Discussion Overview

The discussion centers on the origins of our solar system, specifically the remnants of the star or stars that contributed to its formation. Participants explore the implications of supernovae, the migration of stellar remnants, and the generational history of stars leading to the Sun's birth.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that the solar system formed from the remnants of a supernova, questioning the location of the star's remnants, such as a neutron star or black hole.
  • Another participant argues that elements heavier than iron were created in supernovae early in the galaxy's formation, indicating that the material was likely reused in earlier generations of stars before the Sun formed.
  • It is proposed that the Sun was born in a gas cloud with many other stars, which were scattered into different orbits due to gravitational interactions over billions of years.
  • Questions are raised about the speed of the Sun's travel and the reference points for measuring this speed.
  • A participant humorously states that scientifically, the Sun has no "mother" and questions the notion of a single progenitor star.
  • Another participant mentions that several generations of stars, including pop-III and II stars, contributed to the Sun's formation, with many remnants dispersed or absorbed by a central black hole.
  • It is noted that after billions of years, the remnants of the Sun's progenitor could be located almost anywhere in or outside the galaxy, emphasizing that no single star provided all materials for the solar system.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the origins of the solar system and the nature of its progenitor stars. There is no consensus on the specifics of the progenitor star or its remnants.

Contextual Notes

Participants acknowledge the complexity of stellar evolution and the potential for multiple generations of stars contributing to the solar system's formation, but do not resolve the uncertainties regarding specific progenitor stars or their remnants.

We know our solar system had to have been formed at least partially from the remnants of a supernova, due to the abundance of heavy elements on Earth and elsewhere. My question is, where is corpse of the star which gave birth to us?

There should be a neutron star, or even a black hole, that is left behind from whatever star blew up over 6 billion years ago that we formed from, but the question is where? How far could such a star have migrated since that time from the current position of the sun, or is it likely that the sun is no where near the location of the actual star which blew up?

Elements heavier than iron were created in a supernova but that would have been very early in the formation of the galaxy - the material would have been reused through an earlier generation of stars before our sun formed.

There isn't a specific progenitor supernova
 
The Sun was probably born in a cloud of gas along with dozens to hundreds of other stars.

Due to gravitational interaction it is thought that the stars would have been scattered into different orbits around galactic center. That was 5 billion years ago more or less. The sun orbits galactic center every 200-250 million years. So Sol has completed some 20 to 25 orbits since its birth. We are probably far from where first ignition occurred.
 
200-250 millions years. How fast are we travelling, or do we not have a reference point to give it a speed?

About 25,000 lyr from the centre and 225M yr to go around.

The title of this topic is "Where is the Sun's mother?" Scientifically speaking, the Sun has no mother and there is no 'corpse of the star which gave birth to us'.:smile: Thank you.
 
There are several generations of pop-III and II stars that were ancestors of the sun, most of them are either completely dispersed into current pop-I stars or absorbed into the black hole at the center.
 
After over many billions of years, the suns progenitor remnants could be almost anywhere in, or outside, our galaxy. It is virtually certain no single star provided all the raw materials from which our solar system formed. In other words, what mgb said.
