| Abstract: | The Stripe82 has been repeatedly observed by SDSS (Sloan Digital Sky Survey) from 1998 to 2004, so as to provide us with opportunities to investigate the light variations of related objects. In this work, 29 broad-line LINERs (low-ionization nuclear emission line regions) in the Stripe82 are selected from the catalog LMCC (Light-Motion Curve Catalogue) to study their light variations. By comparing with the photometric measurements of the normal galaxies in LMCC, four candidates which possibly have light variations are picked up. Finally, after further veri?cations, it is found that there are two LINERs (SDSS J004828.80-001241.5 and SDSS J030203.53+005159.5) exhibiting relatively obvious light variations. |
