Solar P-angle Alignment in GONG Dopplergrams
Anna L. H. Hughes, Irene Gonzalez-Hernandez, Sean G. McManus +2
In helioseismic studies, an observational parameter of primary concern is the P-angle, the angle along which lies the solar axis of rotation for a given image. For the six observin…
HMI Synoptic Maps Produced by NSO/NISP
Anna L. H. Hughes, Luca Bertello, Andrew R. Marble +3
Recently, the National Solar Observatory (NSO) Solar-atmosphere Pipeline Working Group has undertaken the production of synoptic maps from Helioseismic and Magnetic Imager (HMI) ma…
GONG ClassicMerge: Pipeline and Product
Anna L. H. Hughes, Kiran Jain, Shukur Kholikov +1
A recent processing effort has been undertaken in order to extend the range-of-coverage of the GONG merged dopplergrams. The GONG-Classic-era observations have now been merged to p…
Zeemanfit: Use and Development of the solis_vms_zeemanfit code
Anna L. H. Hughes, Jack Harvey, Andrew R. Marble +1
The purpose of the SOLIS Zeemanfit Code is to provide a straight-forward, easily checked measure of the total magnetic-field strength in the high-strength umbral regions of the sol…
Global variation of the dust-to-gas ratio in evolving protoplanetary discs
Anna L. H. Hughes, Philip J. Armitage
Recent theories suggest planetesimal formation via streaming and/or gravitational instabilities may be triggered by localized enhancements in the dust-to-gas ratio, and one hypothe…
Particle transport in evolving protoplanetary disks: Implications for results from Stardust
Anna L. H. Hughes, Philip J. Armitage
Samples returned from comet 81P/Wild 2 by Stardust confirm that substantial quantities of crystalline silicates were incorporated into the comet at formation. We investigate the co…
