"It has been shown that there are bright, complex organic molecules present in the coldest and densest parts of planet-forming disks," Calahan said.
Jenny Calahan, a doctoral student in astronomy and first author of the paper, which appears in Nature Astronomy, said the discovery was part happy accident, part building on previous work. Haystack Observatory also gratefully acknowledges the continuing support of the NASA/GSFC High-End Network Computing Group for consultation on high-performance COTS hardware that have greatly helped in the development of Mark 6.New research from the University of Michigan Department of Astronomy suggests that chemistry in late-stage planet development is fueled by ultraviolet rays, rather than cosmic rays or X-rays, and this new understanding provides a chemical signature that helps researchers trace exoplanets back to their cosmic nurseries in the planet-forming disks. Prototype Mark 6 systems are routinely in use for VGOS development work using the Westford Observatory and NASA/GGAO Observatory. and front panel Mark 6 systems use the same bare chassis as Mark 5, and existing Mark 5 chassis are upgradeable to Mark 6 compatibility by replacing all electronic components. Existing Mark 5 SATA modules are upgradeable to Mark 6 compatibility with an upgrade kit consisting of a new module backplane with a new high-reliability power connector at the rear and a new front panel with connections for two SAS2 data cables. In order to preserve as much investment as possible in existing Mark 5 systems and disk modules, Haystack Observatory is collaborating with Conduant Corporation in the design of the Mark 6 chassis and modules all software has been developed by Haystack Observatory.
