A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…

The Spin-Orbit Alignment of 8 Warm Gas Giant Systems

Juan I. Espinoza-Retamal, Andrés Jordán, Rafael Brahm +9

Essential information about the formation and evolution of planetary systems can be found in their architectures -- in particular, in stellar obliquity () -- as they serve as a…

Titanium chemistry of WASP-121 b with ESPRESSO in 4-UT mode

B. Prinoth, J. V. Seidel, H. J. Hoeijmakers +15

Transit spectroscopy usually relies on the integration of one or several transits to achieve the S/N necessary to resolve spectral features. Consequently, high-S/N observations of…

Vertical structure of an exoplanet's atmospheric jet stream

Julia V. Seidel, Bibiana Prinoth, Lorenzo Pino +21

Ultra-hot Jupiters, an extreme class of planets not found in our solar system, provide a unique window into atmospheric processes. The extreme temperature contrasts between their d…

A closer look at LTT 9779b: The ESPRESSO endeavour to pierce the atmospheric veil

R. Ramírez Reyes, James S. Jenkins, Elyar Sedaghati +9

The proliferation of exoplanet discoveries in exotic environments like the Neptune desert challenges our understanding of planetary atmospheres under intense irradiation. The unexp…
