Description

In the alerts received by the Fink broker, we identified a number of diaObjects associated with stable Gaia stars that nevertheless triggered multiple detections in the Rubin alert pipeline within the Deep Drilling Fields.

After cross-matching these objects with the Gaia catalog of stable stars with magnitude G < 20.5 mag, we investigate a sample of eight such stars using Fink cutouts and prompt-processing difference images. The goal is to understand the artifacts responsible for these spurious alert triggers.
