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…
51 Peg b revisited with VLT/CRIRES+. Constraints on atmospheric thermal structure, chemical composition, and an alternative orbital solution
D. Cont, L. Nortmann, F. Lesjak +18
So far, the atmospheres of non-transiting exoplanets remain poorly explored, and the potential of high-resolution spectroscopy for determining key planetary parameters beyond their…
The CARMENES search for exoplanets around M dwarfs. A homogeneous catalogue of projected rotational velocities accounting for limb-darkening
R. Varas, G. Morello, M. Zechmeister +18
Stellar rotation is closely linked to both age and magnetic activity. Through gyrochronology, it provides a means to estimate stellar ages and trace the evolution of planetary syst…
Cloudy with a chance of metals: Indications of CO in the atmosphere of GJ 1214 b from high-resolution K-band spectroscopy
L. Nortmann, D. Cont, F. Lesjak +13
Sub-Neptune exoplanets frequently exhibit muted transmission spectra, with GJ 1214 b being the most prominent example. Following years of intense observing campaigns yielding featu…
Constraining an exoplanets magnetic field using star-planet interactions
D. Revilla, P. J. Amado, R. Luque +17
Theory predicts that a planet with a sufficiently strong magnetic field orbiting close to its host star could induce star-planet magnetic interactions. This is potentially observab…
Mass determination of the ultra-short-period planet LHS 3844 b. First K-band radial velocity measurements with CRIRES+
E. Nagel, J. Köhler, M. Zechmeister +21
We present the first planet mass measurement obtained with CRIRES+ radial velocity (RV) observations using the K-band gas cell. Our target, LHS 3844 b (TOI-136), is a transiting su…
