First Evidence of the Relation Between Jets in Planetary Nebulae and Mass Transfer and Accretion in Close Binaries12 Dec 2012, 12:00 UTC
The formation of asymmetric structures such as rings and jets in
planetary nebulae (PNe) has been a matter of debate for a long time. The
most popular hypothesis is that these features are produced in
interacting binaries. Using data obtained with ACAM imager and spectrograph on the
William Herschel Telescope,
for the first time astronomers have been able to reliably relate jet ejections to mass transfer and accretion in a
close binary in a planetary nebula.
