Dynamical Signatures of Trumpler 19: A Statistical and Photometric Perspective

open access: yesThe Astrophysical Journal
We present a statistical approach to investigating the dynamical evolution of the old open cluster Trumpler 19. We identified 810 cluster members using an ensemble-based unsupervised machine learning method applied to Gaia Data Release 3 astrometric data.

Queer in Science, Technology, Engineering, and Mathematics: Following the Intersections of Queerness, Transness and Science Identities

open access: yesScience Education, EarlyView.
ABSTRACT This multiple case study explores the intersections of queerness/transness and science education through a combined framework of queer theory, intersectionality, the construct of figured worlds and science identity. The study uses a life‐history approach to characterize the trajectories of three purposefully selected queer individuals who are ...

The Blue Lurker WOCS 14020: A Long-period Post-common-envelope Binary in M67 Originating from a Merger in a Triple System

open access: yesThe Astrophysical Journal Letters
We present Hubble Space Telescope far-ultraviolet (FUV) spectra of a blue lurker–white dwarf (BL–WD) binary system in the 4 Gyr open cluster M67. We fit the FUV spectrum of the WD, determining it is a C/O WD with a mass of $0.7{2}_{-0.04}^{+0.05}$ M _ ...

Blue straggler formation at core collapse

open access: yes, 2016
Among the most striking feature of blue straggler stars (BSS) is the presence of multiple sequences of BSSs in the colour-magnitude diagrams (CMDs) of several globular clusters. It is often envisaged that such a multiple BSS sequence would arise due a recent core collapse of the host cluster, triggering a number of stellar collisions and binary mass ...

Trans‐reflective color filters with brilliant colors by integrating organic dyes with photonic crystals

open access: yesSmart Molecules, EarlyView.
A novel trans‐reflective color filter design achieves high color purity, >70% transmittance, and exceptional UV/thermal stability by integrating dye‐doped polysulfone with photonic crystals, enabling advanced dual‐mode displays. Abstract Color filters are essential components for optical modulation.

Wind Roche-lobe Overflow in Low-mass Binaries: Exploring the Origin of Rapidly Rotating Blue Lurkers

open access: yesThe Astrophysical Journal
Wind Roche-lobe overflow (WRLOF) is a mass-transfer mechanism proposed by Mohamed and Podsiadlowski for stellar binaries wherein the wind acceleration zone of the donor star exceeds its Roche-lobe radius, allowing stellar wind material to be transferred ...
