Hen 2-155 and Hen 2-161 photometry and spectroscopy
Listed in IVOA Registry (Virtual Observatory)
We present a study of Hen 2-155 and Hen 2-161, two planetary nebulae which bear striking morphological similarities to other planetary nebulae known to host close-binary central stars.
Description
Both central stars are revealed to be photometric variables while spectroscopic observations confirm that Hen 2-155 is host to a double-eclipsing, post-common-envelope system with an orbital period of 3h 33m making it one of the shortest period binary central stars known.
The observations of Hen 2-161 are found to be consistent with a post-common-envelope binary of period ~1-day.
