Binary central stars of planetary nebulae in the Large Magellanic Cloud

Puntos clave

Nine binary central stars were identified within the planetary nebulae in the Large Magellanic Cloud.
Binary CSPNe exhibited orbital periods ranging from 0.24 to 23.6 days, indicating diverse characteristics.
The fraction of binary CSPNe found suggests a substantial number within the Large Magellanic Cloud's population.
Data was gathered from the OGLE dataset, providing insights into the binary nature of these celestial objects.

Resumen

Abstract We used the OGLE data to search for binary central stars of planetary nebulae (CSPNe) in the Large Magellanic Cloud (LMC). Nine binary CSPNe with periods between 0.24 and 23.6 days were discovered. The obtained fraction of binary CSPNe for the LMC PNe is without correcting for incompleteness.
