Abstract / Description:The Speckle camera of the 3.5 m Telescopio
Nazionale Galileo (TNG) has been used to measure
apparent sizes and shapes of a number of main belt
asteroids. The average size measurements are in a
generally good agreement with the results of
indirect IRAS-based radiometric techniques. The
measured shapes are compared with predictions
based on previously derived spin axis directions
and lightcurve photometry of some of the
observed objects. Also in this case the agreement
is reasonable and the speckle observations allow
us to discriminate in some cases between the two
pole solutions usually found for each object. No
clear evidence of binaries was found. The results
show that the TNG speckle camera can be a
powerful tool to resolve relatively large main
belt asteroids and to calibrate the results of
the IRAS survey.
