TOI-5108 b and TOI 5786 b: Two transiting sub-Saturns detected and characterized with TESS, MaHPS, and SOPHIE Open
We report the discovery and characterization of two sub-Saturns from the Transiting Exoplanet Survey Satellite ( TESS ) using high- resolution spectroscopic observations from the MaHPS spectrograph at the Wendelstein Observatory and the SO…

Confirmation of four hot Jupiters detected by TESS using follow-up spectroscopy from MaHPS at Wendelstein together with NEID and TRES Open
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 observations with the high-resolution echelle spectrograph MaHPS on t…

Small but mighty: High-resolution spectroscopy of ultra-hot Jupiter atmospheres with compact telescopes Open
When observing transmission spectra produced by the atmospheres of ultra-hot Jupiters (UHJs), large telescopes are typically the instrument of choice given the very weak signal of the planet’s atmopshere. The aim of the present study is to…
