ENCYCLOPEDIA GALACTICA Edition 428193 - Earth English
Definition: 'Purple Dwarf'
A Purple or P-dwarf is a Language English1 scientific expression defining a special class of the substellar L-dwarf family - bodies formerly known as brown dwarfs in the old catalogues.2 The P-dwarf is distinctive from other L-dwarfs due to its rapid rotation and intense, complex magnetic field. Observed periods are as short as eleven (11) minutes for bodies from fifty (50) to seventy-five (75) Jovian masses. The strong angular momentum combined with a dwarf's metallic hydrogen composition generates a magnetic field as strong as 5x105 gauss.3 This field induces electric currents in the atmosphere that energize the composing atoms and generate a luminous blue4 halo of varying brightness. The halo, combined with a normal L-dwarf's red to infrared4 black body glow - radiation generated from internal heat and supplemented by a P-dwarf's strong magnetic flux - produces a shifting purple4 hue with an absolute magnitude from +14.8 to +15.6.
Although P-dwarfs and L-dwarfs do not fuse hydrogen or shine as stars, they do radiate strong levels of infrared radiation. Sufficient to create a narrow temperate zone5 that can centre from one-half (0.5) to two (2) million (106) km3 from the dwarf. In such regions metabolic supportive liquids6 such as water7 may be present on existing satellites if they have masses sufficient to retain a substantive atmosphere. For such temperate satellites, biospheres3 are possible but the close proximity to the dwarf will cause a satellite's rotational and orbital periods to synchronize.8 Usually, with one hemisphere always facing its energy source, a body may only develop a biosphere near hemispheric boundaries where the climate never becomes extreme and has measurable cycles. But, in the case of a P-dwarf system, radiation is not the only conduit for receiving available electromagnetic energy.
Energy can be imparted into a biosphere through magnetic induction. The same magnetic field which causes a P-dwarf's blue aura can transfer energy to other orbiting bodies. The influx of energy through induction compensates for lack of direct radiation on the far side of a satellite. Therefore a temperate satellite would receive energy from both infrared radiation and magnetic induction. This enables such a body to support both a photoconsumption ecology9 and an electromotive ecology.10 The crystallographic life forms native to such an ecology are classified as living metals.11 Molecular level examples of such life forms are colloquially described as naturally occurring nanites.12
P-drawfs should not be confused with the much cooler and lighter T-dwarf. T-dwarfs owe their similar hue to sodium and potassium absorption (which represses the yellow and green portions of the visible spectrum4) in the atmosphere.

Wowie, that's a lot of information-- thank you for sharing this with us. Hope to see more in the future!

Ooh, I love these things and the information you provide is really cool in that fictionalized real way that I love so much. The image is stirring and reminds me of the best stuff I saw on Carl Sagan's Cosmos, back in the day...all this really needs is music by Vangelis. The color is amazing and quite cosmic in all of the best ways. Now I look forward to the day when humans WILL be able to see stuff like this, live and in person! If we don't wipe ourselves out or smother in our own smog first! Really super work and I'm glad that I'm slowly beginning to catch up. This is really superb and I love the info...it's nicely informative and accessible and very, very knowledgeable.

Living metals, interesting concept!

great render! like the black horizon and the sudden appearence of the purple dwarf!

Great looking image and lots of info, excellent my friend.

Just wonderful! A keen vision and imagination at work here.

Living metals...yes, I'd definitely be spending time looking those up. Are any of them sentient? I love all the different ways you have described, that life can exist. Just imagine all the life out there for us to discover if we don't destroy our world and us with it first. Imagine communicating with a species that is so different that you can never have direct contact with them. Excellent image! I like all the sparkles on the land. Are they living metals? You've put great definition and depth to the landscape even though it's very dark. The color, patterns, and haze of the purple dwarf are beautiful.
