Ages of White Dwarf-Red Subdwarf Systems
, 2005 We provide the first age estimates for two recently discovered white dwarf-red subdwarf systems, LHS 193AB and LHS 300AB. These unusual systems provide a new opportunity for linking the reliable age estimates for the white dwarfs to the (measurable ...

Can the rapid braking of the white dwarf in AE Aquarii be explained in terms of the gravitational wave emitter mechanism? [PDF]
, 2002 The spin-down power of the white dwarf in the close binary AE Aquarii significantly exceeds the bolometric luminosity of the system. The interpretation of this phenomenon in terms of the gravitational-wave emitter mechanism has been recently suggested by

Relativistic deflection of background starlight measures the mass of a nearby white dwarf star [PDF]
Science, 2017 General relativity weighs a white dwarf Light from a background star is deflected by the gravitational field of the Sun. This effect was used in 1919 to provide some of the first evidence for general relativity. Sahu et al. applied the concept to another

Learning Crystallographic Disorder: Bridging Prediction and Experiment in Materials Discovery
Advanced Materials, EarlyView.Machine learning based computational materials discovery workflows have recently proposed thousands of potentially stable crystalline materials. However, the experimental realization of these predictions is often challenging because the models assume perfectly ordered structures.

Features of the mass transfer in magnetic cataclysmic variables with fast-rotating white dwarfs
EPJ Web of Conferences, 2014 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

Control of Covalent Bond Enables Efficient Magnetic Cooling
Advanced Materials, EarlyView.Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Spectroscopic confirmation of a white dwarf companion to the B star 16 Dra [PDF]
, 2000 Using an Extreme Ultraviolet Explorer (EUVE) spectrum, we confirm the identification of a white dwarf companion to the B9.5V star 16 Dra (HD150100), and constrain its surface temperature to lie between 29,000K and 35,000K.

Hot white dwarfs and the UV delay in dwarf novae
, 1998 We calculate the effect of illumination of dwarf nova accretion discs by radiation from a hot, central, white dwarf. We show that only for very hot white dwarfs (Teff ~ 40 000$ K) the inner region of quiescent dwarf nova discs are partially depleted so ...
