| Summary: | Temperature acts as the main indicator of the energy emitted by
celestial bodies, including stars. Accurate knowledge of a star's
effective temperature forms a solid basis for interpretation of
observational data and further analysis. The Planetary Nebula (PN) is a
short transition stage for low to medium mass stars. In the case of PNs,
the temperature of the ionizing star can be said to be crucial
information to become the initial basis for understanding the ionization
structure of complex PNs.
This research focuses on analyzing the effective temperature of
the central star of the planetary nebula DdDm-1, PN with a binary
central star located in the galactic halo. Data for this study were
obtained from IUE and HST FOS spectroscopic observations.
The continuum fitting method using the Planck function is used
to approach the effective temperature value of the PN central star.
Comparisons were also made with other methods such as stoy
temperature, Zanstra temperature, etc., to evaluate the advantages and
limitations of the continuum fitting method in determining effective
temperature.
