... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... Recent studies indicate that stars are most likely forming within the binary and multiple systems. ... During several years we are conducting the observations of such multiple stellar systems at the BTA telescope in order to find their companions and study the properties therein. ... This star is interesting in that it may be a dynamically unstable multiple star, meaning that over time, such systems will split into individual stars. ...

... It was found in this way that the radio variations (5 MHz) followed the optical ones, but that the time delay was a linear function of time with the mean value being about 2370 days and with the rate of increase days/year. ... We take days/year as the test value. ... To show that the method has real abilities to determinate a value of of the time delay rate of increase in the light curves we again use Monte-Carlo simulation as it is explained in (1) and (2), but the actual value is 110 days/year. ...

... It is found that the metallisity distribution of disk stars has a gap which subdivide the disk population into two groups. The distribution may be described by the sum of two normal curves which are centered at [Fe/H]=-0.22 and +0.08. The curves can be interpreted as distributions of random errors in metallisity of sample stars. This leads to the conclusion that all stars in each group have actually the same value of [Fe/H]. ...
