Description
The importance of long-period binaries for the formation and evolution
of planetary nebulae is still rather poorly understood, which in part is
due to the lack of central star systems that are known to comprise such
long-period binaries. Here, we report on the latest results from the
on-going Mercator-HERMES survey for variability in the central stars of
planetary nebulae. We present a study of the central stars of NGC 1514,
revealed to be a highly eccentric binary system with a period of more
than nine years, making it the longest known period central star to
date. The morphology of the nebula shows the clear shaping influence of
the binary in spite of its long period, highlighting that even wide
companions can have a very significant impact on mass loss evolution.
This study demonstrates not only the importance of wide binaries in late
stellar evolution but also the importance of long-term monitoring
campaigns which are only now possible due to modern high-stability
instruments and queue mode observing.
