• Inhabited white dwarf systems in SF?

    From Tony Nance@3:633/10 to All on Monday, January 19, 2026 11:09:46

    Have there been SF works that had life (inhabited planets/moons) in
    white dwarf systems? I'm thinking "surely there have been - probably
    several", but I can't think of any.

    Systems that _only_ have white dwarfs or systems that have in addition
    to main sequence stars one or more white dwarfs?

    I was thinking the former, but would also be happy with the latter.

    Any novel featuring either Sirius or Procyon. For example, Bova's
    1972 As On a Darkling Plain, where Sirius B being a white dwarf
    (or how it became one) is relevent to the plot.

    Ah, yes - thanks. Not that I've read the Bova, but the two stars you

    So now I guess I'm thinking more about the former.

    Being in the same system as a white dwarf probably means any formerly
    habitable planet had its atmosphere blow-torched off. Not an issue
    for either Sirius or Procyon, as the stellar orbits preclude habitable
    planets.

    Now, 40 Eridani is an interesing case where a sunlike star is orbited at
    a fair distance by a red dwarf and a white dwarf. It may be that any
    Earthlike world around A was only badly damaged. Fodder for an Andre Norton-style death world.

    His last novel, iirc.

    Multiple sources agree, although he did write his autobiography/memoir

    Re: "habitable": That's part of what inspired the question. With all the different types of life in SF, are there settings where someone put life
    in a white dwarf system? For example, we have seen authors write about
    native silicon-based life, native life in the atmospheres of gas giants,
    etc.

    Great stories about life on the surface of neutron stars.
    very two dimensional but making the best of a high gravitation
    and communicating with the homo sapiens off in the distance.

    But just because the atmosphere a planet had is blown away
    does not mean that it cannot be replaced and then we have domed
    cities as well in SF.

    bliss

    In the Larry Niven story, "One Face" a hyperjump to sol goes badly wrong
    and the ship jumps to the far future, in sun's white dwarf stage, with
    earth a frozen and tidally locked planet.

    Somehow they concoct a plan to start the earth spinning again, and plan
    to farm it when this is done.

    In Karl Schroeder's "Permanence" people using STL largely settle on
    worlds of brown dwarfs, the assumption in this book being that such
    dwarfs are far more common than luminous stars, hence shorter distances
    and travel times between them. These worlds do tend to be a tad dark and chilly, though.

    Jack Vance has one of his villains living on a "dead" star. How he
    handwaves away the gravity I do not recall.

    Clarke commented somewhere on the story possibilities of white dwarfs,
    which will radiate strongly for trillions of years, but I don't recall
    his ever using that in his own work.

    Not really. The writers simply put habitable planets around any
    type of star they have heard of. They also have the occasional
    green or purple star. Because pretty.

    Dwarf stars, being small, would have a ?Goldilocks zone? (for
    Earth-type life, anyway) very close in, leading to tidally-locked
    planets, if you wanted livable ones.

    However, it occurs to me that moons of those planets would be in the
    same Goldilocks zone, and being tidally locked (if at all) to their
    primary planet rather than the star, would enjoy the
    temperature-moderating effects of day/night cycles to some degree.

    If the planet were a giant planet, it could even have a decent-sized
    moon, with sufficient gravity to hold on to a usable atmosphere.

    I said habitable planets around Sirius or Procyon can't exist for orbital dynamics reasons but I should have added "A" to both. Potentially
    habitable planets could exist around the white dwarfs without the
    other star perturbing them out of orbit.

    They'd be very young and you'd have to terraform them. Also, their
    orbital velocities around the white dwarfs would be very high,
    and the Ek of impactors scales as V^2.

    Any novel featuring either Sirius or Procyon. For example, Bova's
    1972 As On a Darkling Plain, where Sirius B being a white dwarf (or
    how it became one) is relevent to the plot.

    Sirius is young. How young?

    When multicellular life appeared on Earth, there was no Sirius in the
    sky.

    Being in the same system as a white dwarf probably means any

    Could the same blowtorch reduce a former gas giant into a smaller,
    rockier, more habitable core?
