Natasza Siodmiak, Nick Cox, Ryszard Szczerba, Pedro Garcia-Lario

TL;DR
This paper discusses the use of the AKARI infrared sky survey to identify and study post-AGB stars, which are in a late stage of stellar evolution characterized by infrared emission due to circumstellar dust.
Contribution
It introduces new photometric criteria for identifying post-AGB star candidates using AKARI survey data, extending previous infrared-based discoveries.
Findings
AKARI survey enables detection of obscured post-AGB stars.
New photometric criteria proposed for candidate selection.
Enhanced understanding of late stellar evolution stages.
Abstract
Obscured by their circumstellar dusty envelopes post-AGB stars emit a large fraction of their energy in the infrared and thus, infrared sky surveys like IRAS were essential for discoveries of post-AGBs in the past. Now, with the AKARI infrared sky survey we can extend our knowledge about the late stages of stellar evolution. The long-term goal of our work is to define new photometric criteria to distinguish new post-AGB candidates from the AKARI data.
