About 6% of white dwarfs show infrared excess due to a disk around a white dwarf. [69] In the past only a relative small sample of white dwarf disks was known. [70] Due to advances in white dwarf detection (e.g. with Gaia or LAMOST) and improvement of WISE infrared catalogs with unWISE/CatWISE, the number has increased to hundreds of candidates.
Steve Jackson and Ian Livingstone initially produced a newsletter called Owl and Weasel, which ran for twenty-five issues from February 1975 before it evolved into White Dwarf. [1] Originally scheduled for May/June 1977, [2] White Dwarf was first published one month later. According to Shannon Appelcline, "Issue #1 ... was a 20-page magazine ...

The white dwarf existed for 10.21 ±0.22 Gyrs, meaning the total age is 10.7 ±0.3 Gyrs. [1] Cold white dwarfs are often strongly affected by collision induced absorption (CIA) of hydrogen. This can lead to faint optical red and infrared brightness. These white dwarfs are also called IR-faint white dwarfs. WD J2147–4035 is however very red (r ...
Owl and Weasel #6: Dungeons & Dragons special issue. The sixth issue, a key point in Games Workshop's early history, was released as a Dungeons & Dragons special – a first in the UK – and issues #11 and #23 doubled as programmes for their early Games Days, leading to coverage in The Times of these events and of their magazine.

WD 0816–310 (PM J08186–3110) is a magnetic white dwarf with metal pollution, originating from the tidal disruption of a planetary body. The metals are guided by the magnetic field onto the surface of the white dwarf, creating a "scar" on the surface of the white dwarf.
The bulk of the material in the first edition came from the British gaming magazine White Dwarf, rather than being authored by Gary Gygax, the game's co-creator. Readers and gamers had submitted creatures to the "Fiend Factory" department of the magazine, and the most highly regarded of those appearing in the first thirteen issues were selected ...
In the August 1984 edition of White Dwarf (Issue #56), Simon Farrell noted that in the first three issues of Encyclopedia Hârnica, the editors invited feedback and ideas for future articles from subscribers; Farrell speculated that, given the monthly nature of the periodical, if this feedback was quickly used to create articles for a four-week turnaround, "we can expect to see a decline in ...
