... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...

... According to the current estimates, a few percent of Main Sequence B5-F5 stars reveal strong surface magnetic fields reaching the values of tens of kilogauss, which is an order of magnitude greater than the maximal magnetic field in sunspots. ... An important direction in the study of magnetic stars is the study of binary and multiple systems with magnetic components using the techniques of spectroscopy and high angular resolution interferometry. ...
