Results of laboratory measurements of meteorites and terrestrial silicates
Laboratory measurements were carried out at the photometer-polarimeter of Institute of Astronomy
of V.N. Karazin Kharkiv National University. Phase curves of brightness and polarization
were obtained for each sample in the phase angle range from 1 deg to 20-30 deg (Lupishko D.F. and Belskaya I.N. Icarus, v. 78, p. 395, 1989).
All samples were crushed and had a similar texture with particle sizes ≤50 microns.
Albedos of samples were measured at the phase angle of 5 deg.
