Reconstruction of the surface topography from single images with the photometric method
Bondarenko, N. V.; Dulova, I. A.; Skuratovsky, S. I. +1 more
The possibility of reconstructing the surface topography from single images with the photometric method in the linear approximation is analyzed. The photometric method or surface topography Reconstruction employs a statistical approach to the problem formulation and is the most mathematically correct. This method allows determination of the most p…
Reduction of photographic observations of asteroids to the reference frame of a single catalog
Chernetenko, Yu. A.
In 2000, the last international program of photographic observations of selected asteroids aimed at the determination of the mutual orientation of the dynamic and stellar coordinate systems came to an end. The Institute of Applied Astronomy of the Russian Academy of Sciences collected more than 25 000 observations for 15 asteroids spanning from 19…
On the probability of cryogenic mud volcanism on Titan
Alekseev, V. A.
Juxtaposing images of the surface of Titan made by the Huygens probe and photos of the mud volcano region on Earth (the Taman peninsula, the Caucasus) reveals similar geomorphologic features. This has led us to suggest the existence of cryogenic mud-volcanic activity on Titan. The role of liquid methane in supporting this process on Titan can be t…
