Aims. We aim to study the structure of the nebula around the post-AGB, binary star 89 Her. The presence of a rotating disk around this star had been proposed but not been yet confirmed by observations. Methods. We present high-resolution PdBI maps of CO J=2–1 and 1–0. Properties of the nebula are directly derived from the data and model fitting. We also present N-band interferometric data on th...

We offered four annual professional development workshops called STAR (for Scientific Teaching, Assessment, and Resources) modeled after the National Academies Summer Institute (SI) on Undergraduate Education in Biology. In contrast to the SI focus on training faculty from research universities, STAR's target was faculty from community colleges, 2-yr campuses, and public and private research un...

In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.

We present Spitzer observations of the blue compact dwarf galaxy (BCD) Haro 3, with an oxygen abundance of 12+log(O/H)=8.32. These data are part of a larger study of star formation and dust in low-metallicity environments. The IRS spectrum of Haro 3 shows strong narrow Polycyclic Aromatic Hydrocarbon (PAH) emission, with high equivalent widths. Gaseous nebular fine-structure lines are also seen...

We consider a nonlinear finite volume (FV) scheme for stationary diffusion equation. We prove that the scheme is monotone, i.e. it preserves positivity of analytical solutions on arbitrary triangular meshes for strongly anisotropic and heterogeneous full tensor coefficients. The scheme is extended to regular star-shaped polygonal meshes and isotropic heterogeneous coefficients.

We develop Stone-Kleene relation algebras, which expand Stone relation algebras with a Kleene star operation to describe reachability in graphs. We show that finite matrices over extended real numbers form an instance. These theories are being prepared for the Archive of Formal Proofs. Further documentation will be added.

We study isotropic and slowly-rotating stars made of dark energy adopting the extended Chaplygin equation-of-state. compute moment inertia as a function mass stars, both for rotating non-rotating objects. The solution non-diagonal metric component radial coordinate three different star masses is shown well. find that (i) increases with star, (ii) in case objects grows faster, (iii) curve corres...

Objective PCOS is the most frequent female endocrine disorder, affecting 5%-10% of women, is characterized by hyperandrogenism, oligo-/anovulation, and polycystic ovaries. The aim of the present research is to evaluate the expression of steroidogenic acute regulatory protein (StAR) and CYP19 (aromatase) mRNA in the ovary of EV-induced PCOS rat model and the effect of the treadmill and running w...
