Excitation of ion-acoustic waves by non-linear finite-amplitude standing Alfvén waves
Jaume Terradas, Adolfo F. - Viñas, Jaime A. Araneda
We investigate, using a multi-fluid approach, the main properties of standing ion-acoustic modes driven by nonlinear standing Alfvén waves. The standing character of the Alfvénic p…
An absolute calibration of the near-infrared Period-Luminosity Relations of Type II Cepheids in the Milky Way and in the Large Magellanic Cloud
Piotr Wielgórski, Grzegorz Pietrzyński, Bogumił Pilecki +29
We present time-series photometry of 21 nearby Type II Cepheids in the near-infrared J, H and Ks passbands. We use this photometry, together with the Third Gaia Early Data Release…
Enhanced discrimination of high-dimensional quantum states by concatenated optimal measurement strategies
M. A. Solís-Prosser, O. Jiménez, A. Delgado +1
The impossibility of deterministic and error-free discrimination among nonorthogonal quantum states lies at the core of quantum theory and constitutes a primitive for secure quantu…
ALMA-IMF I -- Investigating the origin of stellar masses: Introduction to the Large Program and first results
F. Motte, S. Bontemps, T. Csengeri +61
The ALMA-IMF Large Program imaged a total noncontiguous area of 53pc2, covering 15 extreme, nearby protoclusters of the Milky Way. They were selected to span relevant early protocl…
Exploring the s-process history in the Galactic disk: Cerium abundances and gradients in Open Clusters from the OCCAM/APOGEE sample
J. V. Sales-Silva, S. Daflon, K. Cunha +21
The APOGEE Open Cluster Chemical Abundances and Mapping (OCCAM) survey is used to probe the chemical evolution of the s-process element cerium in the Galactic disk. Cerium abundanc…
Interferometric detections of sdO companions orbiting three classical Be stars
R. Klement, G. H. Schaefer, D. R. Gies +17
Classical Be stars are possible products of close binary evolution, in which the mass donor becomes a hot, stripped O or B-type subdwarf (sdO/sdB), and the mass gainer spins up and…
