A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations

F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201

This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…

An extended low-density atmosphere around the Jupiter-sized planet WASP-193 b

Khalid Barkaoui, Francisco J. Pozuelos, Coel Hellier +32

Gas giants transiting bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets exhibit certain average character…

Activity time series of old stars from late F to early K VI. Exoplanet mass characterisation and detectability in radial velocity

Nadège Meunier, Romain Pous, Sophia Sulis +2

Stellar variability impacts radial velocities at various timescales and therefore the detectability of exoplanets and the mass determination based on this technique. It is necessar…

Primordial or Secondary? Testing models of debris disk gas with ALMA

Gianni Cataldi, Yuri Aikawa, Kazunari Iwasaki +13

The origin and evolution of gas in debris disks is still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed. So far, obs…

A subsolar oxygen abundance or a radiative region deep in Jupiter revealed by thermochemical modelling

Thibault Cavalié, Jonathan Lunine, Olivier Mousis

Jupiter's deep abundances help to constrain the formation history of the planet and the environment of the protoplanetary nebula. Juno recently measured Jupiter's deep oxygen abund…

Emission line variability of young 10-30 Mjup companions : I. The case of GQ Lup b and GSC 06214-00210 b

Dorian Demars, Mickael Bonnefoy, Catherine Dougados +10

Emission lines indicative of active accretion have been seen on a handful of low-mass companions (M < 30 MJup) to stars. Line variability is ubiquitous on stellar accretors but has…

A re-investigation of debris disc halos

Philippe Thebault, Johan Olofsson, Quentin Kral

A significant fraction of debris discs consist of a bright ring beyond which extends a wide halo. Such a halo should be made of small grains produced in the ring of parent bodies (…

Stirred but not shaken: a multi-wavelength view of HD 16743's debris disc

Jonathan P. Marshall, Julien Milli, Elodie Choquet +6

Planetesimals -- asteroids and comets -- are the building blocks of planets in protoplanetary discs and the source of dust, ice and gas in debris discs. Along with planets they com…
