Summary
DescriptionALMA views a stellar explosion in Orion (labeled).jpg |
English: Stellar explosions are most often associated with supernovae, the spectacular deaths of stars. But new ALMA observations of the Orion Nebula complex provide insights into explosions at the other end of the stellar life cycle, star birth. Astronomers captured these dramatic images of the remains of a 500-year-old explosion as they explored the firework-like debris from the birth of a group of massive stars, demonstrating that star formation can be a violent and explosive process too. The colours in the ALMA data represent the relative Doppler shifting of the millimetre-wavelength light emitted by carbon monoxide gas. The blue colour in the ALMA data represents gas approaching at the highest speeds; the red colour is from gas moving toward us more slowly. The background image includes optical and near-infrared imaging from both the Gemini South and ESO Very Large Telescope. The famous Trapezium Cluster of hot young stars appears towards the bottom of this image. The ALMA data do not cover the full image shown here.
I adapted the different labels from the figures in Bally et al. 2017 (https://ui.adsabs.harvard.edu/abs/2017ApJ...837...60B/abstract). This image shows the explosion in Orion that likely ejected the stars Becklin–Neugebauer Object (BN, red circle), source I (blue circle) and source n (green circle). The measured motion of these stars are shown with arrows. Additionally the position of IRc 4 is shown, which might also have been ejected in the explosion. The position of two bubbles and the Source I outflow are also shown. |
