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.
