Photometric observations of Cepheids from the ASAS-3 catalog: Photoelectric BV I c observations of 46 low-amplitude Cepheids
Tóm tắt
From December 2006 to January 2008, we performed 1699 BV I
c observations for 46 low-amplitude Cepheids discovered in the course of the ASAS project using the 76-cm telescope of the South-African Astronomical Observatory (SAAO). We provide the tables of observations and V light and B-V and V-I
c color curves. These new observations, along with data from the ASAS-3 catalog, have been used to improve the elements of the light variations. Our data allow the number of known Galactic low-amplitude Cepheids to be almost doubled. This makes it possible to increase the number of distance indicators suitable for studying the structure of the inner Galactic arms by almost 15%.
