The GTC exoplanet transit spectroscopy survey X. Stellar spots versus Rayleigh scattering: the case of HAT-P-11b
F. Murgas, G. Chen, E. Pallé +2
Rayleigh scattering in a hydrogen-dominated exoplanet atmosphere can be detected from ground or space based telescopes, however, stellar activity in the form of spots can mimic Ray…
Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b
Lisa Nortmann, Enric Pallé, Michael Salz +25
Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, affecting their physical and chemical evolution. Studies of atmospheric escape from ex…
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…
The GTC exoplanet transit spectroscopy survey IX. Detection of Haze, Na, K, and Li in the super-Neptune WASP-127b
G. Chen, E. Palle, L. Welbanks +9
Exoplanets with relatively clear atmospheres are prime targets for detailed studies of chemical compositions and abundances in their atmospheres. Alkali metals have long been sugge…
Na I and H absorption features in the atmosphere of MASCARA-2b/KELT-20b
N. Casasayas-Barris, E. Palle, F. Yan +9
We have used the HARPS-North high resolution spectrograph (=115 000) at TNG to observe one transit of the highly irradiated planet MASCARA-2b/KELT-20b. Using only one…
