Discussion Overview

The discussion revolves around the search for sister stars in our multi-stellar system using infrared telescopes. Participants explore the possibility of detecting these stars, which are theorized to have similar characteristics and may harbor life, by observing 'cold' Jupiters and analyzing the structure of the Oort Cloud.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that sister stars should be of similar mass and main sequence, potentially detectable through infrared telescopes by evaluating gas giants like 'cold' Jupiters.
  • Others argue that if sister stars exist within our Oort Cloud, it could indicate a distorted cloud structure typical of multiple star systems.
  • A later reply questions the presence of a companion star, noting that gravitational effects would significantly influence planetary orbits.
  • Some participants suggest that brown dwarfs could also be considered as members of the multi-stellar system within the Oort Cloud.
  • There is a proposal to conduct an all-infrared sky survey to gather data on gas giants in other star systems to understand the typicality of our own system.
  • One participant mentions the empirical possibility of a supernova among sister stars, indicating variability in their characteristics.
  • Another participant highlights the dynamic nature of the galaxy, suggesting that stars in the arms mix over time, which may affect the search for sister stars.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the existence and characteristics of sister stars, as well as the implications of their potential presence within the Oort Cloud. The discussion remains unresolved with no consensus reached.

Contextual Notes

There are limitations regarding the assumptions made about the mass and characteristics of sister stars, as well as the gravitational influences on planetary orbits. The discussion also reflects uncertainty about the empirical evidence for supernova occurrences among these stars.

Our multi-stellar system?

Most stars form in multiples. Where are our sister stars? All of such sisters should be of somewhat similar mass, main sequence, and hence not supernova material; perhaps harboring life, and even culture? Such sisters must not be so far off. Hence might they be detectable by looking for 'cold' Jupiters? Use an infrared telescope to evaluate the luminosity and size of such gas giants, and through comparison, see if any are close. Such star(s) should be much less than 1 light year, and hence within the Oort Cloud. Thus if such sister stars are within our Oort Cloud, it would seem then to be a distorted cloud, common to such multiple star systems.

Sorry to burst the bubble, but, no companion star. Gravitational effects would be very pronounced on planetary orbits.

Might a brown dwarf be a member of such considered multiplex for inside common Oort Cloud?

As Chronos stated, the gravitational effects would be very pronounced on planetary orbits.

Might one also include an all infrared sky survey, looking for gas giants in general of other star systems? Thus building up a data set, and hence ascertaining how typical our system might be.
 
Thank you Ich, was going to say that there was a story about that a while back in Sci-Am or NS.

The galaxy doesn't turn as a solid disc, it only has a rotational profile like one, the stars in the arms mix and jostle around over the timescales we're talking about.
 
Our multi-stellar system? updated

Most stars form in multiples. Where are our sister stars? All of such sisters should be of somewhat similar mass, main sequence; but empirically perhaps 1 supernova. Such sisters must not be so far off. Hence might they be detectable by looking for 'cold' Jupiters? Use a dedicated infrared telescope to evaluate the luminosity and size of such gas giants, and through comparison, see if any are close. Such star(s) should be much less than 1 light year away, and hence within the common Oort Cloud. Thus if such sister stars are within our Oort Cloud, would it seem then to be a distorted cloud, common to such multiple star systems? However such set of sister stars would have a center of mass, and in accordance with a central force, a spherical distributed common Oort cloud of cometary material. Hence overlapping gravitational fields for such set of sister stars. Also if terrestrials are detected, then perhaps spectroscopically look for the atmospheric oxygen signature of photosynthesis. Also perhaps radio attention might be of interest for such near by sister star systems.

Why are you repeating your starting point? The forum is about dialogue, not monologue.
