Overview

Observational analysis characterizes central stars in planetary nebulae, suggesting NIR may reduce extinction challenges.

Key Points

  • NIR photometry can accurately characterize central stars of planetary nebulae despite high extinction levels.
  • The study identifies 1274 CSPNe, with 14 showing large infrared excess and 56 as potential eclipsing binaries.
  • Using data from the VVVX survey, we investigated the NIR properties and evolutionary status of CSPNe.
  • This work highlights the potential for NIR observations to enhance the understanding of CSPNe's nature and companions.
