Activity in quasi-Hilda objects: A photometric approach

Abstract

We present the results of a search for quasi-Hilda objects that could be candidates for exhibiting cometaryactivity. To achieve this, observations of objects from the quasi-Hilda region in the MPCAT-OBS ObservationArchive were examined. We then analyzed the observed brightness and compared it with the expected values,looking for discrepancies between the two ( ). These deviations from their expected brightness could bethe result of weak cometary-like activity that does not manifest as an observable coma and/or tail. The values were analyzed and evaluated for objects in the quasi-Hilda region. We believe that the objects(30512) 2001 8 , (18916) 2000 44 , and 2017 158 are interesting candidates for searching for activity in thequasi-Hilda region. Additionally, some unnumbered objects are also noted as potentially interesting, althoughthey have few observations.
