Scientific achievements, Solar system
1998:
The RATAN-600 observations of solar active regions:
-
experimental evidence was found of the existence of cyclotron emission
lines, earlier predicted by Zheleznyakov V.V. and Zlotnik E.Y.; the line
detected was located in a bright source of thermal nature and had an
emission band of 10-12% at the wavelength of 8.5cm, the brightness
temperature of 107 K;
(Collaboration with the IAP RAS).
-
direct measurements of the magnetic field in the coronal hole at the
bottom of the corona were performed, the magnetic field strength
(the calculations were carried out as part of the thermal bremsstrahlung
mechanism of radio emission generation of the solar plasma in the weak
magnetic field) increases from the values of 0.2G at the photosphere
level up to 7-10G at the level of radio emission formation at the
wavelength of 18cm and is then remains unchanged (or decreases slightly)
down to the level of radio emission formation at the wavelength of 30cm.
(Collaboration with MAO RAS).
