Advanced Photonics Research, EarlyView.The necessity and feasibility of enhancing light outcoupling in perovskite light‐emitting diodes (PeLEDs) is highlighted. On near‐IR PeLEDs, low‐cost, micro‐textured light management (LM) foils demonstrate boost in light extraction. Optimizing perovskite thickness and the optical cavity in synergy with LM foils is crucial for maximizing performance ...

A radio-pulsing white dwarf binary star [PDF]
Nature, 2016 White dwarfs are compact stars, similar in size to Earth but ~200,000 times more massive. Isolated white dwarfs emit most of their power from ultraviolet to near-infrared wavelengths, but when in close orbits with less dense stars, white dwarfs can strip material from their companions, and the resulting mass transfer can generate atomic line and X-ray ...

The Astronomical Journal, 2023 Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with Keck/MOSFIRE, Gemini/GNIRS, and Gemini/Flamingos-2 of seven white dwarfs ...

Magnetic white dwarf stars in the Sloan Digital Sky Survey [PDF]
, 2012 To obtain better statistics on the occurrence of magnetism among white dwarfs, we searched the spectra of the hydrogen atmosphere white dwarf stars (DAs) in the Data Release 7 of the Sloan Digital Sky Survey (SDSS) for Zeeman splittings and estimated the

Asteroseismology of white dwarf stars [PDF]
Highlights of Astronomy, 1995 Perhaps the hardest scientific problems to solve are those most scientists believe have already been solved, but which have not. Any model we make of an astronomical process is doomed to be incomplete at some level; the “broad-brush” picture of stellar structure and evolution is often accepted as a solved problem, but in fact many discrepancies exist ...
