UOCS-XIX. A Multiwavelength Study of Open Cluster Trumpler 5: Cluster Properties and Exotic Populations

open access: yesThe Astronomical Journal
Trumpler 5 is a populous, intermediate-age (∼3 Gyr), metal-poor ([Fe/H] ∼ −0.4) open cluster, located at a distance of approximately ∼3050 pc. This is a well-studied cluster for its broadened main-sequence (MS) and blue straggler star (BSS) population ...

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

open access: yesStructural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

The Impact of Stellar Rotations and Binaries on the Shape of Upper Main Sequence near Turnoff in Open Cluster NGC 6067

open access: yesThe Astrophysical Journal
We present the analysis of the extended main-sequence turnoff (eMSTO) in the open cluster NGC 6067. We derive the projected rotational velocity, v sin i , of the stars belonging to the eMSTO region of the main sequence (MS) utilizing Gaia-ESO spectra ...

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

open access: yesWildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Binary Fraction in Galactic Star Clusters: FSR 866, NGC 1960, and STOCK 2

open access: yesThe Astronomical Journal
The study of binary stars in different astronomical environments offers insights into the dynamical state of the hosting stellar systems. The binary fraction in fact plays a crucial role in the dynamical evolution of stellar systems, regulating processes

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...
