Experimental Observation of Short-Range Magnetic Correlations in Amorphous NbO and TaO Thin Films
Y. V. Krasnikova, A. A. Murthy, D. Bafia +17
We use muon spin rotation/relaxation/resonance (SR) to investigate the magnetic properties of niobium pentoxide (NbO) and tantalum pentoxide (TaO) thin films. I…
CORALIE radial-velocity search for companions around evolved stars (CASCADES) IV: New planetary systems around HD 87816, HD 94890, and HD 102888 and an update on HD 121056
E. Fontanet, S. Udry, D. Ségransan +25
With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains limited.…
RISTRETTO: the PIAA Nuller in the prototyping phase
N. Restori, N. Blind, J. Kühn +6
The objective of the coronagraphic IFU of RISTRETTO is to enable High Dispersion Coronagraphy of planets at a distance of 2/D from their star, without compromising on transmiss…
RISTRETTO: a VLT XAO design to reach Proxima Cen b in the visible
N. Blind, M. Shinde, I. Dinis +10
RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO \cite{lovis_2016a}, aiming at High Dispersion Coronagraphy. RISTRETTO is a visit…
Exoplanets with ELT-METIS I: Estimating the direct imaging exoplanet yield around stars within 6.5 parsecs
Rory Bowens, Michael R. Meyer, C. Delacroix +9
Direct imaging is a powerful exoplanet discovery technique that is complementary to other techniques and offers great promise in the era of 30 meter class telescopes. Space-based t…
Three Hot Jupiters transiting K-dwarfs with a significant heavy element mass
Y. G. C. Frensch, F. Bouchy, G. Lo Curto +50
Albeit at a lower frequency than around hotter stars, short-period gas giants around low-mass stars ( K) do exist, despite predictions from planetary populat…
