The second release of the Toru\'n catalogue of Galactic post-AGB objects: new classification scheme

TL;DR

This paper presents the second release of the Toruń catalogue, a comprehensive database of Galactic post-AGB objects, introducing a new classification scheme and including new data to facilitate the study of stellar evolution.

Contribution

It provides an updated, accessible catalogue with a new classification scheme and expanded data, aiding research on late stellar evolution stages.

Findings

Introduction of a new classification scheme for post-AGB objects

Inclusion of a significant number of new objects and data

Discussion on the termination of the AGB phase

Abstract

The investigation of post-AGB objects (proto-planetary nebulae) is very important from the standpoint of physical and chemical changes occurring during the late stages of stellar evolution. The Toru\'n catalogue of Galactic post-AGB and related objects is an evolutive catalogue containing astrometric, photometric and spectroscopic data as well as HST images for all known post-AGB objects and candidates in our Galaxy. This free-access catalogue can serve as an ideal tool to study different groups of post-AGB objects, especially due to the fact that all information is gathered in one place. The second release of our catalogue introduces a simple classification scheme of post-AGB objects and includes a significant number of new objects, photometric data, spectra and images. Here, using objects from the catalogue we consider the problem of the termination of the AGB phase.
