The Distribution of Blue Straggler Stars in the Color–Magnitude Diagrams of Old Open Clusters
The Astronomical JournalWe examine the blue straggler star (BSS) populations of six old (≥4 Gyr) open clusters: M67, NGC 188, NGC 6791, Berkeley 32, Berkeley 39, and Trumpler 19.

New parameters for star-cluster dynamics: Observational results
Astronomy & AstrophysicsWe recently used a large set of Monte Carlo simulations of globular clusters (GCs) to define new, fully empirical parameters (named A51, P51, and S2.5) able to trace the internal dynamical evolution of dense stellar systems.

Stellar Collisions and Blue Straggler Formation
, 2001 We review recent 3D hydrodynamic calculations of stellar collisions using the Smoothed Particle Hydrodynamics (SPH) method, and we discuss the implications of the results for the formation and evolution of blue stragglers in globular clusters. We also discuss the construction of simple analytic models for merger remnants, approximating the mass loss ...

The Journal of Wildlife Management, EarlyView.When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network
Laser &Photonics Reviews, EarlyView.This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Mergers via failed common envelope as a route toward intermediate-mass stripped stars
Astronomy & AstrophysicsStripped stars are a common product of binary stellar systems, spanning a wide mass range from Wolf-Rayet stars to hot subdwarfs and helium white dwarfs.

Nonprofit Management and Leadership, EarlyView.ABSTRACT The purpose of this paper is to develop foundational propositions designed to reflect success factors in the recruitment and retention of volunteers for future longevity. Using insights gathered from three universities' experiences of student volunteering during COVID‐19, plus capturing the experiences of volunteer involving organizations, we ...

The Astrophysical JournalBlue horizontal branch stars (BHBs), excellent distant tracers for probing the Milky Way’s halo density profile, are distinguished in the ${\left(g-r\right)}_{0}$ versus ( i − z ) _0 color space from another class of stars, blue straggler stars.
