Discussion Overview

The discussion centers around the potential for the star systems Procyon and Capella to produce Type Ia supernovae. Participants explore the characteristics of these binary systems and the conditions required for such supernova events, considering both theoretical and observational aspects.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether Procyon or Capella could produce a Type Ia supernova.
  • Another participant asserts that only binary systems can generate Type Ia supernovae.
  • A participant references information from Wikipedia about Procyon A and B, noting their binary nature and the distance between them, suggesting that Procyon A might influence Procyon B when it evolves into a red giant.
  • One participant expresses the opinion that the stars are too far apart to generate a Type Ia supernova event in the foreseeable future.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether Procyon or Capella could produce a Type Ia supernova, with differing views on the implications of their binary nature and separation distance.

Contextual Notes

There are limitations regarding the assumptions about the evolutionary paths of the stars and the specific conditions required for a Type Ia supernova, which remain unresolved in the discussion.

would star systems such as Procyon or Capella blow up as 1a supernovae?
 
Astronomy news on Phys.org
Only binary systems can generate Ia supernova.
 
the reason i asked is because it says on wikipedia:

"What appears as a single star to the naked eye is actually a binary star system, consisting of a white main sequence star of spectral type F5 IV-V, named Procyon A, and a faint white dwarf companion of spectral type DA, named Procyon B. The reason for its brightness is not its intrinsic luminosity but its closeness to the Sun; at a distance of 3.5 pc or 11.41 light years..."

"The average separation of the two suns is 15 AUs, a little less than the distance between Uranus and the Sun, though the eccentric orbit carries them as close as 9 AUs and as far as 21"

so I'm wondering if procyon A will cause procyon B to explode when it turns into a red giant in 10-100 million years
-procyon B(white dwarf) is only .6 solar masses

here's A and B's orbit path http://en.wikipedia.org/wiki/Image:Procyonorbitillustration.JPG

Much too far apart to generate an SnIa event in the foreseeable future, IMO.
