Proposal Information for 2006A-0013


PI: Edward Schmidt, University of Nebraska-Lincoln, eschmidt1@unl.edu
Address: Department of Physics and Astronomy, Lincoln, Nebraska 68588-0111

Title: A Search for Type II Cepheids

Abstract: While type II Cepheids have considerable potential to contribute to our knowledge of the Galactic halo and thick disk, their usefulness is compromised by the relatively small number of such stars known. Since it can be argued that many remain undiscovered, I have undertaken a program to identify them in various large area sky surveys. This proposal requests observing time with the GCAM spectrograph on the 2.1-m telescope at Kitt Peak to complement photometry of possible type II Cepheids identified from a small part of the Northern Sky Variability Survey. It is the first phase of a program to exploit that survey and others to discover new type II Cepheids. I anticipate eventually being able to increase the number by an order of magnitude.
