Those remnants went into orbit around the white dwarf — much like the rings around Saturn, Zuckerman said — before eventually spiraling onto the star itself, bringing with them the building blocks for life.

The scientists report that a minor planet in the planetary system was orbiting around the white dwarf, and its trajectory was somehow altered, perhaps by the gravitational pull of a planet in the same system.

The researchers found that relatively cool accretion discs around young stars, whose inner edges can be several times the size of the Sun, show the same behaviour as the hot, violent accretion discs around planet - sized white dwarfs, city - sized black holes and supermassive black holes as large as the entire Solar system, supporting the universality of accretion physics.

Named PH1, the planet goes around two of the four stars, shown close - up here: One is a yellow - white F - type star that is slightly warmer and more luminous than our sun; the other, at the 11 o'clock position, is a red dwarf, cooler and dimmer than the sun.

The detected water most likely came from a minor planet, at least 90 km in diameter but probably much larger, that once orbited the GD 61 star before it became a white dwarf around 200 million years ago.

As Vega is so much bigger and hotter than Sol, however, the star will exhaust its core hydrogen after only another 650 million years or so (for a total life of around a billion years) and turn into a red giant or Cepheid variable before puffing away its outer layers to reveal a remnant core as a white dwarf.

HD 147513 A is a so - called young «Barium dwarf» (s - process element rich but comparatively carbon deficient) star that was probably enriched by an asymptotic branch giant (AGB) star (see Gacrux) but is now a very dim, white dwarf companion, which has an observed separation of around 4,400 AUs — 5.7» at a HIPPARCOS distance estimate of 42.0 ly (Porto de Mello and da Silva, 1997; and Poveda et al, 1993, pp. 74 - 75).
