| 内容記述 | We acquired high resolution near-infrared spectra of comet 103P/Hartley-2 with NIRSPEC at the W. M. Keck Observatory and CRIRES at the ESO VLT, emphasizing primary volatiles before, during, and after the comet's close approach to Earth (July-December 2010; R(sub h) =1.62 right arrow 1.26 AU). We will present the mixing ratios for trace volatiles (C2H6, HCN, CH3OH, etc.), their rotational temperatures, and their spatial distributions in the coma both along the polar jet (UT 19.5 October) and nearly orthogonal to the jet (UT 22.5 October). |
