The Ophiuchus DIsk Survey Employing ALMA (ODISEA): A Unified Evolutionary Sequence of Planet-Driven Substructures Explaining the Diversity of Disk Morphologies

Santiago Orcajo, Lucas A. Cieza, Octavio Guilera +21

Understanding the origin of substructures in protoplanetary disks and their connection to planet formation is currently one of the main challenges in astrophysics. While some disks…

From super-Earths to sub-Neptunes: Observational constraints and connections to theoretical models

Léna Parc, François Bouchy, Julia Venturini +2

We have updated the PlanetS catalog of transiting planets with precise and robust mass and radius measurements and use this catalog to explore mass-radius (M-R) diagrams. On the on…

A fading radius valley towards M-dwarfs, a persistent density valley across stellar types

Julia Venturini, María Paula Ronco, Octavio M. Guilera +3

The radius valley separating super-Earths from mini-Neptunes is a fundamental benchmark for theories of planet formation and evolution. Observations show that the location of the r…

Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815

Angelica Psaridi, Hugh Osborn, François Bouchy +130

We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…

A radius valley between migrated steam worlds and evaporated rocky cores

Remo Burn, Christoph Mordasini, Lokesh Mishra +4

The radius valley (or gap) in the observed distribution of exoplanet radii, which separates smaller super-Earths from larger sub-Neptunes, is a key feature that theoretical models…

Constraining the reflective properties of WASP-178b using Cheops photometry

I. Pagano, G. Scandariato, V. Singh +79

Multiwavelength photometry of the secondary eclipses of extrasolar planets is able to disentangle the reflected and thermally emitted light radiated from the planetary dayside. Thi…
