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…
First light of VLT/HiRISE: High-resolution spectroscopy of young giant exoplanets
A. Vigan, M. El Morsy, M. Lopez +46
A major endeavor of this decade is the direct characterization of young giant exoplanets at high spectral resolution to determine the composition of their atmosphere and infer thei…
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…
The Enhanced Resolution Imager and Spectrograph for the VLT
R. Davies, O. Absil, G. Agapito +81
ERIS, the Enhanced Resolution Imager and Spectrograph, is an instrument that both extends and enhances the fundamental diffraction limited imaging and spectroscopy capability for t…
CRIRES+ detection of CO emissions lines and temperature inversions on the dayside of WASP-18b and WASP-76b
F. Yan, L. Nortmann, A. Reiners +21
The dayside atmospheres of ultra-hot Jupiters (UHJs) are predicted to possess temperature inversion layers with extremely high temperatures at high altitudes. We observed the daysi…
CRIRES on sky at the ESO Very Large Telescope
R. J. Dorn, P. Bristow, J. V. Smoker +49
The CRyogenic InfraRed Echelle Spectrograph (CRIRES) Upgrade project CRIRES extended the capabilities of CRIRES. It transformed this VLT instrument into a cross-dispersed spe…
Connecting SPHERE and CRIRES+ for the characterisation of young exoplanets at high spectral resolution: status update of VLT/HiRISE
A. Vigan, M. Lopez, M. El Morsy +32
New generation exoplanet imagers on large ground-based telescopes are highly optimised for the detection of young giant exoplanets in the near-infrared, but they are intrinsically…
Direct characterization of young giant exoplanets at high spectral resolution by coupling SPHERE and CRIRES+
G. P. P. L. Otten, A. Vigan, E. Muslimov +19
Studies of atmospheres of directly imaged exoplanets with high-resolution spectrographs have shown that their characterization is predominantly limited by noise on the stellar halo…
NAOMI: the adaptive optics system of the Auxiliary Telescopes of the VLTI
Woillez J., Abad J. A., Abuter R. +80
The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmosph…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
Bringing high-spectral resolution to VLT/SPHERE with a fibre coupling to VLT/CRIRES+
A. Vigan, G. P. P. L. Otten, E. Muslimov +9
Atmospheric composition provides essential markers of the most fundamental properties of giant exoplanets, such as their formation mechanism or internal structure. New-generation e…
Concept and optical design of the cross-disperser module for CRIRES+
E. Oliva, A. Tozzi, D. Ferruzzi +31
CRIRES, the ESO high resolution infrared spectrometer, is a unique instrument which allows astronomers to access a parameter space which up to now was largely uncharted. In its cur…
ESPRESSO: The next European exoplanet hunter
F. Pepe, P. Molaro, S. Cristiani +55
The acronym ESPRESSO stems for Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations; this instrument will be the next VLT high resolution spectrograph. T…
