Theoretical spectra and evolutionary models that span the giant planet-brown dwarf continuum have been computed based on the recent discovery of the brown dwarf Gliese 229 B. A flux enhancement in the 4- to 5-micrometer wavelength window is a universal feature from jovian planets to brown dwarfs. Model results confirm the existence of methane and water in the spectrum of Gliese 229 B and indicate that its mass is 30 to 55 jovian masses. Although these calculations focus on Gliese 229 B, they are also meant to guide future searches for extrasolar giant planets and brown dwarfs.
基于最近发现的褐矮星格利泽229B，已经计算出了跨越巨行星 - 褐矮星连续体的理论光谱和演化模型。在4至5微米波长窗口中的通量增强是从木星类行星到褐矮星的一个普遍特征。模型结果证实了格利泽229B光谱中甲烷和水的存在，并表明其质量为30至55个木星质量。尽管这些计算聚焦于格利泽229B，但它们也旨在为未来寻找太阳系外巨行星和褐矮星提供指导。
