VizieR Online Data Catalog: V and Rc light curves of medium-bright PPNe (Hrivnak+, 2020)
Abstract
Observations were carried out with three different telescopes. The Valparaiso University Observatory (VUO) 0.4m campus telescope was the main one used. Each of the objects has been observed from the VUO, beginning in 2008 or 2009 and continuing through 2018, with the last observations made in 2018 May. Typical exposure times at the VUO ranged from 8 to 30 minutes for the different objects. The FWHM of the VUO images were typically 2.5"-3.0".
Two telescopes operated by the Southeastern Association for Research in Astronomy (SARA) were also used: the 0.9m at Kitt Peak National Observatory (SARA-KP) and the 0.6m Lowell telescope at Cerro-Tololo Interamerican Observatory (SARA-CT). Each was equipped with a CCD detector and standard Johnson BV and Cousins RI filters. In this program, we are using the V and RC filters. Three objects were observed with the SARA telescopes. These observations were also begun in 2008 or 2009 and continued through 2018 April. However, for each of the SARA telescopes, we went through a succession of three different detectors and in one case two different filter sets. (2 data files).- Publication:
