TOI-2147 b and TOI-6019 b: Two eccentric warm Jupiters detected and characterized with TESS and MaHPS
Luis Thomas, Louise D. Nielsen, Hanna Kellermann +42
The population of Jupiter-sized exoplanets with orbital periods between 10 and 200 days (WJs) exhibits a broad range of orbital eccentricities and system architectures, suggesting…
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…
TOI-1408: Discovery and Photodynamical Modeling of a Small Inner Companion to a Hot Jupiter Revealed by TTVs
Judith Korth, Priyanka Chaturvedi, Hannu Parviainen +60
We report the discovery and characterization of a small planet, TOI-1408 c, on a 2.2-day orbit located interior to a previously known hot Jupiter, TOI-1408 b ( d, $M=1.86\p…
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…
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…
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…
Search for giant planets in M67 V: a warm Jupiter orbiting the turn-off star S1429
Luis Thomas, Roberto Saglia, Luca Pasquini +9
Planets orbiting members of open or globular clusters offer a great opportunity to study exoplanet populations systematically as stars within clusters provide a mostly homogeneous…
Characterising a World Within the Hot Neptune Desert: Transit Observations of LTT 9779 b with HST WFC3
Billy Edwards, Quentin Changeat, Angelos Tsiaras +27
We present an atmospheric analysis of LTT 9779 b, a rare planet situated in the hot Neptune desert, that has been observed with HST WFC3 G102 and G141. The combined transmission sp…
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…
