Magnetic field strengths of hot giant exoplanets consistent with Solar System values
Julia V. Seidel, Vivien Parmentier, Bibiana Prinoth +29
Magnetic fields are ubiquitous in the universe. They play a key role in shaping the activity of stars, the habitability of rocky planets, and the long-term retention of planetary a…
Atmospheric composition and circulation of the ultra-hot Jupiter WASP-121b with joint NIRPS, HARPS and CRIRES+ transit spectroscopy
Valentina Vaulato, Melissa J. Hobson, Romain Allart +57
Ultra-hot Jupiters like WASP-121b provide unique laboratories for studying atmospheric chemistry and dynamics under extreme irradiation. Constraining their composition and circulat…
Parameter degeneracies associated with interpreting HST WFC3 transmission spectra of exoplanetary atmospheres
Aline Novais, Chloe Fisher, Luan Ghezzi +3
The Wide Field Camera 3 (WFC3) instrument on the Hubble Space Telescope has provided an abundance of exoplanet spectra over the years. These spectra have enabled analysis studies u…
CRIRES+ and ESPRESSO reveal an atmosphere enriched in volatiles relative to refractories on the ultra-hot Jupiter WASP-121b
Stefan Pelletier, Björn Benneke, Yayaati Chachan +11
One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation. As giant planets a…
Secrets in the shadow: High precision stellar abundances of fast-rotating A-type exoplanet host stars through transit spectroscopy
M. B. Lam, H. J. Hoeijmakers, B. Prinoth +1
Context. The spectra of fast-rotating A-type stars have strongly broadened absorption lines. This effect causes blending of the absorption lines, hindering the measurement of the a…
High-resolution transmission spectroscopy of warm Jupiters: An ESPRESSO sample with predictions for ANDES
Bibiana Prinoth, Elyar Sedaghati, Julia V. Seidel +4
Warm Jupiters are ideal laboratories for testing the limitations of current tools for atmospheric studies. The cross-correlation technique is a commonly used method to investigate…
An atlas of resolved spectral features in the transmission spectrum of WASP-189 b with MAROON-X
B. Prinoth, H. J. Hoeijmakers, B. M. Morris +10
Exoplanets in the ultra-hot Jupiter regime provide an excellent laboratory for testing the impact of stellar irradiation on the dynamics and chemical composition of gas giant atmos…
Time-resolved transmission spectroscopy of the ultra-hot Jupiter WASP-189 b
Bibiana Prinoth, H. Jens Hoeijmakers, Stefan Pelletier +14
Ultra-hot Jupiters are tidally locked with their host stars dividing their atmospheres into a hot dayside and a colder nightside. As the planet moves through transit, different reg…
The Mantis Network III: Expanding the limits of chemical searches within ultra hot-Jupiters. New detections of Ca I, V I, Ti I, Cr I, Ni I, Sr II, Ba II, and Tb II in KELT-9 b
N. W. Borsato, H. J. Hoeijmakers, B. Prinoth +5
Cross-correlation spectroscopy is an invaluable tool in the study of exoplanets. However, aliasing between spectral lines makes it vulnerable to systematic biases. This work strive…
The Mantis Network IV: A titanium cold-trap on the ultra-hot Jupiter WASP-121 b
H. J. Hoeijmakers, D. Kitzmann, B. M. Morris +10
Observations of WASP-121 b have suggested an under-abundance of titanium and titanium-oxide from its terminator region. In this study, we aim to determine whether this depletion is…
