A Topological Study of Contextuality and Modality in Quantum Mechanics
Graciela Domenech, Hector Freytes, Christian de Ronde
Kochen-Specker theorem rules out the non-contextual assignment of values to physical magnitudes. Here we enrich the usual orthomodular structure of quantum mechanical propositions…
Discovery of magnetic fields in three He variable Bp stars with He and Si spots
M. Briquet, S. Hubrig, M. Schoeller +1
It is essential for the understanding of stellar structure models of high mass stars to explain why constant stars, non-pulsating chemically peculiar hot Bp stars and pulsating sta…
Early-type stars in the young open cluster IC1805. II. The probably single stars HD15570 and HD15629, and the massive binary/triple system HD15558
M. De Becker, G. Rauw, J. Manfroid +1
Aims: We address the issue of the multiplicity of the three brightest early-type stars of the young open cluster IC1805, namely HD15570, HD15629 and HD15558. Methods: For the three…
The HI content of E+A galaxies
P. Buyle, D. Michielsen, S. De Rijcke +3
We present deep single-dish HI observations of a sample of six nearby E+A galaxies (0.05<z<0.1). A non-negligible fraction of a local sample of E+As are detected in HI. In four gal…
