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…
A Highly Eccentric Warm Jupiter Orbiting TIC 237913194
Martin Schlecker, Diana Kossakowski, Rafael Brahm +28
The orbital parameters of warm Jupiters serve as a record of their formation history, providing constraints on formation scenarios for giant planets on close and intermediate orbit…
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…
Discovery of a hot, transiting, Earth-sized planet and a second temperate, non-transiting planet around the M4 dwarf GJ 3473 (TOI-488)
J. Kemmer, S. Stock, D. Kossakowski +93
We present the confirmation and characterisation of GJ 3473 b (G 50--16, TOI-488.01), a hot Earth-sized planet orbiting an M4 dwarf star, whose transiting signal ($P=1.1980035\pm0.…
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…
A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
R. Luque, L. M. Serrano, K. Molaverdikhani +63
We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54+-0.03 Msun) detected during Sector 10 o…
LBT transmission spectroscopy of HAT-P-12b: confirmation of a cloudy atmosphere with no significant alkali features
F. Yan, N. Espinoza, K. Molaverdikhani +10
The hot sub-Saturn-mass exoplanet HAT-P-12b is an ideal target for transmission spectroscopy because of its inflated radius. We observed one transit of the planet with the multi-ob…
HCN production in Titan's Atmosphere: Coupling quantum chemistry and disequilibrium atmospheric modeling
Ben K. D. Pearce, Karan Molaverdikhani, Ralph E. Pudritz +2
Hydrogen cyanide (HCN) is a critical reactive source of nitrogen for building key biomolecules relevant for the origin of life. Still, many HCN reactions remain uncharacterized by…
A temperature inversion with atomic iron in the ultra-hot dayside atmosphere of WASP-189b
F. Yan, E. Pallé, A. Reiners +6
Temperature inversion layers are predicted to be present in ultra-hot giant planet atmospheres. Although such inversion layers have recently been observed in several ultra-hot Jupi…
The role of clouds on the depletion of methane and water dominance in the transmission spectra of irradiated exoplanets
Karan Molaverdikhani, Thomas Henning, Paul Mollière
Observations suggest an abundance of water and paucity of methane in the majority of observed exoplanetary atmospheres. We isolate the effect of atmospheric processes to investigat…
Orbital and spectral characterization of the benchmark T-type brown dwarf HD 19467B
A. -L. Maire, K. Molaverdikhani, S. Desidera +42
Context. Detecting and characterizing substellar companions for which the luminosity, mass, and age can be determined independently is of utter importance to test and calibrate the…
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…
The CARMENES search for exoplanets around M dwarfs. Two planets on the opposite sides of the radius gap transiting the nearby M dwarf LTT 3780
G. Nowak, R. Luque, H. Parviainen +97
We present the discovery and characterisation of two transiting planets observed by the Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d ~ 22 pc), bright (J ~ 9…
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…
EDEN: Sensitivity Analysis and Transiting Planet Detection Limits for Nearby Late Red Dwarfs
Aidan Gibbs, Alex Bixel, Benjamin Rackham +23
Small planets are common around late-M dwarfs and can be detected through highly precise photometry by the transit method. Planets orbiting nearby stars are particularly important…
