The Rosette nebula in the decameter range
Abstract
Radio isophotes of the NGC 2237 nebula are presented at 12.6 MHz and 25 MHz. Within the investigated frequency range the H II region can be observed in absorption. The average density of nonthermal radio emission between the source and observer, electron temperature, emission measure, electron density, mass and other parameters of the nebula are determined.
