Protostellar Disks
(Preview)
Title: The Location of the Snow Line in Protostellar Disks Authors: Morris Podolak The snow line in a gas disk is defined as the distance from the star beyond which the water ice is stable against evaporation. Since oxygen is the most abundant element after hydrogen and helium, the presence of ice gra...

Origem Loop
(Preview)
Title: The Origem Loop Authors: X. Y. Gao, J. L. Han The Origem Loop in the Galactic anticentre was discovered in 1970s and suggested to be a large supernova remnant. It was argued later to be a chance superposition of unrelated radio sources. We attempt to understand the properties of the Origem Loop...
