... The only criterion used for inclusion of a star in the monitoring program was that the star had to be an X--ray source. ... He also found a similar relation between rotation period and X--ray flux. ... Thus, one is more likely to find periods for either more massive or more active stars. ... Because of this, the data are not very sensitive to periods longer than 11 days. ... Taking these biases as a whole, some of the higher FAP periods listed as just below one day may be just above one day. ...

... As the SN activity in the first generation stellar population must be small at present, the net SN rate in the vicinity of the Sun is approximately proportional to the local density of stars of second generation (or to the star formation rate, which is the same), especially for SN II and SN Ib. If a -like star formation of the first generation stars took place, a hump on the observed - showing the relative fraction of the first generation stars should be observed. ...
