Cold and eccentric: a high-spectral resolution view of 51 Eri b with VLT/HiRISE

A. Denis, A. Vigan, G. Chauvin +35

Discovered almost 10 years ago, the giant planet 51 Eridani b is one of the least separated (0.2 arcsec) and faintest (J = 19.74 mag) directly imaged exoplanets known to date. Its…

Characterization of AF Lep b at high spectral resolution with VLT/HiRISE

A. Denis, A. Vigan, J. Costes +41

Since the recent discovery of the directly imaged super-Jovian planet AF Lep b, several studies have been conducted to characterize its atmosphere and constrain its orbital paramet…

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…

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…

Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE

V. Hocdé, N. Nardetto, A. Matter +149

The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…

The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?

J. Varga, M. Hogerheijde, R. van Boekel +133

Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…

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…
