Nonlinear Optical Microscopy of Semiconductor–Metal Nanocavities
Three‐dimensional nonlinear optical microscopy is used to visualize GaAs–gold hybrid nanocavities. By carefully selecting the pump wavelength to position the harmonic generation at the nanopillar resonance, an enhanced contrast is observed in the nonlinear imaging.

Features of the mass transfer in magnetic cataclysmic variables with fast-rotating white dwarfs
The flow structure in magnetic cataclysmic variables was investigated taking into account the effects of strong magnetic field and fast rotation of the white dwarf. We modeled the AE Aqr system as a unique object that has the rotation period of the white

Eclipsing binary and white dwarf features associated with K2 target EPIC251248385 [PDF]
White dwarfs, remnants of Sun-like stars which have completed their evolution, are one of the most common types of stars in space. Despite this, very few white dwarfs have been observed in transiting or eclipsing systems, and only two planetary systems ...

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Gaseous Material Orbiting the Polluted, Dusty White Dwarf HE1349-2305 [PDF]
We present new spectroscopic observations of the polluted, dusty, helium-dominated atmosphere white dwarf star HE1349-2305. Optical spectroscopy reveals weak CaII infrared triplet emission indicating that metallic gas debris orbits and is accreted by the

The plant RING‐between‐RING (RBR)‐type E3 ligase, Ariadne‐like protein 8 (ARI8), ubiquitinates and degrades a viral movement protein, restricting virus spread. ARI8 also inhibits other triple gene block 1 (TGB1)‐containing viruses, revealing a broad‐spectrum antiviral role.

Studying the Radiation of a White Dwarf Star Falling onto a Black Hole
We investigate electromagnetic and gravitational radiation generated during the process of the tidal stripping of a white dwarf star circulating a black hole.

Testing White Dwarf Age Estimates Using Wide Double White Dwarf Binaries from Gaia EDR3
White dwarf (WD) stars evolve simply and predictably, making them reliable age indicators. However, self-consistent validation of the methods for determining WD total ages has yet to be widely performed.
