- Description
- UV to mm optical constants of four Mg- and Fe-rich amorphous silicates Mg$_{(1-x)}$Fe$_x$SiO$_3$, x=0.1 - 0.2 - 0.3 - 0.4, at 10, 100, 200 and 300 K. The optical constants are calculated from mass absorption coefficients measured in the 5 - 1000 µm (2000-10 cm-1) range and extrapolated in the range 0.024 - 5 µm and 1000 - 100000 µm.
