Description

Continuum radio emission and hydrogen recombination line emission were measured at 2.37 GHz with the 64-m antenna at Goldstone. The radio emission has the same general distribution as the optical nebula. The electron temperature is estimated to be approximately 7.000 K. The excitation of the nebula is compared with current estimates of the ionizing flux from the exciting star, sigma Orionis. (orig./BJ)

Abstract (German)

Die Kontinuumemission und die Wasserstoffrekombinationslinienemission wurden bei 2,37 GHz mit der 64-m-Antenne in Goldstone, Calif., gemessen. Die Radioemission hat die gleiche allgemeine Verteilung wie der optische Nebel. Die Elektronentemperatur wird auf ungefaehr 7.000 K geschaetzt. Die Anregung des Nebels wird mit neueren Schaetzungen des ionisierenden Flusses vom anregenden Stern, sigma Orionis, verglichen. (orig./AK)
