The alignment is in their stars: on the spin-alignment of stars in star clusters [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2018 ABSTRACT We simulate star formation in two molecular clouds extracted from a larger disc-galaxy simulation with a spatial resolution of ∼0.1 pc, one exiting a spiral arm dominated by compression, and another in an inter-arm region more strongly affected by galactic shear.

Discrete Optimization, 2009 AbstractA Steiner star for a set P of n points in Rd connects an arbitrary point in Rd to all points of P, while a star connects one of the points in P to the remaining n−1 points of P. All connections are realized by straight line segments. Let the length of a graph be the total Euclidean length of its edges.

The European Physical Journal C, 2017 In recent years, a growing interest on the equilibrium of compact astrophysical objects like white dwarf and neutron stars has been manifested. In particular, various modifications due to Planck scale energy effects have been considered. In this paper we analyze the modification induced by Gravity's Rainbow on the equilibrium configurations described ...

Health literacy as a challenge for health education
SHS Web of Conferences, 2018 Scientific literature demonstrates a well-established correlation between education and health literacy; education and health outcomes; health literacy and health outcomes. Health literacy has a mediating role between education and health.

On stars and Steiner stars. II [PDF]
Proceedings of the Twentieth Annual ACM-SIAM Symposium on Discrete Algorithms, 2009 A {\em Steiner star} for a set $P$ of $n$ points in $\RR^d$ connects an arbitrary center point to all points of $P$, while a {\em star} connects a point $p\in P$ to the remaining $n-1$ points of $P$. All connections are realized by straight line segments. Fekete and Meijer showed that the minimum star is at most $\sqrt{2}$ times longer than the minimum

Star Product and Star Exponential [PDF]
, 2012 Here we extend the star products by means of complex symmetric matrices. In this way we obtain a family of star products. Next we consider the star exponentials with respect to these star products, and finally we obtain several interesting identities.

Journal of High Energy Physics, 2018 AbstractWe explore the possibility that (Bose-Einstein) condensation of scalar fields from string compactifications can lead to long-lived compact objects. Depending on the type of scalar fields we find different realisations of star-like and solitonic objects.

Origin of Star-to-Star Abundance Inhomogeneities in Star Clusters [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractThe mass reinserted by young stars of an emerging massive compact cluster shows a bimodal hydrodynamic behaviour. In the inner part of the cluster, it is thermally unstable, while in its outer parts it forms an out-blowing wind. The chemical homogeneity/inhomogeneity of low/high mass clusters demonstrates the relevance of this solution to the ...
