On the Distance to Nearby Dwarf Galaxy NGC 1569
Karachentsev, I. D.; Makarova, L. N.
We present stellar photometry of two HST/WFPC2 fields situated at the far periphery of the poststarburst galaxy NGC 1569. Their F606W and F814W images have been taken from the HST data archive. Judging by the obtained color-magnitude diagrams, we suggest presence of the old disk population (old red giants) of NGC 1569, which extends as far as Fiel…
Kinematic Analysis of Near and Far Stars in the Hipparcos Catalog
Vityazev, V. V.; Drobit'ko, E. V.
The proper motions of stars in the main sequence and of luminosity class III giants are analyzed kinematically. A new method has been used for reliably separating all the parameters of the Ogorodnikov-Milne model based on representing the proper motions of the stars in coordinate systems whose poles lie on each of the three principal axes of the g…
