description N76 Overview
N76 is a Wolf-Rayet nebula and H II region in the Small Magellanic Cloud, centered on the Wolf-Rayet binary system AB7. Its gas is ionized by the hot central stellar source, while stellar winds have produced a hot, relatively empty cavity inside the surrounding nebula. Astronomical studies model N76 as an approximately spherical region with low-density ionized gas and strong infrared emission lines, making it a useful case for examining massive stars in a low-metallicity galaxy.
help N76 FAQ
What is N76?
N76 is a Wolf-Rayet nebula and H II region in the Small Magellanic Cloud. It is centered on the Wolf-Rayet binary system AB7.
What powers the nebula N76?
The gas is ionized by the hot central stellar source associated with AB7. Strong stellar winds have also shaped a hot, relatively empty cavity inside the surrounding nebula.
Where is N76 located?
N76 is located in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. Its central source is the Wolf-Rayet binary AB7.
Why does N76 have a cavity?
Stellar winds from the hot central system have swept material away from the interior. This creates a hot, relatively empty cavity surrounded by ionized nebular gas.
