The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations
Conor A. Nixon, Bruno Bézard, Thomas Cornet +42
Saturn's moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan's northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017)…
The CH abundance in Jupiter's upper atmosphere
A. Sánchez-López, M. López-Puertas, M. García-Comas +3
Hydrocarbon species, and in particular CH, play a key role in the stratosphere--thermosphere boundary of Jupiter, which occurs around the -bar pressure level. Previous analy…
Detection of the hydrogen Balmer lines in the ultra-hot Jupiter WASP-33b
F. Yan, A. Wyttenbach, N. Casasayas-Barris +24
Ultra-hot Jupiters (UHJs) are highly irradiated giant exoplanets with extremely high day-side temperatures, which lead to thermal dissociation of most of the molecular species. It…
The widest broadband transmission spectrum (0.38-1.71 m) of HD 189733b from ground-based chromatic Rossiter-McLaughlin observations
M. Oshagh, F. F. Bauer, M. Lafarga +22
Multiband photometric transit observations (spectro-photometric) have been used mostly so far to retrieve broadband transmission spectra of transiting exoplanets in order to study…
Discriminating between hazy and clear hot-Jupiter atmospheres with CARMENES
A. Sánchez-López, M. López-Puertas, I. A. G. Snellen +20
Context: Relatively large radii of some hot Jupiters observed in the ultraviolet (UV) and blue-optical are generally interpreted to be due to Rayleigh scattering by high-altitude h…
Detection of Fe I and Fe II in the atmosphere of MASCARA-2b using a cross-correlation method
M. Stangret, N. Casasayas-Barris, E. Pallé +3
Ultra-hot Jupiters are gas giants planets whose dayside temperature, due to the strong irradiation received from the host star, is greater than 2200 K. These kind of objects are pe…
Is there NaI in the atmosphere of HD 209458b? Effect of the centre-to-limb variation and Rossiter-McLaughlin effect in transmission spectroscopy studies
N. Casasayas-Barris, E. Palle, F. Yan +22
HD 209458b was the first transiting planet discovered, and the first for which an atmosphere, in particular NaI, was detected. With time, it has become one of the most frequently s…
Ionized calcium in the atmospheres of two ultra-hot exoplanets WASP-33b and KELT-9b
F. Yan, N. Casasayas-Barris, K. Molaverdikhani +25
Ultra-hot Jupiters are emerging as a new class of exoplanets. Studying their chemical compositions and temperature structures will improve the understanding of their mass loss rate…
ESA Voyage 2050 White Paper: Detecting life outside our solar system with a large high-contrast-imaging mission
Ignas Snellen, Simon Albrecht, Guillem Anglada-Escude +64
In this white paper, we recommend the European Space Agency plays a proactive role in developing a global collaborative effort to construct a large high-contrast imaging space tele…
The CARMENES search for exoplanets around M dwarfs. Two temperate Earth-mass planet candidates around Teegarden's Star
M. Zechmeister, S. Dreizler, I. Ribas +182
Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0V), the star shows relatively little…
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…
The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
ALMA Discovery of Dust Belts Around Proxima Centauri
Guillem Anglada, Pedro J. Amado, Jose L. Ortiz +19
Proxima Centauri, the star closest to our Sun, is known to host at least one terrestrial planet candidate in a temperate orbit. Here we report the ALMA detection of the star at 1.3…
Titan Science with the James Webb Space Telescope (JWST)
Conor A. Nixon, Richard K. Achterberg, Mate Adamkovics +12
The James Webb Space Telescope (JWST), scheduled for launch in 2018, is the successor to the Hubble Space Telescope (HST) but with a significantly larger aperture (6.5 m) and advan…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
Jupiter as an exoplanet: UV to NIR transmission spectrum reveals hazes, a Na layer and possibly stratospheric H2O-ice clouds
P. Montañes-Rodriguez, B Gonzalez-Merino, E. Palle +2
Currently, the analysis of transmission spectra is the most successful technique to probe the chemical composition of exoplanet atmospheres. But the accuracy of these measurements…
