The Strange Case Of 2019yvr Supernova



In a recent study, a team of astronomers led by Northwestern University describes the characteristics of a supernova that exploded in 2019 and its progenitor star, a yellow supergiant, observed two and a half years apart. The results show a discrepancy in the hydrogen content that leads to a re-evaluation of what is possible during the end of life of the most massive stars.

The Danish astronomer Tycho Brahe, that in 1572 was among those who noticed a new bright object in the constellation Cassiopeia. 
Adding fuel to the intellectual fire that Copernicus started, Tycho showed this “new star” was far beyond the Moon, and that it was possible for the universe beyond the Sun and planets to change.
Astronomers now know that Tycho’s new star was not new at all. Rather it signalled the death of a star in a supernova, an explosion so bright that it can outshine the light from an entire galaxy. This particular supernova was a Type Ia, which occurs when a white dwarf star pulls material from or merges with, a nearby companion star until an explosion is triggered. The white dwarf star is obliterated, sending its debris hurtling into space.
In its two decades of operation, NASA’s Chandra X-ray Observatory has captured unparalleled X-ray images of many supernova remnants, and of course it took a look at Tycho.
Chandra telescope revealed an intriguing pattern of bright clumps and fainter areas in Tycho’s Supernova.
Here you can see Tycho’s supernova as seen by Chandra.
