... o ); background emission is visible to the right of fhe well-known Rosette Nebula ... the background near the Rosette Nebula is emission from the nearest exterior spiral ...
... The optical spectrum of the nebula contains emission components of the resonance sodium doublet NaI D1 2, emission in H alpha, and emission bands of the C2 molecule. ...
... One such example is RAFGL2688 (the Egg Nebula) for which Crampton et al. (1975) observed emission features of the molecule in a medium resolution spectrum. ...
... Emission line spectrum belongs to rerified nebula with the temperature of T=1100K. Emission spectrum superimposed on the red ... Note that emission lines of the nebula fall in a more rapid rate than the stellar continuum. ...
... Distribution of recombination line H110 alpha emission on a wave length 6.2cm in the Orion Nebula was obtained with the radiotelescope RATAN-600 with the resolution 40" x 6' x 9.7 km/s ( figure 1 ). ...
... Absorption and distribution of emission intensity of 21 cm radio line were observed in the region of Orion Nebula with angular resolution of 2 ' x 20 ' and in the Cygnus A. Parameters of the antenna sector in the whole region of hights were obtained with ...
... IFP observations reveal a giant bipolar nebula around unique WO (oxygen WR) star in the dwarf galaxy IC 1613. ... This figure shows monochromatic Ha image obtained with IFP by integrating the emission over all spectral channels of the line. ...
... Direct measurements of the H alpha emission from the nebula filaments ( Lozinskaya 1976 ) confirmed the presence of expansion velocities up to 100 km/s. The interstellar-gas distribution around this SNR was investigated in the HI radio line by Assousa et ...
... The results of photometry allow statement that the offered candidates into optical pulsar are emission knots of the nebula and background stars. ...
