Evidence for stellar contamination and water absorption in NGTS-5b's transmission spectra with GTC/OSIRIS
Wan-Hao Wang, Guo Chen, Chengzi Jiang +3
Transmission spectroscopy serves as a valuable tool for probing atmospheric absorption features in the terminator regions of exoplanets. Stellar surface heterogeneity can introduce…
Detection of Na in the atmosphere of the hot Jupiter HAT-P-55b
Huiyi Kang, Guo Chen, Chengzi Jiang +6
The spectral signatures of optical absorbers, when combined with those of infrared molecules, play a critical role in constraining the cloud properties of exoplanet atmospheres. We…
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…
The GTC exoplanet transit spectroscopy survey XI. Possible detection of Rayleigh scattering in the atmosphere of the Saturn-mass planet WASP-69b
F. Murgas, G. Chen, L. Nortmann +2
One of the main atmospheric features in exoplanet atmospheres, detectable both from ground- and space-based facilities, is Rayleigh scattering. In hydrogen-dominated planetary atmo…
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…
Planetary system around the nearby M dwarf GJ 357 including a transiting, hot, Earth-sized planet optimal for atmospheric characterization
R. Luque, E. Pallé, D. Kossakowski +73
We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5V star, using data from the Transiting Exoplanet Survey Satellite (TESS). GJ 357 b (TOI-562.01…
