánchez-López, F. J. Alonso-Floriano, M. López-Puertas +31
Aims: We aim at detecting HO in the atmosphere of the hot Jupiter HD 209458 b and perform a multi-band study in the near infrared with CARMENES. Methods: The HO absorption…
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…
Detection of He I Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy
M. Salz, S. Czesla, P. C. Schneider +35
We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near-infra…
Multiple water band detections in the CARMENES near-infrared transmission spectrum of HD 189733 b
F. J. Alonso-Floriano, A. Sánchez-López, I. A. G. Snellen +27
Aims: We explore the capabilities of CARMENES for characterizing hot-Jupiter atmospheres by targeting multiple water bands, in particular, those at 1.15 and 1.4 m. Hubble Space…
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…
