HD 20329b: An ultra-short-period planet around a solar-type star found by TESS
F. Murgas, G. Nowak, T. Masseron +45
We used TESS light curves and HARPS-N spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate found around the star HD…
A hot sub-Neptune in the desert and a temperate super-Earth around faint M dwarfs: Color validation of TOI-4479b and TOI-2081b
E. Esparza-Borges, H. Parviainen, F. Murgas +45
We report the discovery and validation of two TESS exoplanets orbiting faint M dwarfs: TOI-4479b and TOI-2081b. We have jointly analyzed space (TESS mission) and ground based (MuSC…
Transmission spectroscopy of MASCARA-1b with ESPRESSO: Challenges of overlapping orbital and Doppler tracks
N. Casasayas-Barris, F. Borsa, E. Pallé +32
Atmospheric studies at high spectral resolution have shown the presence of molecules, neutral and ionised metals, and hydrogen in the transmission spectrum of ultra-hot Jupiters, a…
Detection of CO emission lines in the dayside atmospheres of WASP-33b and WASP-189b with GIANO
F. Yan, E. Pallé, A. Reiners +8
Ultra-hot Jupiters (UHJs) are expected to possess temperature inversion layers in their dayside atmospheres. Recent thermal emission observations have discovered several atomic and…
Validation and atmospheric exploration of the sub-Neptune TOI-2136b around a nearby M3 dwarf
K. Kawauchi, F. Murgas, E. Palle +51
The NASA space telescope is currently in the extended mission of its all-sky search for new transiting planets. Of the thousands of candidates that TESS is expected to deliv…
A tentative detection of He I in the atmosphere of GJ 1214b
J. Orell-Miquel, F. Murgas, E. Pallé +27
The $\ion{He}{I}$ 10833\, triplet is a powerful tool for characterising the upper atmosphere of exoplanets and tracing possible mass loss. Here, we analysed one transit of GJ\,1…
Detection of iron emission lines and a temperature inversion on the dayside of the ultra-hot Jupiter KELT-20b
F. Yan, A. Reiners, E. Pallé +25
Ultra-hot Jupiters (UHJs) are gas giants with very high equilibrium temperatures. In recent years, multiple chemical species, including various atoms and ions, have been discovered…
TOI-1442 b and TOI-2445 b: two potentially rocky ultra-short period planets around M dwarfs
G. Morello, H. Parviainen, F. Murgas +52
Context. Exoplanets with orbital periods of less than one day are known as ultra-short period (USP) planets. They are relatively rare products of planetary formation and evolution…
