Research Abstract

The aim of this project is to derive the supernova rates in nearby early type galaxies by monitoring galaxies with medium size (60cm--105cm) telescopes that belong to some public astoronomical observatories in Japan. Main observations started in January 1997 with the cooperation of seven observatiories, and will continue for some years with more participants.
Supernovae in early type galaxies play an important role in the chemical and dynamical evolution of the galaxies themselves and their hot interstellar gas.
Each telescope with the R-band filter and chilled CCD camera observes several fields. The fields are selected to include the dense cores of nearby clusters of galaxies. Each fields are observed within two weeks after the latest observation. The flatfielding and the detection of new (or brighter) objects are automated. To inform the monitoring status, a WWW page is organaized (http : //www. netwave. or. jp/-yfujita/snow. html, written in Japanese). This is found to be quite useful to compensate the lack of observation for some fields with other observatories. Though we have not detected any supernovae so far, this project will still continue with cooperation with more observatories.
