Blue straggler stars in Galactic open clusters and the effect of field star contamination [PDF]
, 2019 Context. We investigate the distribution of blue straggler stars in the field of three open star clusters. Aims. The main purpose is to highlight the crucial role played by general Galactic disk fore-/back-ground field stars, which are often located in ...

Gate‐Induced Critical Current Modulation in W–C Nanowires: The Role of Fabrication
Advanced Materials Technologies, EarlyView.Focused ion beam induced deposition (FIBID) enables precise control of superconducting W–C nanowire devices. Introducing a Ga+ focused ion beam (FIB) cleaning step reduces substrate damage and suppresses leakage currents, shifting gating thresholds to higher voltages.

The incidence of magnetism in blue and yellow straggler stars
Context. Our understanding of the generation of magnetic fields in intermediate-mass and massive OBA stars remains limited. Some theories have proposed that their magnetic fields could be a result of strong binary interactions, including stellar mergers.

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice
Advanced Materials Technologies, EarlyView.We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

Characterization of Blue and Yellow Straggler Stars of Berkeley 39
The Astronomical JournalWe characterize blue straggler stars (BSSs) and yellow straggler stars (YSSs) of the open cluster (OC) Berkeley 39 using multiwavelength observations including the Swift/Ultraviolet and Optical Telescope (UVOT). Our analysis also makes use of ultraviolet

Blue Straggler Stars in Old Open Clusters and the Kraft Break
The Astrophysical Journal LettersWe measure the projected rotational velocities ( $v\sin i$ ) of solar-like blue straggler stars (BSSs) in the old (≥4 Gyr) open clusters M67, NGC 188, and NGC 6791.
