We performed new observations of an ultra-fast rotator of the spectral class K - the LO Peg star - in SAO RAS in 2014 and in Zvenigorod Observatory of INASAN in 2015. The light curves were used to build the maps of temperature inhomogeneities on the LO Peg surface in order to determine the longitudes corresponding to the location of active regions. The obtained measurements suggest the ongoing evolution...
Experiments have been conducted in a disc machine under rolling/sliding contact with EN31 and a mild steel disc pair in boundary lubrication. The wear has been modelled on the basis of asperity fatigue due to repetitive tensile stresses. The modelling requires information regarding damage depth and the number of cycles needed for fatigue to occur. This information was obtained by a theoretical analysis...
