Exploring the ultrahot Neptune LTT 9779 b with CRIRES+. Non-detection of helium transmission spectra and detection of HO on the dayside

S. Liu, F. Yan, L. Nortmann +15

Ultrahot Neptunes reside in the most extreme irradiation regime of the hot Neptune desert and remain challenging targets for atmospheric characterization because of their low plane…

Project Hephaistos -- III. Characterizing anomalous infrared sources identified as Dyson-sphere candidates

Andreas J. Korn, Matías Suazo, Erik Zackrisson +3

The infrared-flux excess of stars harbouring Dyson spheres represent one potential technosignature of extraterrestrial intelligence. In a previous Project Hephaistos paper, we high…

TSD: An inverse problem approach for recovering the exoplanetary atmosphere transmission spectrum from high-resolution spectroscopy

Nikolai Piskunov, Adam D. Rains, Linn Boldt-Christmas

Our ability to observe, detect, and characterize exoplanetary atmospheres has grown by leaps and bounds over the last 20 years, aided largely by developments in astronomical instru…

Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b. Detection of Fe and CO emission lines and evidence for inefficient heat transport

D. Cont, L. Nortmann, F. Lesjak +32

The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 K and 4500 K, an unexplored thermal regime that separates KELT-9b, the ho…

Comparative study of small-scale magnetic fields on Boo A using optical and near-infrared spectroscopy

A. Hahlin, O. Kochukhov, P. Chaturvedi +12

Magnetic field investigations of Sun-like stars, using Zeeman splitting of non-polarised spectra, in the optical and H-band have found significantly different magnetic field streng…

Retrieving wind properties from the ultra-hot dayside of WASP-189b with CRIRES

F. Lesjak, L. Nortmann, D. Cont +12

The extreme temperature gradients from day- to nightside in the atmospheres of hot Jupiters generate fast winds in the form of equatorial jets or day-to-night flows. Observations o…
