Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT

Enric Palle, Katia Biazzo, Emeline Bolmont +56

In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapp…

An ESPRESSO view of HD 189733 system. Broadband transmission spectrum, differential rotation, and system architecture

E. Cristo, E. Esparza Borges, N. C. Santos +25

The development of state-of-the-art spectrographs has ushered in a new era in the detection and characterization of exoplanetary systems. Our objective is to utilize the high-resol…

On the 12C/13C isotopic ratio at the dawn of chemical evolution

P. Molaro, D. S. Aguado, E. Caffau +21

The known Mega and Hyper Metal-Poor (MMP-HMP) stars with [Fe/H]<-6.0 and <-5.0, respectively, likely belong to the CEMP-no class, i.e. carbon-enhanced stars with low or absent seco…

Photometric follow-up of the 20 Myr-old multi-planet host star V1298~Tau with CHEOPS and ground-based telescopes

M. Damasso, G. Scandariato, V. Nascimbeni +25

V1298 Tau hosts at least four planets. Since its discovery, this system has been a target of intensive photometric and spectroscopic monitoring. The characterisation of its archite…

A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio

M. Damasso, J. Rodrigues, A. Castro-González +52

We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…

The GAPS program at TNG XLVII: The unusual formation history of V1298 Tau

D. Turrini, F. Marzari, D. Polychroni +33

Observational data from space and ground-based campaigns reveal that the 10-30 Ma old V1298 Tau star hosts a compact and massive system of four planets. Mass estimates for the two…

An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)

A. Castro-González, O. D. S. Demangeon, J. Lillo-Box +34

Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth.…

Dynamical masses of two young transiting sub-Neptunes orbiting HD 63433

M. Mallorquín, V. J. S. Béjar, N. Lodieu +7

Although the number of exoplanets reported in the literature exceeds 5000 so far, only a few dozen of them are young planets (900 Myr). However, a complete characterization of…

Two temperate Earth-mass planets orbiting the nearby star GJ1002

A. Suárez Mascareño, E. González-Álvarez, M. R. Zapatero Osorio +42

We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ~1002 based on the analysis of the radial-velocity (RV…

The pristine nature of SMSS 16051443 revealed by ESPRESSO

D. S. Aguado, E. Caffau, P. Molaro +20

SMSS J160540.18144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H]=-6.2, which was first reported with the SkyMapper tele…
