Finding Clues in Ruins of Ancient Dead Star With NASA’s Chandra
- Astronomers are using data from NASA’s Chandra X-ray Observatory to conduct 'supernova archaeology' on a star that self-destructed over a million years ago.
- The remnants of a star that exploded, now part of the system GRO J1655-40, reveal clues about its past.
- The system originally had two stars, with one undergoing a supernova explosion, forming a black hole that exists today.
- The black hole started pulling matter from its companion, emitting material into space through powerful winds.
- By analyzing X-ray data using Chandra, astronomers identified elements in the black hole's winds, revealing the star's past characteristics.
- This 'supernova archaeology' study provides insights into the properties of the star that exploded, aiding future investigations of double star system outbursts.
- The findings were published in The Astrophysical Journal in May 2024 by a team including researchers from NASA and Technion.
- The Chandra program is managed by NASA's Marshall Space Flight Center, with operations handled by the Chandra X-ray Center.
- The visual description includes an artist's illustration of a supernova explosion and a spectrum graph indicating X-ray brightness and wavelengths of elements detected.
