Recent Results from Infrared Observations of White Dwarfs, their Companions, and the Dust that Surrounds Them [PDF]
, 2007 Although "traditionally" observed at short wavelengths, white dwarfs have displayed many surprising features when probed in the infrared. We present an overview of recent results from ground- and space-based near- to mid-infrared observations of white ...

An Exploration of Spotted White Dwarfs from K2 [PDF]
, 2018 The 21st European Workshop on White Dwarfs was held in Austin, TX from July 23rd to 27th of 2018The Kepler K2 mission has discovered a significant population of white dwarf stars that exhibit photometric variability due to surface inhomogeneities ...

Explosion of White Dwarfs [PDF]
International Astronomical Union Colloquium, 1987 AbstractWe present models for Type I supernova light curves based on the explosion of partially solid white dwarfs in close binary systems. Studies of such explosions show that they leave bound remnants of different size. Our results reproduce quite well the maximun luminosities, the expansion velocities and the shape of the light curve.

Alzheimer's Disease Risk Factor APOE4 Exerts Dimorphic Effects on Female Bone
Advanced Science, EarlyView.In aging bone, osteocytes accumulate neurodegenerative risk factor Apolipoprotein E (APOE). A humanized version of the Alzheimer's disease risk allele APOE4 altered the mouse bone transcriptome and proteome, with effects in female bone surpassing the brain, including bone fragility due to suppressed osteocytic maintenance of bone quality, identifying ...

The Astrophysical JournalWe increase the spectroscopic completeness of the 100 pc white dwarf sample in the Sloan Digital Sky Survey footprint with 840 additional spectra. Our spectroscopy is 86% complete for white dwarfs hotter than T _eff = 5000 K, where H α remains visible ...

The Pan-STARRS1 Planet Survey: Overview and first results
EPJ Web of Conferences, 2013 The Pan-STARRS1 Planet Survey (Pan-Planets) is a search for transiting extra-solar planets in the Galactic disk with a focus on planets around M-dwarfs and White dwarfs.

Symposium - International Astronomical Union, 1974 The effects of core crystallization and of convection in the envelope on the cooling of white dwarfs are reviewed. The case of a 0.6 M⊙ white dwarf composed of an oxygen core and a helium envelope is taken as example. Also the amount of hydrogen that a white dwarf can accrete before nuclear burning occurs is estimated and possible evolutionary ...

Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants
Advanced Science, EarlyView.The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

The Origins of Lithium Enhancement in Polluted White Dwarfs
The Astrophysical JournalThe bulk abundances of exoplanetesimals can be measured when they are accreted by white dwarfs. Recently, lithium from the accretion of exoplanetesimals was detected in relatively high levels in multiple white dwarfs.
