Companion Architectures of Sub-Saturns: Distinct Migration Pathways Across the Neptunian Landscape

Luis Thomas, Louise D. Nielsen, Alex J. Cridland +2

Close-in sub-Saturns (4 - 8.5 R) are depleted in the Neptunian desert, accumulate in a narrow overdensity near P = 3.2 - 5.7 d (the Neptunian ridge), and thin out into the…

Galaxy Luminosity Function of the Coma Cluster from Deep Wendelstein Imaging Data

Raphael Zöller, Matthias Kluge, Ralf Bender +9

We derive the band galaxy luminosity function (GLF) of quenched resolved galaxies in the Coma cluster from a deep-imaging survey with around the c…

Evidence of a gap in the envelope mass fraction of sub-Saturns

Luis Thomas, Louise D. Nielsen, Lorena Acuña-Aguirre +1

Under the core-accretion model, gas giants form via runaway accretion. This process starts when the mass of the accreted envelope becomes equal to the mass of the core. Here, we mo…

Confirmation of four hot Jupiters detected by TESS using follow-up spectroscopy from MaHPS at Wendelstein together with NEID and TRES

Juliana Ehrhardt, Luis Thomas, Hanna Kellermann +57

We report the confirmation and characterization of four hot Jupiter-type exoplanets initially detected by TESS: TOI-1295 b, TOI-2580 b, TOI-6016 b, and TOI-6130 b. Using observatio…

TOI-5108 b and TOI 5786 b: Two transiting sub-Saturns detected and characterized with TESS, MaHPS and SOPHIE

Luis Thomas, Guillaume Hébrard, Hanna Kellermann +44

We report the discovery and characterization of two sub-Saturns from the Transiting Exoplanet Survey Satellite (\textit{TESS}) using high-resolution spectroscopic observations from…
