... 2011: . ... The measurements of the apparent diameter of a long-period variable star R Leo, a cold pulsating giant in the last stage of evolution, the scales of which are hundreds of times larger than the Sun were conducted at the 6-m BTA telescope. ... The discovered effect explains the observed anomalously large values of the pulsar slowdown indices, as well as the known differences in the estimates of their ages with the ages of the corresponding supernova remnants. ...

Rotationally resolved visible spectroscopy ( 6000 to 9500 A) of (7) Iris is presented. Within a few percents, no variation in Iris' visible spectrum over a rotational period has been found. ... The resulting velocity values are fairly high, but not incompatible with the values suggested by the present knowledge of catastrophic break-up phenomena and by the observational constraints put by asteroid families. ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...
