EOS: Atmospheric Radiative Transfer in Habitable Worlds with HELIOS

Paolo Simonetti, Giovanni Vladilo, Laura Silva +5

We present EOS, a procedure for determining the Outgoing Longwave Radiation (OLR) and top-of-atmosphere (TOA) albedo for a wide range of conditions expected to be present in the at…

The Rossiter-McLaughlin effect Revolutions: An ultra-short period planet and a warm mini-Neptune on perpendicular orbits

V. Bourrier, C. Lovis, M. Cretignier +34

Comparisons of the alignment of exoplanets with a common host star can be used to distinguish among concurrent evolution scenarios. However, multi-planet systems usually host mini-…

C/2014 UN271 (Bernardinelli-Bernstein): the nearly spherical cow of comets

Pedro H. Bernardinelli, Gary M. Bernstein, Benjamin T. Montet +64

C/2014 UN271 (Bernardinelli-Bernstein) is a comet incoming from the Oort cloud which is remarkable in having the brightest (and presumably largest) nucleus of any well-measured com…

A search of the full six years of the Dark Energy Survey for outer Solar System objects

Pedro H. Bernardinelli, Gary M. Bernstein, Masao Sako +64

We present the results of a search for outer Solar System objects in the full six years of data (Y6) from the Dark Energy Survey (DES). The DES covered a contiguous deg…

HD22496b: the first ESPRESSO standalone planet discovery

J. Lillo-Box, J. P. Faria, A. Suárez Mascareño +32

The ESPRESSO spectrograph is a new powerful tool to detect and characterize extrasolar planets. Its design allows unprecedented radial velocity precision (down to a few tens of cm/…

Warm terrestrial planet with half the mass of Venus transiting a nearby star

Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42

The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…

Into the Storm: Diving into the winds of the ultra hot Jupiter WASP-76 b with HARPS and ESPRESSO

J. V. Seidel, D. Ehrenreich, A. Allart +26

Despite swift progress in the characterisation of exoplanet atmospheres in composition and structure, the study of atmospheric dynamics has not progressed at the same speed. While…

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…
