surface brightness การใช้

• This gives a surface brightness of 23.9 mag / sq . arcsec.
• Empirically, surface brightness exhibits a peak at about M _ V =-23.
• It has a low surface brightness and has a diameter of 4.5 arcminutes.
• But the overall radio surface brightness is on the low side.
• These included calculations of the surface brightnesses and radii of stars.
• Because it is so diffuse, it has a low surface brightness.
• This surface brightness is independent of the galaxy s actual distance from us.
• By comparison, the darkest skies have a surface brightness of 23 mag / sq!
• Additionally, irregularities in the surface brightness are seen across the face of the shell.
• Low surface brightness dwarf galaxies are important sources of information for studying dark matter.
• Even first-ranked cluster galaxies do not have constant surface brightness.
• In an expanding universe, the surface brightness diminishes with distance.
• The Milky Way has a relatively low surface brightness.
• They appear elliptical-like, with large low surface brightness envelopes.
• Although moderately bright ( M V =-9.9 ?0.6 ), it has low surface brightness.
• It is a larger planetary with low surface brightness.
• Among them was a recently discovered class of stealth star systems called low-surface brightness galaxies.
• Overall, the disc has a very low surface brightness.
• Its accompanying nebula has very low surface brightness, partially because of its diameter of 40 arcminutes.
• The term involving the convergence magnifies the image by increasing its size while conserving surface brightness.
