Y. Grosdidier et al., Hst wfpc2h alpha imagery of the nebula M1-67: A clumpy LBV wind imprintingitself on the nebular structure?, ASTROPHYS J, 506(2), 1998, pp. L127-L131
With the Hubble Space Telescope's Wide Field Planetary Camera 2 we have obt
ained a deep, H alpha image of the relatively young ejection-type nebula M1
-67 around the runaway Population I Wolf-Rayet star WR 124 (WN 8). This ima
ge shows a wealth of complex detail, some of which have never been seen bef
ore in such a nebula. In particular, large arcs of nebulosity extend around
the central star yet with no overall global shell structure to the nebula
and no clear bipolar signature as claimed by Sirianni et al. In addition, n
umerous bright, mostly unresolved knots of emission, each less than or simi
lar to 10(-4) M-circle dot, occur in the inner part of the nebula, often su
rrounded by what appear to be their own local "wind" diffuse bubbles. Is th
is the first direct evidence of spatially resolved hot clumps being ejected
from a hot central star?
