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…

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…

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…
