Abstract:
We present polarimetric observations in the UBVRI bands of 72 stars
located in the direction of the medium age open cluster NGC 5617. Our
intention is to use polarimetry as a tool in membership
identification, by building on previous investigations intended mainly
to determine the cluster's general characteristics rather than provide
membership suitable for studies such as stellar content and
metallicity, as well as study the characteristics of the dust lying
between the Sun and the cluster.
Description:
The observations were carried out using the five-channel
photopolarimeter of the Torino Astronomical Observatory attached to
the 2.15m telescope at the Complejo Astronomico El Leoncito (CASLEO;
Argentina). They were performed over eight nights (June 27-30, 2006
and June 15-18, 2007).
