Optimising spectroscopic observations of transiting exoplanets

Linn Boldt-Christmas, Fabio Lesjak, Ansgar Wehrhahn +4

When observing the atmospheres of transiting exoplanets using high-resolution spectroscopy, one aims to detect well-resolved spectral features with high signal-to-noise ratios (SNR…

Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT

Enric Palle, Katia Biazzo, Emeline Bolmont +56

In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapp…

Confirmation of an He I evaporating atmosphere around the 650-Myr-old sub-Neptune HD235088 b (TOI-1430 b) with CARMENES

J. Orell-Miquel, M. Lampón, M. López-Puertas +31

HD235088 (TOI-1430) is a young star known to host a sub-Neptune-sized planet candidate. We validated the planetary nature of HD235088 b with multiband photometry, refined its plane…

Retrieval of the dayside atmosphere of WASP-43b with CRIRES+

F. Lesjak, L. Nortmann, F. Yan +15

Accurately estimating the C/O ratio of hot Jupiter atmospheres is a promising pathway towards understanding planet formation and migration, as well as the formation of clouds and t…

Determination of small-scale magnetic fields on Sun-like stars in the near-infrared using CRIRES

A. Hahlin, O. Kochukhov, A. D. Rains +18

We aim to characterise the small-scale magnetic fields for a sample of 16 Sun-like stars and investigate the capabilities of the newly upgraded near-infrared (NIR) instrument CRIRE…

Characterisation of the upper atmospheres of HAT-P-32 b, WASP-69 b, GJ 1214 b, and WASP-76 b through their He I triplet absorption

M. Lampón, M. López-Puertas, J. Sanz-Forcada +14

Characterisation of atmospheres undergoing photo-evaporation is key to understanding the formation, evolution, and diversity of planets. However, only a few upper atmospheres that…
