Synthetic Light Curves for Born Again Events: Preliminary Results

TL;DR

This paper discusses the creation of synthetic light curves for born again stars to aid in identifying slow transient events in upcoming large sky surveys and historical data.

Contribution

It introduces a new approach to generate theoretical light curves for born again stars, facilitating their detection in extensive observational datasets.

Findings

Preliminary synthetic light curves have been computed for born again stars.

These models will help identify slow transients like late helium flashes.

The project supports upcoming survey data analysis and historical data digitization.

Abstract

The development of surveys which will be able to cover a large region of the sky several times per year will allow the massive detection of transient events taking place in timescales of years. In addition, the projected full digitalization of the Harvard plate collection will open a new window to identify slow transients taking place in timescales of centuries. In particular, these projects will allow the detection of stars undergoing slow eruptions as those expected during late helium flashes in the post-AGB evolution. In order to identify those transients which correspond with late helium flashes the development of synthetic light curves of those events is mandatory. In this connection we present preliminary results of a project aimed at computing grids of theoretical light curves of born again stars.
