#wr124 — Public Fediverse posts

This study from 2012, using 24 µm data from Spitzer, revealed that the ionized gas of nebula M1-67 ejected by WR 124 is condensed in knots aligned in a preferred axis along the NE-SW direction, with “holes” along the perpendicular direction.

The sketch below illustrates the (proposed) structure as an inner region with bipolar or elliptical shape along the direction NE−SW surrounded by an external spherical bubble.

Wolf–Rayet stars are massive luminous hot stars that have lost their outer hydrogen and are fusing helium and heavier elements in the core.
WR 124:
Distance: 15,000 ly
Location: Milky Way Galaxy, in the constellation Sagittarius.
Discovered by : Paul W. Merrill in 1938.
Mass: 30x solar mass ☉; has shed 10☉ worth of material so far.
Nebula size: 6 ly
Temp: 44,700 K
Elements: 15% hydrogen, rest is mainly helium.
Age: just 8.6 Myr

This image of the Wolf-Rayet star WR 124 and Nebula M1-67 was released by the JWST team today at #SXSW. The image was taken using the NIRCam and MIRI instruments in June 2022.
The 2nd image was taken by Hubble in 1998 and re-processed in 2015 by @spacegeck.
The massive young hot star is expelling star-stuff at ~200 km/s into the surrounding nebula.
It will explode as a type Ib or Ic supernova in a few 100,000 years.
