• There are several prominent ultraviolet Balmer lines with wavelengths shorter than 400 nm.
• Balmer lines can appear as planetary nebulae, the Balmer lines are emission lines.
• Balmer lines can appear as planetary nebulae, the Balmer lines are emission lines.
• On this sample, the Balmer lines for heavy hydrogen were seven times as intense.
• Alpha, Beta, Gamma Balmer lines are visible, other lines are indistinguishable from the noise.
• The hydrogen Balmer lines, the extreme metal deficiency results in weak metal lines and yields a spuriously early spectral type.
• In true-colour pictures, these nebula have a distinctly pink colour from the combination of visible Balmer lines that hydrogen emits.
• Because the Balmer lines are commonly seen in the spectra of various objects, they are often used to determine radial velocities due to doppler shifting of the Balmer lines.
• Because the Balmer lines are commonly seen in the spectra of various objects, they are often used to determine radial velocities due to doppler shifting of the Balmer lines.
• In 1910 Hans Rosenberg published a diagram plotting the apparent magnitude of stars in the Pleiades cluster against the strengths of the Calcium K line and two Hydrogen Balmer lines.
• O-type stars have dominant lines of absorption and sometimes emission for C III ) and neutral helium lines, strengthening from O5 to O9, and prominent hydrogen Balmer lines, although not as strong as in later types.
• The spectrum of A-class stars such as IK Pegasi A show strong Balmer lines of hydrogen along with absorption lines of ionized metals, including the K line of ionized calcium ( Ca II ) at a wavelength of 393.3 nm.
• Massive yet non-supergiant entities known as " Be stars " are main-sequence stars that notably have, or had at some time, one or more Balmer lines in emission, with the hydrogen-related electromagnetic radiation " B ( e ) " or " B [ e ] " stars possess distinctive neutral or low ionisation emission lines that are considered to have'forbidden mechanisms', undergoing processes not normally allowed under current understandings of quantum mechanics.
