Mergers via failed common envelope as a route toward intermediate-mass stripped stars

open access: yesAstronomy & Astrophysics
Stripped 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.

CCD Photometry of the Open Cluster Tombaugh 5 in the Vilnius System

open access: yesOpen Astronomy, 2011
We present the results of eight-color CCD photometry of 674 stars in the direction of the open cluster Tombaugh 5 in Camelopardalis. The stars are observed in the Vilnius system supplemented by the broad-band I filter; the field is of 22’ diameter, the ...

Recent Advances in Light‐Addressable Electrochemistry for Spatially Resolved Applications

open access: yesAdvanced Materials Technologies, EarlyView.
This comprehensive review highlights light‐addressable electrochemistry as a powerful tool that uses light to control localized chemical reactions on unstructured semiconductor surfaces. The work evaluates advanced strategies to optimize electrode materials for enhanced spatial resolution and stability. Furthermore, it showcases diverse applications in

Human‐Scale Rotating Magnetic Field Delivery With Permanent Magnets Under Anatomic and Robotic Constraints

open access: yesAdvanced Robotics Research, EarlyView.
Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

A Search for Magnetically Active Binary Counterparts to Chandra X-Ray Sources in 47 Tucanae with HST Imaging

open access: yesThe Astrophysical Journal
Using Hubble Space Telescope (HST) imaging, we searched for candidate magnetically active binary (AB) counterparts to low-luminosity Chandra X-ray sources in the globular cluster 47 Tucanae (NGC 104). We consider the catalog of 300 Chandra sources within

A rotation-based census of blue lurker candidates in open clusters

open access: yesAstronomy & Astrophysics
Aims. We have compiled a list of blue lurker (BL) candidates in open clusters using the available rotation catalogs. Blue lurkers are rejuvenated main-sequence stars hidden among normal main-sequence stars on color-magnitude diagrams of star clusters. In

Modeling the radial distribution of blue stragglers in M3

open access: yesThe Astrophysical Journal, 1994
Recent surveys of the blue straggler (BS) population in the galactic globular cluster M3 (NGC 5272) give the first complete characterization of the number density of BSs as a function of radius over an entire globular cluster. The BSs in M3 are overabundant at large radii, and significantly underabundant at intermediate radii.
