The Herculis system solved after nearly three centuries

Marcus L. Marcussen, Mikkel N. Lund, Frank Grundahl +11

Herculis is a bright, nearby quadruple system. Its brightest member, Her Aa, displays solar-like oscillations, establishing the system as a crucial benchmark for asterose…

TOI-1333Ab is on a well-aligned orbit. An aligned hot Jupiter around an F-type star with a mutually inclined stellar companion

E. Knudstrup, M. L. Marcussen, S. H. Albrecht +2

Spin-orbit obliquity measurements of hot-Jupiter systems constrain giant planet migration and tidal evolution. In binary systems, combining stellar obliquities with the orbit-orbit…

Aligned, Misaligned and Polar Orbits of Hot Jupiters: Measuring Spin-Orbit Angles via Doppler Tomography with HARPS-N

Z. Balkóová, J. Žák, M. Skarka +4

Although the migration of hot Jupiters is not yet fully understood, measurements of the projected spin-orbit angle λ help shed light on the processes involved. Here we present Dop…

TOI-3862 b: A dense super-Neptune deep in the hot Neptune desert

Ilaria Carleo, Amadeo Castro-González, Enric Pallé +61

The structure and evolution of close-in exoplanets are shaped by atmospheric loss and migration processes, which give rise to key population features such as the hot Neptune desert…

Precise mass and radius determination for two new and one known Neptune-sized planets around G Dwarf hosts

Ilaria Carleo, Grzegorz Nowak, Felipe Murgas +56

As part of the KESPRINT collaboration, we present the discovery and characterization of three exoplanets in the sub-Neptune to super-Neptune regime, spanning key regions of the exo…

A four-planet system orbiting the old thick disk star TOI-1203

D. Gandolfi, A. Alnajjarine, L. M. Serrano +120

TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…
