KMOS view of the Galactic Centre I. Young stars are centrally concentrated [PDF]
The Galactic centre hosts a crowded, dense nuclear star cluster with a half-light radius of 4 pc. Most of the stars in the Galactic centre are cool late-type stars, but there are also >100 hot early-type stars in the central parsec of the Milky Way ...

The first gravitational-wave source from the isolated evolution of two stars in the 40–100 solar mass range [PDF]
The merger of two massive (about 30 solar masses) black holes has been detected in gravitational waves. This discovery validates recent predictions that massive binary black holes would constitute the first detection. Previous calculations, however, have

The alignment is in their stars: on the spin-alignment of stars in star clusters [PDF]
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.

Bp stars in OrionOB1 association [PDF]
A total of 85 CP stars of various types are identified among 814 members of the Orion OB1 association. We selected 59 Bp stars, which account for 13.4% of the total number of B type stars in the association.

Masses, Radii, and the Equation of State of Neutron Stars [PDF]
We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing of radio pulsars in binaries in the past few years, leading ...

On stars and Steiner stars. II [PDF]
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

Health literacy as a challenge for health education
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.

A grid of MARCS model atmospheres for late-type stars. I. Methods and general properties [PDF]
Context. In analyses of stellar spectra and colours, and for the analysis of integrated light from galaxies, a homogeneous grid of model atmospheres of late-type stars and corresponding flux spectra is needed. Aims.

From hadrons to quarks in neutron stars: a review [PDF]
In recent years our understanding of neutron stars has advanced remarkably, thanks to research converging from many directions. The importance of understanding neutron star behavior and structure has been underlined by the recent direct detection of ...

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.
