Scientific paper

In late 2010 the Jupiter-family comet 103P/Hartley 2 was intensively observed by the EPOXI spacecraft and from many Earth-based observatories. We joined this effort and obtained spectral time series of HCN and CH3OH at millimeter wavelengths. Since the spectra were integrated simultaneously and they are velocityresolved, we could identify and compare the sources of the two molecules. Our results provide insights into the compositional structure of the comet's nucleus and are readily comparable with the spatially-resolved molecular observations from EPOXI [1].
