A White Dwarf Catalog from LAMOST DR11 Using Deep Learning
The Astrophysical Journal Supplement SeriesWhite dwarfs, also referred to as degenerate dwarfs, represent the ultimate fate for the majority of stars in the Universe, unless their mass is large enough for them to evolve into black holes or neutron stars.

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...

Mutual Validation of Data Sets for Analyzing Tilt Angles in Solar Active Regions
The Astrophysical JournalThe tilt angle of solar active regions (ARs) is crucial for the Babcock–Leighton-type dynamo models in the buildup of the polar field. However, divergent results regarding properties of tilt angles were reported due to their wide scatter, caused by ...

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...
