J/A+A/539/A115  Main-belt asteroids polarimetric survey. II. (Gil-Hutton+, 2012)

Polarimetric survey of main-belt asteroids. II. Results for 58 B- and C-type objects. Gil-Hutton R., Canada-Assandri M. <Astron. Astrophys. 539, A115 (2012)> =2012A&A...539A.115G
ADC_Keywords: Minor planets ; Polarization Keywords: minor planets, asteroids: general - techniques: polarimetric Abstract: We present results of a polarimetric survey of main-belt asteroids at Complejo Astronomico el Leoncito (CASLEO), San Juan, Argentina. The aims of this survey are to increase the database of asteroid polarimetry, to estimate diversity in polarimetric properties of asteroids that belong to different taxonomic classes, and to search for objects that exhibit anomalous polarimetric properties. The data were obtained with the Torino and CASPROF polarimeters at the 2.15m telescope. The Torino polarimeter is an instrument that allows simultaneous measurement of polarization in five different bands, and the CASPROF polarimeter is a two-hole aperture polarimeter with rapid modulation. Description: Results for the objects observed during the polarimetric survey of main-belt asteroids. The observations were carried out during different observing runs between May 2004 and November 2009 at the 2.15m telescope of the CASLEO, San Juan, Argentina, using the Torino and CASPROF polarimeters.
