Combined General Catalogue of Variable Stars.
The model under consideration is the two-dimensional (2D) one-componentplasma of pointlike charged particles in a uniform neutralizingbackground, interacting through the logarithmic Coulomb interaction.Classical equilibrium statistical mechanics is studied bynon-traditional means. The question of the potential integrability(exact solvability) of the plasma is investigated, first at arbitrarycoupling constant \Gamma via an equivalent 2D Euclidean-field theory,and then at the specific values of \Gamma=2*integer via an equivalent 1Dfermionic model. The answer to the question in the title is that thereis strong evidence for the model being not exactly solvable at arbitrary\Gamma but becoming exactly solvable at \Gamma=2*integer. As aby-product of the developed formalism, the gauge invariance of theplasma is proven at the free-fermion point \Gamma=2; the relatedmathematical peculiarity is the exact inversion of a class ofinfinite-dimensional matrices.
| A homogeneous catalog of new UBV and H-beta photometry of B- and A-type stars in and around the Scorpius-Centaurus OB association
B- and A-type stars in and near the Sco-Cen OB association areinvestigated with UBV and H-beta photometry to acquire data relevant tothe luminosity function of Sco-Cen. The measurements generally consistof two 10-s integrations of U, B, V, (W, N) filters, and theobservations are corrected iteratively for atmospheric extinction andinstrumental response. The data presented give the mean V magnitude,mean B-V, mean U-B, and the estimated uncertainties for these values.The catalog provides a homogeneous catalog of data for a large fieldwith stellar objects delineating membership to the association Sco-Cenand that affect the luminosity function of the aggregate.
| Walraven photometry of nearby southern OB associations
Homogeneous Walraven (VBLUW) photometry is presented for 5260 stars inthe regions of five nearby southern OB associations: Scorpio Centaurus(Sco OB2), Orion OB1, Canis Major OB1, Monoceros OB1, and Scutum OB2.Derived V and (B - V) in the Johnson system are included.
