Dynamical evolution and dissolution timescale of young stellar clusters in the Orion star-forming complex

Sergio Sánchez-Sanjuán, Ángeles Pérez-Villegas, Jesús Hernández +1

We present a comprehensive analysis of the Orion star-forming complex (OSFC), combining structural, kinematic, and dynamical information to constrain the present-day state and futu…

gr8stars II : judgement day for spectroscopic parameter model systematics

Alix Violet Freckelton, Annelies Mortier, Megan Bedell +18

Many areas of astrophysics, including exoplanetary studies, rely on precise and accurate stellar parameters. This demands that uncertainties on these parameters truly reflect all b…

A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)

A. Sozzetti, M. Damasso, A. S. Bonomo +45

[Abridged] We exploit the extreme radial velocity (RV) precision of the ultra-stable echelle spectrograph ESPRESSO on the VLT to unveil the physical properties of the transiting su…

Six transiting planets and a chain of Laplace resonances in TOI-178

A. Leleu, Y. Alibert, N. C. Hara +152

Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…

The atmosphere of HD 209458b seen with ESPRESSO. No detectable planetary absorptions at high resolution

N. Casasayas-Barris, E. Palle, M. Stangret +37

We observed two transits of the iconic gas giant HD 209458b between 380 and 780 nm, using the high-resolution ESPRESSO spectrograph. The derived planetary transmission spectrum exh…

Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds

Gaia Collaboration, X. Luri, L. Chemin +417

We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
