Named SNR J0614-7251 and SNR J0624-6948, the newly discovered supernova remains are located on the outskirts of the large Magelanic Cloud, the largest milky white satellite galaxy.
In the center of the image, stars cluster into a large Magellan cloud, a bright, dark green candy floss colored haze. Scattered in the center of the image are about 50 small yellow crosses, some of which are almost overlapping as they are very close to each other. SNR J0624-6948 (orange, high image) and SNR J0614-7251 (blue, bottom image) are seen in the lower left quarter of the image. Image credits: Eckhard Slawik/ESA/Xmm-Newton/Sasaki et al. / F. Zangrandi.
“Supranovae are stellar explosions, caused by massive star core collapse, neutron stars or black holes (core collapsing supernovae), or by thermonuclear destruction of white nuclei in binary systems. Friedrich- “We are a scientist at the same time,” said Alexander-Universität Erlangen-Nürnberg and colleague Dr. Manami Sasaki.
“Supranovae are important for galaxy material cycles and the formation of next-generation stars. Shockwave produces supernova debris that heats environmental or interstellar media to ionize, sweeping and compressing the environment, and making the environment more environmentally friendly and compressing. Enrich it. With chemical elements.”
use ESA's XMM-Newton Spaceshipastronomers discovered two supernova remnants, SNR J0614-7251 and SNR J0624-6948, in the large Magellan cloud.
“The big and small Magellan clouds are the largest satellite galaxies in the Milky Way and the closest ones,” they said.
“The Magellan Cloud is also the only satellite galaxy in the Milky Way with current active star formation.”
“A large Magellan cloud at a small distance (49,600 Parsec), its morphology is almost a hassle disk, and its low foreground absorption provides a detailed laboratory ideal for the study of large samples of the remaining supernovae. Masu.”
“Proximity allows for spatially resolved spectroscopic studies of supernova debris, and precisely known distances allow for the analysis of the energetics of each supernova debris.”
“In addition, the rich data of wide-field multi-wavelength data available provides information about the environment in which these supernova debris evolves.”
XMM-Newton observed SNR J0614-7251 and SNR J0624-6948 with three different types of X-ray light.
They show the most common chemical elements in various parts of the debris.
The center of SNR J0614-7251 is primarily made up of iron, according to the team.
This clue allowed researchers to classify this remnant for the first time as a result of a type IA supernova.
“The discovery of supernova remnants on the outskirts of the large Magellan cloud confirms that stellar explosions occur outside the galaxy and allows us to study their shocks, stellar ejectors and environment,” they said. I said that.
“It will help us to better understand the evolution of the Magellan cloud and the history of interacting galaxies and their surrounding star formation.”
“We hope that new multi-wavelength investigations will reveal more supernova remnants around the Magellan cloud.”
“This new supernova remnants allows us to study the supernova explosions and the rest of the supernova evolution in low density and low metallic environments, and better serve to better the effects of metallicity on star formation and star evolution. I can understand it.”
result It will be displayed in the journal Astronomy and Astrophysics.
