Fe emission lines, with the equivalent width reaching about 4000 eV, were discovered with ASCA from a few Galactic compact objects, including AX J2315 - 0592, RX J1802.1 +1804 and AX J1842.8 - 0423.
We also notice a short lived
emission line of
Fe II at 2.0888 micron which was present between April 9, 2008 to May 9, 2008.
