The Stellar Structure of Irregular Galaxies. Face-on Galaxies

Tikhonov, N. A.

Stellar photometry of nearby irregular galaxies of the Local Group is used to identify and study the young and old stellar populations of these galaxies. An analysis of the spatial distributions of stars of different ages in face-on galaxies shows that the young stellar populations in irregular galaxies are concentrated toward the center, and form…

A Spectroscopic and Photometric Study of NGC 2685, the Prototype Polar-Ring Galaxy

Moiseev, A. V.; Burenkov, A. N.; Hagen-Thorn, V. A. +3 more

We present and analyze spectroscopic and photometric observations for NGC 2685, the prototype polar-ring galaxy. The spectroscopic data were acquired using the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences with the UAGS spectrograph and a scanning Fabry-Perot interferometer, while the photometric analysi…
