... The Thickness of Stellar Disks in Early-type Galaxies E. M. Chudakova* and O. K. Sil'chenko ** Sternberg Astronomical Institute, Lomonosov Moscow State University, Moscow, Russia Received August 19, 2013; in final form, October 30, 2013 Abstract--We suggest and justify a new photometric method enabling the derivation of the relative thickness of a galactic disk from the two-dimensional surface-brightness distribution of the galaxy in the plane of the sky. ... The galaxies are non-interacting. ...
