Research Reveals the Temporal Evolution of Gamm... (2025-10-17)
For the first time, evolving gamma-ray emission lines were detected in GRB 221009A. Researchers propose a down-Comptonization model, where line photons lose energy by scattering in a dense medium, ...
NVST Captures Detailed Physics of Chromospheric... (2025-10-17)
High-resolution NVST observations reveal the physical properties and transverse oscillations of chromospheric fibrils. These kink waves carry an energy flux insufficient for chromospheric heating, ...
Researchers Investigate the Binary Fraction of ... (2025-10-14)
A Yunnan Observatories team published a study in Astronomy & Astrophysics on Blue Horizontal-branch (BHB) stars’ binary fraction via LAMOST data. It found BHB’s intrinsic binary fraction is ~32%,...
