Spectroscopic observationsHS 0209+0832 was observed using HST/STIS in the FUV on 10 January 19994. Two exposures of 2,110 s and 1,140 s were taken using the MAMA detector and the E140M grating, covering the wavelength range 1,150−1,710 Å with a resolving power of R ≈ 45,800. We used the Hubble Advanced Spectral Products (HASP) spectrum, which combined the … Read more
