Astronomers Confirm Primordial Variations Cause Differences in Binary Stars
Using the Gemini South telescope, scientists have for the first time traced differences in binary stars to variations in their primordial molecular clouds.
- Astronomers have discovered that binary stars, despite originating from the same molecular cloud, can have different chemical compositions and host diverse planetary systems.
- This finding challenges previous models of star and planet formation, suggesting a more complex process influenced by chemical non-uniformities in the clouds.
- The Gemini High-Resolution Optical Spectrograph (GHOST) provided the precise measurements necessary to identify these primordial differences.
- The study disproves earlier theories that differences arose from processes occurring after the stars had formed, such as atomic diffusion or planetary engulfment.
- These insights could alter how astronomers use chemical composition to trace stars' origins and impact our understanding of planetary system diversity.
