Araucaria: NGC 3109 Cepheids VI phot.
Listed in IVOA Registry (Virtual Observatory)
We have obtained mosaic images of NGC 3109 in the V and I bands on 74 nights, spanning approximately 1yr.
Description
From these data, we have conducted an extensive search for Cepheid variables over the entire field of the galaxy, resulting in the discovery of 113 variables with periods ranging from 3.4 to 31.4days. In this sample, 76 Cepheids, including many long-period variables, were not known before.
For the previously known 45 Cepheids in this galaxy, our data proved that reported periods were wrong for 14 objects; for nearly all other previously known Cepheid variables, we were able to significantly improve on the periods.
