J/A+A/513/A75       Polarimetry of stars in NGC 5617         (Orsatti+, 2010)

Polarimetry of an intermediate-age open cluster: NGC 5617. Orsatti A.M., Feinstein C., Vergne M.M., Martinez R.E., Vega E.I. <Astron. Astrophys., 513, A75-75 (2010)> =2010A&A...513A..75O
ADC_Keywords: Clusters, open ; Polarization Keywords: dust, extinction - open clusters and associations: individual: NGC 5617 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). File Summary:
