WebThe chromospheric Ca II H & K line emission ratio of WASP-19 quantified by log (R ) = -4.5 ± 0.03 (Anderson et al. 2013, Knutson et al. 2010) quantifies the high level of chromospheric activity ... Narrow-band filters are astronomical filters which transmit only a narrow band of spectral lines from the spectrum (usually 22 nm bandwidth, or less). They are mainly used for nebulae observation. Emission nebulae mainly radiate the doubly ionized oxygen in the visible spectrum, which emits near 500 nm wavelength. These nebulae also radiate weakly at 486 nm, the Hydrogen-beta line.
