K2-111: an old system with two planets in near-resonance
A. Mortier, M. R. Zapatero Osorio, L. Malavolta +64
This paper reports on the detailed characterisation of the K2-111 planetary system with K2, WASP, and ASAS-SN photometry as well as high-resolution spectroscopic data from HARPS-N…
Refining the transit timing and photometric analysis of TRAPPIST-1: Masses, radii, densities, dynamics, and ephemerides
Eric Agol, Caroline Dorn, Simon L. Grimm +32
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST and K2 transit time measurements, and…
AQUA: A Collection of HO Equations of State for Planetary Models
Jonas Haldemann, Yann Alibert, Christoph Mordasini +1
Water is one of the key chemical elements in planetary structure modelling. Due to its complex phase diagram, equations of state cover often only parts of the pressure - temperatur…
A super-Earth and a sub-Neptune orbiting the bright, quiet M3 dwarf TOI-1266
B. -O. Demory, F. J. Pozuelos, Y. Gomez Maqueo Chew +70
We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting the bright (), quiet, and nearby (37 pc) M3V dwarf TOI-1266. We validate the plane…
TOI-824 b: A New Planet on the Lower Edge of the Hot Neptune Desert
Jennifer A. Burt, Louise D. Nielsen, Samuel N. Quinn +54
We report the detection of a transiting hot Neptune exoplanet orbiting TOI-824 (SCR J1448-5735), a nearby (d = 64 pc) K4V star, using data from the \textit{Transiting Exoplanet Sur…
The Nature of the Radius Valley: Hints from Formation and Evolution Models
Julia Venturini, Octavio M. Guilera, Jonas Haldemann +2
The existence of a Radius Valley in the Kepler size distribution stands as one of the most important observational constraints to understand the origin and composition of exoplanet…
TESS Reveals a Short-period Sub-Neptune Sibling (HD 86226c) to a Known Long-period Giant Planet
Johanna Teske, Matías R. Díaz, Rafael Luque +44
The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here we present the detection and mass measurement of a small…
Planetary mass-radius relations across the galaxy
A. Michel, J. Haldemann, C. Mordasini +1
Planet formation theory suggests that planet bulk compositions are likely to reflect the chemical abundance ratios of their host star's photosphere. Variations in the abundance of…
Impact of the measured parameters of exoplanets on the inferred internal structure
J. F. Otegi, C. Dorn, R. Helled +3
Exoplanet characterization is one of the main foci of current exoplanetary science. For super-Earths and sub-Neptunes, we mostly rely on mass and radius measurements, which allow t…
